SEYMOUR, Circuit Judge. “[OJnce you begin the process of segregation, it has its own inertia. It continues on without enforcement.” This comment by one expert on segregation in schools succinctly summarizes the state of affairs in Topeka. As a former de jure segregated school system, Topeka has long labored under the duty to eliminate the consequences of its prior state-imposed separation of races. Brown v. Board of Educ., 349 U.S. 294, 75 S.Ct. 753, 99 L.Ed. 1083 (1955). The district court concluded that Topeka has fulfilled that duty, and that the school system is now unitary. Because we are convinced that Topeka has not sufficiently countered the effects of both the momentum of its pre-Brown segregation and its subsequent segregative acts in the 1960s, we reverse. Specifically, we hold that the district court erred in placing the burden on plaintiffs to prove intentional discriminatory conduct rather than according plaintiffs the presumption that current disparities are causally related to past intentional conduct. We are convinced that defendants failed to meet their burden of proving that the effects of this past intentional discrimination have been dissipated. We also reverse the district court’s holding that the Topeka school district has not violated Title VI. However, we affirm the court’s dismissal of the Governor of the State of Kansas and its ruling that the State Board of Education bears no liability for segregation in Topeka’s schools. I. LEGAL HISTORY Prior to 1954, a Kansas statute permitted certain cities to maintain separate schools for white and black children below the high school level. In 1941, however, the Kansas Supreme Court held segregation in Topeka’s junior high schools to be unconstitutional. See Graham v. Board of Educ., 153 Kan. 840, 114 P.2d 313 (1941) (separate facilities not equal). Topeka was thus legally permitted to operate segregated schools only at the elementary level. The Topeka Board of Education operated such a system. In 1951, black citizens of Topeka filed a class action challenging the constitutionality of the Kansas law authorizing school segregation. Brown v. Board of Educ., 347 U.S. 483, 74 S.Ct. 686, 98 L.Ed. 873 (1954) (Brown I), followed, beginning a new era of American jurisprudence by bringing an end to the doctrine of “separate but equal” and declaring segregation unconstitutional. The Topeka Board of Education did not wait for the decision in Brown I before taking steps towards desegregating Topeka’s elementary schools. It began that process in 1953 by permitting black students to attend two formerly all-white schools. It then gradually increased the number of schools black students might attend. Accordingly, when the Supreme Court considered the question of the relief appropriate in school desegregation eases, it noted that “substantial progress” had already been made in Topeka. Brown v. Board of Educ., 349 U.S. 294, 299, 75 S.Ct. 753, 756, 99 L.Ed. 1083 (1955) (Brown II). On remand, the district court criticized one aspect of the Board’s desegregation plan but described it overall as “a good faith effort to bring about full desegregation in the Topeka Schools in full compliance with the mandate of the Supreme Court.” Brown v. Board of Educ., 139 F.Supp. 468, 470 (D.Kan.1955). The court retained jurisdiction of the case, and the decision was not appealed. Nineteen years later, in 1974, the Office of Civil Rights (OCR) of the Department of Health, Education, and Welfare (HEW) notified the Topeka school district that it was not in compliance with section 601 of Title VI of the Civil Rights Act of 1964. After the Topeka Board of Education failed to adopt a plan designed to remedy the noncomplying conditions identified by OCR, HEW began administrative enforcement proceedings against the Topeka school district. The Board filed suit in federal court and obtained a preliminary injunction against the administrative proceeding on the ground that the district court’s 1955 decision was a final order, and that the school district was still operating under that court order and still subject to the court’s jurisdiction. HEW was thereby precluded from taking administrative action. See generally Brown v. Board of Educ., 84 F.R.D. 383, 390-91 (D.Kan.1979). In 1976, the Board submitted a plan acceptable to HEW, and both the administrative proceeding and the suit in federal court were dismissed. The Board implemented the plan over the next five years. In 1979, a group of black parents and children sought to intervene in Brown as additional named plaintiffs on the ground that they were members of the original class and that the original named plaintiffs no longer had a sufficient interest in the matter to represent their interests. The intervenors asserted that Topeka has failed to desegregate its schools in compliance with the Supreme Court’s mandate, and that the Topeka school district currently maintains and operates a racially segregated school system. Their request to intervene was granted. See Brown, 84 F.R.D. 383. A long discovery and motion stage followed the granting of the intervenors’ motion. Trial took place in October 1986. The court found the Topeka school district to be an integrated, unitary school system. Brown v. Board of Educ., 671 F.Supp. 1290 (D.Kan.1987). The court also held that the Topeka school district had not violated Title VI of the Civil Rights Act of 1964, dismissed the Governor of Kansas from the case, and found that the State Board of Education bore no liability for racial conditions in the school district. This appeal followed. II. BRIEF FACTUAL HISTORY A. Population Change In 1950, Topeka’s population was approximately 10% black. While Topeka’s population grew significantly until 1970 and then dropped, the black percentage of the population remained approximately the same. The Hispanic population of Topeka has been slightly less than 5% since 1970. Other minorities make up less than 1.5% of the population. The distribution of Topeka’s population has changed more significantly than its composition. In general, the outer parts of Topeka, particularly on the western side, have grown considerably in population, while the inner city has declined. Until recently, the western side of Topeka was almost exclusively white. The black population of Topeka was concentrated in a few areas in the center of the city in the 1950s; it has since spread widely throughout the eastern part of the city and has gradually begun to move into the western side of Topeka. The percentage of black and minority children in the Topeka schools has long been higher than the percentage of blacks and minorities in the Topeka population as a whole and has risen over time. In 1952, black students constituted 8.4% of the total number of students in Topeka. By 1966, the percentage of black students in the Topeka school district was 11.6% and the percentage of minority students was 16.0%. In 1975, black students constituted 14.7%, and minority students 20.9%, of the school population. The latest figures used at trial, those for the 1985 school year, showed 18.4% black and 25.95% minority children in the system. B. Elementary Schools In 1951, four Topeka elementary schools were reserved for black children, Buchanan, McKinley, Monroe, and Washington. Eighteen elementary schools educated white children. Black children were bused to their schools; white children attended neighborhood schools. 671 F.Supp. at 1291. Under the four-step plan approved by the district court in 1955, all elementary schools were to be opened by September of 1956 to black and white children under a neighborhood school policy. Id. at 1293. As a result of the new neighborhood school policy, three schools remained all- or virtually all-black (Buchanan (100%), Monroe (100%), Washington (99.4%)), and two others became more than 20% black in a school district with a black elementary student population of less than 10%. McKinley was closed. During the late 1950s, the school district acquired by annexation the Avondale (outer Topeka, south) and Highland Park (middle and outer Topeka, east) school districts as well as other territory on the edges of the district. Existing schools within the acquired area were either primarily white or primarily black. As school enrollments grew and the population began to shift, the school district began to close elementary schools in the inner part of the city and open them in the rapidly growing outer part of the city. Two of the closed schools were former de jure black schools (Buchanan, and Washington); another de jure school (McKinley) had already been closed. The new schools were built in the newly acquired white areas and opened with all or virtually all white students. Racial statistics were not kept in an organized fashion from 1956 to 1966. In 1966, the school district operated thirty-five elementary schools. There were some white students in every school. Minority students were present in thirty-two schools. Nineteen of the schools were 90 + % white. An additional seven schools were 80-90% white. Four schools were more than 50% minority, and a fifth was almost 50%. The highest percentage of minority students was 93.1% (Parkdale), and the lowest was 0% (Lyman, McEa-chron, and Potwin). Sixty-five percent of white students attended 90 + % white schools and an additional 18.7% attended 80-90% white schools. Close to half of all minority students attended 50 + % minority schools. A second major reorganization of the elementary schools took place in the late 1970s, after the HEW complaint was filed. Eight elementary schools closed over a six-year period, including the last of the four former de jure black schools (Monroe). In September 1982, when the reorganization had ended, minority and white students were present in each of the district’s twenty-six elementary schools. Five schools were 90 + % white, and another seven were 80-90% white. Four schools were 50 + % minority, two of them were schools that had been 50 + % minority since 1966. The highest percentage of minority students was 60.6% (Highland Park North), and the lowest was 3.4% (McClure). Close to one-quarter of all white students attended the 90 + % white schools, and another third attended 80-90% white schools, total-ling 58% overall. The percentage of minority students in 50 + % minority schools was 35.5%. This was the status of the elementary schools three years after plaintiffs moved to intervene in this lawsuit on the grounds that the school system had not met its mandate to desegregate. With one or two exceptions, the relative percentages of white and minority students in the elementary schools have changed only by two or three percentage points since that time. The most significant change is that the schools with the highest white percentages have gained some minority students. Thus, in 1985, the lowest percentage of minority students in any school was 7.2% (McClure). C. Secondary Schools In 1954, the Topeka school district operated six junior highs and one high school. Two schools were 90 + % white, and three were 80 + % white. The estimated percentage of black students at the junior high schools ranged from 1.7% (Roosevelt) to 30% (East Topeka). While the dissent emphasizes that segregation was not mandated by law for the secondary schools when Brown I was decided, and the student bodies were racially mixed, Linda Brown Smith testified that the junior high school she attended in 1955 (Curtis) had an all-white faculty. When she entered Topeka High school, she recalls that it had one black faculty member. During the late 1950s-early 1960s period of annexations and building, two junior high schools joined the school system, and three junior highs were built. At the high school level, Highland Park high school was annexed, and Topeka West high school was built. All of these schools were in the newly acquired white outer part of the school district and opened as white or primarily white schools. 671 F.Supp. at 1299. In 1966, there were thus eleven junior high and three high schools. At that time, the average minority percentage for the junior high and high schools was 15.3% and 14.9%, respectively. Of the junior highs, five had 90 + % white students and another three had 80-90% white students; one had 50 + % minority students. The highest percentage of minority students at one school was 61.8% (East Topeka), and the lowest percentage was 0% (Capper). Of the high schools, Topeka High was nearly one-quarter minority, Highland Park High had close to 15% minority students, and Topeka West had .4% minority students. French junior high school opened in 1970 in the southwestern part of the school district as a primarily white school. 671 F.Supp. at 1299. The reorganization of the late 1970s in response to the HEW complaint included the junior high schools. Two junior highs closed in 1975. In 1980, five more junior highs closed and two schools were opened as the district shifted from a junior high (6-3-3) to a middle school (6-2-4) format. In 1981, after the end of the reorganization, there were six middle schools in the Topeka school district. Two were 90 + % white and one was 80-90% white. The highest percentage of minority students was 45.7% (Eisenhower) and the lowest 5.5% (French). By 1985, the relative percentages at some schools had altered by approximately 5%, but the pattern across the district had not changed. The percentage of minority students at the three high schools was 39.8% (Highland Park), 32.5% (Topeka High), and 5.25% (Topeka West) in 1981, and 33.6% (Highland Park), 30.9% (Topeka High), and 7.9% (Topeka West) in 1985. III. THE PARTIES All of the parties to this case have changed. The original plaintiff children have long since left the Topeka school system. The school district has been reorganized, and the State Board of Education came into existence in 1969. These changes have affected the posture of the litigation to some extent. The original named plaintiffs represented black elementary school children and their parents. Current named plaintiffs represent black children throughout the school system and their parents. The school district grew considerably in size as the city of Topeka annexed territory, although the school district’s boundaries were fixed about 1960 while the city continued to grow. The district was also renamed Unified School District # 501 as part of a state-wide reorganization of school districts in 1965. 671 F.Supp. at 1292. The State Board of Education is the product of a 1966 state constitutional amendment. Its powers differ considerably from those of its predecessor. Id.) Brief for Individually-Named Defendants Associated with the State Board of Education at 1, 3-4. IV. GENERAL PRINCIPLES OF UNITARINESS Unitariness is a finding of fact reviewed under the clearly erroneous standard. Before we assess the status of school desegregation in Topeka, we set forth the principles that guide our consideration of the unitariness issue. The district court defined a unitary school system as “one in which the characteristics of the 1954 dual system either do not exist or, if they exist, are not the result of past or present intentional segregative conduct of” the school district. 671 F.Supp. at 1293. These are necessary ingredients in a unitariness determination because once a violation is found, “[t]he Board has ... an affirmative responsibility to see that pupil [and faculty] assignment policies and school construction and abandonment practices ‘are not used and do not serve to perpetuate or re-establish the dual school system.’ ” Dayton Bd. of Educ. v. Brinkman, 443 U.S. 526, 538, 99 S.Ct. 2971, 2979, 61 L.Ed.2d 720 (1979) (Dayton II) (quoting Columbus Bd. of Educ. v. Penick, 443 U.S. 449, 460, 99 S.Ct. 2941, 2948, 61 L.Ed.2d 666 (1979). An additional essential requirement of unitariness, however, is whether “school authorities [have made] every effort to achieve the greatest possible degree of actual desegregation, taking into account the practicalities of the situation.” Davis v. Bd. of School Comm’rs, 402 U.S. 33, 37, 91 S.Ct. 1289, 1292, 28 L.Ed.2d 577 (1971); see also Swann v. Charlotte-Mecklenburg Bd. of Educ., 402 U.S. 1, 26, 91 S.Ct. 1267, 1281, 28 L.Ed.2d 554 (1971). To determine whether a school district has become unitary, therefore, a court must consider what the school district has done or not done to fulfill its affirmative duty to desegregate, the current effects of those actions or inactions, and the extent to which further desegregation is feasible. After a plaintiff establishes intentional segregation at some point in the past and a current condition of segregation, a defendant then bears the burden of proving that its past acts have eliminated all traces of past intentional segregation to the maximum feasible extent. A. Current Condition of Segregation The actual condition of the school district at the time of trial is perhaps the most crucial consideration in a unitariness determination. The plaintiff bears the burden of showing the existence of a current condition of segregation. The case law is decidedly unclear as to the precise meaning of that term. In our view, a plaintiff must prove the existence of racially identifiable schools, broadly defined, to satisfy the burden of showing a current condition of segregation. Racially identifiable schools may be identifiable by student assignment alone, in the case of highly one-race schools, or by a combination of factors where the school is not highly one-race in student assignment. “What is or is not a segregated school will necessarily depend on the facts of each particular case. In addition to the racial and ethnic composition of a school’s student body, other factors, such as the racial and ethnic composition of faculty and staff and the community and administration attitudes toward the school, must be taken into consideration.” Keyes v. School Dist. No. 1, 413 U.S. 189, 196, 93 S.Ct. 2686, 2691, 37 L.Ed.2d 548 (1973). Although virtual one-race schools “require close scrutiny,” they are not always unconstitutional. Swann, 402 U.S. at 26, 91 S.Ct. at 1281. Their existence in a system with a history of de jure segregation, however, establishes a presumption that they exist as the result of discrimination and shifts the burden of proof to the school system. Id. The presence of essentially one-race schools is thus sufficient to satisfy a plaintiffs initial burden of showing a current condition of segregation. Courts have used various standards to define “one-race schools.” Standards may appropriately differ from school district to school district because the percentage of minority students may likewise vary. Whatever the minority percentage district-wide, however, it is clear that a school with 90 + % students of one race is a predominantly one-race school. Moreover, this is true whether the students at the school in question are white or minority. Where racial imbalance in student assignment is still extreme in a system that formerly mandated segregation, appellate courts have reversed findings of unitariness without looking to other factors. However, no particular degree of racial balance is required by the Constitution. A degree of imbalance is likely to be found in any heterogeneous school system. Therefore, the existence of some racial imbalance in schools will often not be conclusive in itself. Where numbers alone are insufficient to define racially identifiable schools, courts look to demography, geography, and the individual history of particular schools and areas of the city. While a multi-race school cannot be classified as racially identifiable merely by tallying up the race of the students who attend it, such a school may be racially identifiable “simply by reference to the racial composition of teachers and staff, the quality of school buildings and equipment, or the organization of sports activities,” among other factors. Swann, 402 U.S. at 18, 91 S.Ct. at 1277. These factors alone can establish a prima facia case of a constitutional violation. Id. Therefore, a plaintiff may prove a school to be racially identifiable by factors that may, but need not, include student assignment. B. The Parties’ Burdens Once a plaintiff has proven the existence of a current condition of segregation, the school district bears the substantial burden of showing that that condition is not the result of its prior de jure segregation. Under the relevant Supreme Court decisions, mere absence of invidious intent on the part of the school district is not sufficient to satisfy its “heavy burden” of proof; the district’s duty is to act' affirmatively, not merely to act neutrally. “[T]he measure of the post-Brown I conduct of a school board under an unsatisfied duty to liquidate a dual system is the effectiveness, not the purpose, of the actions in decreasing or increasing the segregation caused by the dual system. As was clearly established in Keyes and Swann, the Board had to do more than abandon its prior discriminatory purpose. The Board has had an affirmative responsibility to see that pupil assignment policies and school construction and abandonment practices ‘are not used and do not serve to perpetuate or re-establish the dual school system.’ ” Dayton II, 443 U.S. at 538, 99 S.Ct. at 2979 (emphasis added) (citations omitted). See also Swann, 402 U.S. at 26, 91 S.Ct. at 1281 (burden on school board to establish current racial composition of schools not the result of their present or past actions). The school district must show that no causal connection exists between past and present segregation, not merely that it did not intend to cause current segregation. The causal link between prior and current segregation is not snapped by the absence of discriminatory intent alone, or even by a firm commitment to desegregation, where it is not accompanied by action that in fact produces a unified school district. Id. The dissent clearly has misconstrued the parties’ burdens. The emphasis throughout the dissent is on the necessity of plaintiffs proving a current condition of intentional segregation before any burden shifts to the school district. Although the revised dissent has removed a number of its prior references to “intentional” when discussing “current condition of segregation,” and contends that it has not misapplied the burden, the tenor of the current version of the dissent belies this assertion. See Dissent at 892 (“In a former de jure system, plaintiffs may establish the prima facie case by proving that there is a current condition of intentional segregation”) (emphasis added); id. at 904 (“a plaintiff may satisfy his initial burden of proof by relying upon evidence of ‘recent and remote intentionally segregative actions’ of the school board”) (emphasis added); id. at 917 (“This court misses the mark if it is implying that intent is not relevant in this ease.”); id. at 920 (“intent, whether proven by direct or circumstantial evidence, remains an essential element.”); id. at 920-21 (“It is clear that to sustain the presumption, the plaintiffs were required to prove ‘a current condition of segregation from intentional state action.’ ”) (emphasis added); id. at 952 (“The requirement of a current condition of segregation resulting from past or present segregative intent (as opposed to segregation resulting from voluntary demographic change), prior to the operation of the presumption, allows a school system to redeem itself.”) See also Dowell v. Board of Educ., 890 F.2d 1483, 1519 (10th Cir.1989) (Baldoek, J., dissenting) (“To understand the problems with this court's approach, it is necessary to understand how the burden of proof is allocated before a school district becomes unitary. In a system that was statutorily or officially dual, plaintiffs may establish the prima facie case by proving that there is a current condition of intentional segregation; that the de jure system or its vestiges remain or were reestablished in part of the school system.”) (emphasis added). On the contrary, however, once a school system has been declared unconstitutional because of the existence of de jure segregation, “[u]ntil the ... School System achieves unitary status, official action that has the effect of perpetuating or reestablishing a dual school system violates the defendants’ duty to desegregate.” Pitts v. Freeman, 755 F.2d 1423, 1427 (11th Cir.1985) (emphasis in original); see also, e.g., Morgan v. Nucci, 831 F.2d 313, 329 (1st Cir.1987) (“[T]he fact that a particular school policy or program may be ‘racially neutral,’ in that it no longer reflects discriminatory animus, does not prove that the effects of prior discrimination have been purged”). Even the dissent in Dayton II recognized that “the affirmative duty renders any discussion of segregative intent after 1954 gratuitous.” 443 U.S. at 542-43, 99 S.Ct. at 2982-83. The dissent falls into this error by viewing this case as one of initial liability. The cases the dissent relies on for its statements about plaintiffs’ need to prove intentional segregation are all cases describing a plaintiff’s duty to establish de jure segregation in the first instance. See, e.g., Columbus Bd. of Educ. v. Penick, 443 U.S. 449, 99 S.Ct. 2941, 61 L.Ed.2d 666 (1979) (dissent at 892, 903-904, 911, 917); Keyes (dissent at 892, 903-904, 919, 920-21). This is not such a case. As in Swann, plaintiffs here are alleging that a school system which has already been declared unconstitutional in earlier years has never fulfilled its affirmative duty to eradicate the effects of that segregation. Under these circumstances, plaintiffs need only show that current racial disparities exist, not that such disparities are the result of current intentional segregation on the part of the school board. See Swann, 402 U.S. at 26, 91 S.Ct. at 1281. This is not a liability case in which plaintiffs must prove that the school board has committed unconstitutional acts; that was established in 1954. Where a plaintiff has established segregation in the past and the present, it is “entitled to the presumption that current disparities are causally related to prior segregation, and the burden of proving otherwise rests on the defendants.” School Board of the City of Richmond v. Baliles, 829 F.2d 1308, 1311 (4th Cir.1987); see also Dayton II, 443 U.S. at 536, 99 S.Ct. at 2978 (systemwide nature of de jure schools in 1954 “furnished prima facie proof that current segregation ... was caused at least in part by prior intentionally segregative official acts [and] judgment for the plaintiffs was authorized and required absent sufficient countervailing evidence by the defendant school officials.”); Keyes, 413 U.S. at 211 n. 17, 93 S.Ct. at 2699 n. 17 (after de jure segregation is established, “the burden becomes the school authorities’ to show that the current segregation is in no way the result of those past segregative actions.”); Vaughns v. Board of Educ., 758 F.2d 983, 991 (4th Cir.1985) (same). This presumption ensures that subconscious racial discrimination does not perpetuate the denial of equal protection to our nation’s school children. A focus on provable intent alone would deny a remedy to too many Americans. The dissent asserts that under this view of the law, liability in this case would be frozen as of 1954 and “we merely would decree a remedy based upon the failure of the school board to have absolute racial balance at every school and much of this court’s opinion ... would be superfluous.” Dissent at 894. Of course, liability is not frozen; it just remains until the school board, not the plaintiffs, bears the burden of proving that current racial disparities in the school system are not the result of the prior segregated school system. Contrary to the district court’s apparent conclusion, see 671 F.Supp. at 1297, remoteness in time does not make past intentional acts less intentional. See Dayton II, 443 U.S. at 535-36, 99 S.Ct. at 2977-78; Keyes v. School Dist. No. 1, 413 U.S. 189, 210-11, 93 S.Ct. 2686, 2698-99, 37 L.Ed.2d 548 (1973). The passage of time merely presents an opportunity for a school district to show that the presumptive relationship between the de jure system and the current system is so attenuated that there is no causal connection. See id. at 211, 93 S.Ct. at 2699. What the school district has done to integrate is crucial in determining whether the causal link between the prior segregation and the current disparities has been severed. The district may carry its burden by showing that it has acted affirmatively to desegregate. Absent such proof, the court must presume that current segregation is the result of prior intentional state action. A showing that the school district has not promoted segregation and has allowed desegregation to take place where natural forces worked to that end is insufficient. The ultimate test of what the school district has done is its effectiveness, most significantly its effectiveness in eliminating the separation of white and minority children. While a district is not always required to choose the most desegregative alternative when it selects a particular option, the result of the sum of the choices made by the district must be to desegregate the system to the maximum possible extent. Furthermore, the school district may “not ... take any action that would impede the process of disestablishing the dual system and its effects.” Dayton II, 443 U.S. at 538, 99 S.Ct. at 2979. One choice frequently made by school districts, and the one made in Topeka, is to use a neighborhood school plan as the basis for student assignment. Neighborhood schools are a deeply rooted and valuable part of American education. To the extent that neighborhoods are themselves segregated, however, such plans tend to prolong the existence of segregation in schools. Thus, they must be carefully scrutinized. They are not “per se adequate to meet the remedial responsibilities of local boards.” Davis, 402 U.S. at 37, 91 S.Ct. at 1292; see United States v. Board of Educ., Indep. School Dist. No. 1, Tulsa County, 429 F.2d 1253 (10th Cir.1970). Neighborhood school plans must be both neutrally administered and effective. A plan that is administered in a scrupulously neutral manner but is not effective in producing greater racial balance does not fulfill the affirmative duty to desegregate. It is equally important that a plan’s neutrality be more than surface-deep. We have specifically held that when minorities are concentrated in certain areas of the city, neighborhood school plans may be wholly insufficient to fulfill the district’s affirmative duty to eliminate the vestiges of segregation. Tulsa County, 429 F.2d at 1258-59. Even when neighborhood school plans hold the promise of being effective, courts must recognize that the school district’s choices on such questions as where to locate new schools, which schools to close, how to react to overcrowding or underutilization, and what transfer policy to offer, all have obvious impact on the school attendance boundaries the district can draw under a neighborhood school plan. If these choices are not made with an eye toward desegregation, a neighborhood school plan may “further lock the school system into a mold of separation of races.” Swann, 402 U.S. at 21, 91 S.Ct. at 1278. Ultimately, whether the use of a neighborhood school plan in a particular case is consistent with a school district’s duty to desegregate turns on whether the “school authorities [have made] every effort to achieve the greatest possible degree of actual desegregation taking into account the practicalities of the situation.” Davis, 402 U.S. at 33, 91 S.Ct. at 1290. Contrary to the dissent’s suggestion, dissent at 897, a school district which chose a neighborhood school system in 1954 is not insulated from a later contention that neighborhood schools did not result in desegregation. “A school system is not ... automatically desegregated when a constitutionally acceptable plan is adopted and implemented, for the remnants of discrimination are not readily eradicated.” Ross v. Houston Indep. Sch. Dist., 699 F.2d 218, 225 (5th Cir.1983). Actions the school district has not taken are also relevant in considering what the district has done. A school district which has not made use of such classic segre-gative techniques as gerrymandering, discriminatory transfer policies, and optional attendance zones is more likely to have fulfilled its duty to desegregate than a district that has done so. Similarly, a school district that has made use of the various techniques available to encourage voluntary desegregation is more likely to have fulfilled its duty than one that has not. Such techniques may include, for example, the establishment of magnet schools and vigorous official encouragement of desegregative transfers. Finally, objective proof of the school district’s intent must be considered. How a district lobbies its patrons and government agencies on issues that affect desegregation, whether it seeks and then heeds the desegregation recommendations of others, and the cooperativeness of the district in complying with court orders, for example, bear on the manner in which the district has shaped the current conditions in the school district. C. Maximum Practicable Desegregation What more can and should be done, if anything, is the final component in a determination of unitary status. Essentially, a defendant must demonstrate that it has done everything feasible. Courts must assess the school district’s achievements with an eye to the possible and practical, but they must not let longstanding racism blur their ultimate focus on the ideal. In most unitariness cases, the school district has been implementing a court-approved desegregation plan under active court supervision. The question is usually whether closer adherence to the plan is practical or whether the plan has achieved its objectives. The district court in such cases has been intimately involved with the process of desegregation and is well aware of the obstacles it faces. The court can thus make an informed judgment on the possibilities of further desegregation. Where the school district has complied with the desegregation plan to the best of its ability, and has done what can be done in spite of the obstacles in its way, it is reasonable to conclude that no further desegregation is feasible. The present case is one of those rare ones in which the unitariness determination is not directly tied to the execution of a particular desegregation plan. In such a case, the consideration of whether further desegregation is practicable must include the obstacles that are likely to stand in its way, and whether they may be circumvented without imperiling students’ health or the educational process. See Swann, 402 U.S. at 30-31, 91 S.Ct. at 1282-83. Where there are no significant barriers to desegregation, or such barriers as exist may be overcome without undue hardship, further desegregation is practicable. See id. at 28, 91 S.Ct. at 1282 (mere awkwardness or inconvenience is no barrier to carrying out desegregation plan). In sum, when a school system was previously de jure, a plaintiff bears the burden of showing that there is a current condition of segregation. It may do so by proving the existence of racially identifiable schools. The school district must then show that such segregation has no causal connection with the prior de jure segregation, and that the district has in fact carried out the maximum desegregation practicable for that district. We now apply these legal principles to Topeka. V. THE FINDING OF UNITARINESS Because Topeka’s schools formerly operated under a system of de jure segregation, “[t]he board’s continuing obligation ... [has been] ‘to come forward with a plan that promises realistically to work ... now, ... until it is clear that state-imposed segregation has been completely removed.’ ” Columbus Board of Educ. v. Penick, 443 U.S. 449, 459, 99 S.Ct. 2941, 2947, 61 L.Ed.2d 666 (1979). Prior to this case, no court had pronounced the Topeka school system unitary; hence, this duty never dissipated. The district court concluded, however, that the effects of de jure segregation have been eliminated in Topeka. On appeal, plaintiffs attack this determination. A. Burden of Proof Plaintiffs argue initially that the district court improperly required them to prove intentional discriminatory conduct on the part of the school district over the course of the decades instead of according them the benefit of a presumption that current segregation stems from the prior de jure system. Plaintiffs quote a number of sentences from the district court’s opinion as support for their argument that the court placed on them the burden of proof on intent. Brief for Plaintiffs-Appellants at 27. The court itself expressed some confusion as to the proper burden of proof. 671 F.Supp. at 1295. We have considered both these citations and the tenor of the district court’s opinion as a whole, and we are convinced that the court focused too greatly on the school district’s lack of discriminatory intent. Although the percentage of minority students in Topeka is lower than in other cities involved in desegregation cases and consequently the statistics alone do not appear as egregious, we are persuaded that this overemphasis on the school district’s intent led the court to make the same errors as did the district court in Dayton II. It failed “to apply the appropriate presumption and burden-shifting principles of law.” Brinkman v. Gilligan, 583 F.2d 243, 251 (6th Cir.1978), aff'd sub nom. Dayton Board of Education v. Brinkman, 443 U.S. 526, 99 S.Ct. 2971, 61 L.Ed.2d 720 (1979). The district court made the following findings: that the neighborhood school attendance boundaries drawn in 1955 had the effect of maintaining segregation; that the construction of new schools since that time had the effect of “promot[ing] racial separation”; that the reassignment of students from previous de jure schools to adjacent schools with higher-than-average percentages of minority students had the effect of increasing those percentages; and that the assignment of faculty had the effect of placing minority faculty disproportionately at schools with higher-than-average minority student percentages. 671 F.Supp. at 1300, 1301, 1304-05. It is clear from the court’s other findings that the school district’s use of space additions, its siting of Topeka West high school, its drawing of attendance boundaries, and its failure to adopt various reorganization plans did not further the process of desegregation. Id. at 1298-1301, 1308-09. Nevertheless, the court’s discussion of most of these aspects of Topeka’s history ends with the conclusion that because these actions were not taken with the intent to discriminate and were consistent with a “race-neutral” neighborhood school plan, they did not promote segregation, The court evidently believed that if these two criteria, i.e., no intent to discriminate and consistency with a race-neutral neighborhood school plan, were met, the school district’s actions would pass constitutional muster. The Supreme Court has made clear, however, that a “race-neutral” neighborhood school policy is not sufficient where it fails to remedy de jure segregation: “Absent a constitutional violation there would be no basis for judicially ordering assignment of students on a racial basis. All things being equal, with no history of discrimination, it might well be desirable to assign pupils to schools nearest their homes. But all things are not equal in a system that has been deliberately constructed and maintained to enforce racial segregation. The remedy for such segregation may be administratively awkward, inconvenient, and even bizarre in some situations and may impose burdens on some; but all awkwardness and inconvenience cannot be avoided in the interim period when remedial adjustments are being made to eliminate the dual school systems. "... ‘Racially neutral’ assignment plans proposed by school authorities to a district court may be inadequate; such plans may fail to counteract the continuing effects of past school segregation resulting from discriminatory location of school sites or distortion of school size in order to achieve or maintain an artificial racial separation. When school authorities present a district court with a ‘loaded game board,’ affirmative action in the form of remedial altering of attendance zones is proper to achieve truly non-discriminatory assignments. In short, an assignment plan is not acceptable simply because it appears to be neutral.” Swann, 402 U.S. at 28, 91 S.Ct. at 1282 (emphasis added). While we agree with the district court’s findings that the current school administration is not presently acting with discriminatory intent — indeed, there is evidence that the present school board has some commitment to desegregation — we are persuaded that the court failed adequately to weigh the conduct of the school district for the past thirty years, and the current effects of that conduct. The court erred by limiting the school district’s burden merely to showing that it had nondiscriminatory reasons for acting as it did. As thirty years of desegregation law have made clear, the Constitution requires more than ceasing to promote segregation. See part IV supra. “[T]he measure of the post-Brown I conduct of a school board under an unsatisfied duty to liquidate a dual system is the effectiveness, not the purpose, of the actions in decreasing or increasing the segregation caused by the dual system.” Dayton II, 443 U.S. at 538, 99 S.Ct. at 2979. A lack of intent to discriminate is therefore insufficient. “In short, [a student] assignment plan is not acceptable simply because it appears to be neutral.” Swann, 402 U.S. at 28, 91 S.Ct. at 1282. Mere adherence to a race-neutral but ineffective neighborhood school plan is insufficient. In general, any course of action that fails to provide meaningful assurance of prompt and effective disestablishment of a dual system is unacceptable. Wright v. Council of City of Emporia, 407 U.S. 451, 460, 92 S.Ct. 2196, 2202, 33 L.Ed.2d 51 (1972). The district court did not heed this mandate. While it did find that the school district had taken some actively desegregative actions, we are convinced that the court’s overall conclusion as to unitariness was fatally infected by the inadequacy of the burden of proof standard to which it held the school district. B. The Evidence In order to assess the district court’s finding of unitariness under the appropriate burden of proof and the general principles we have outlined, we turn to a more specific review of the record. As a general matter, it is important to note that much of the record evidence consists of statistics and other undisputed facts. Our differ-enees with the district court lie mainly in how the essentially undisputed facts are assessed in light of the school district’s mandate to dismantle the segregated school system. We believe that the district court’s finding of unitariness is flawed by the undue deference it gave to the school district’s neighborhood school policy and by the court’s failure to give proper weight to its own findings that certain actions and omissions by the school district had a seg-regative effect. Cf. Diaz v. San Jose Unified School Dist., 733 F.2d 660, 674 (9th Cir.1984) (en banc) (“In making its determination in respect to the Board’s intent, the district court erred in failing to give weight to the cumulative impact of the evidence”; district court’s findings that defendants acted without segregative intent held clearly erroneous). 1. Current Condition of Segregation in Topeka The district court found that “there are disparities in the racial makeup of various schools’ enrollments,” and that “[pjlaintiffs have demonstrated that in general there are a greater than average number of minority faculty and staff in schools with a greater than average number of minority students.” 671 F.Supp. at 1295, 1304. Like most courts, however, the district court did not discuss separately the issues of current segregation and the causal con-neetion between that segregation and the prior de jure segregation. As we have pointed out, the simplest and most compelling evidence of segregation is the presence of predominantly one-race schools. In a system such as Topeka’s, however, in which the minority student population is relatively small, there may be a number of primarily white schools even though minority students are spread through a significant number of other schools. In such a system, it is the concentration of minority students that is usually the hallmark of discrimination. Because the significance of mostly white schools is therefore not necessarily as great in a mostly white system as it would be in a system with a heavy minority population, we focus on the broader form of racial identifiability discussed in part IV A above. In support of their argument that there is currently segregation in Topeka, plaintiffs point primarily to student assignment, and faculty and staff assignment. We consider each in turn, and then together. a. Student Assignment Each of the experts who testified at trial used a different standard for determining whether a school was racially identifiable in student assignment. Plaintiffs’ main experts, Mr. Lamson and Dr. Foster, each used standards that took the percentage of black or minority students actually enrolled in the elementary or secondary schools (26% in 1985), and then added and subtracted some number to obtain a range within which they did not consider schools to be racially identifiable on the basis of student assignment alone. Their methods differ to some extent, but for 1985 either method leads to a range of 11-41% (26% plus or minus 15%). The school district’s primary expert on this issue, Dr. Armor, used an absolute rather than a relative standard. In his view, desegregated schools should optimally have 20-50% minority students, regardless of the percentage of minority students in the system. Dr. Armor also allowed a variance, which resulted in a range of acceptability of 10-60%. As plaintiffs point out, under any of these methods there are schools in Topeka that are racially identifiable by student assignment. Even under the most generous of these numerical standards, proposed by the school board’s expert, there are six elementary and three secondary schools that are racially identifiable by student assignment. Notwithstanding the dissent’s view that the statistics regarding the percentages of minorities in the racially overbalanced schools do not add up to a current condition of segregation, we believe the figures speak for themselves. See supra at 856-58. In this connection, the charts in the dissent showing the racial inventories over the years at Belvoir, Hudson, Highland Park North, Lafayette, Quinton Heights, and Lowman Hill speak more eloquently about the current condition of segregation in Topeka than words ever could. See dissent at 936 n. 43; 938 n. 44; 939 n. 45; 939-40 n. 46; 941-42 n. 47; 946 n. 51. b. Faculty and Staff Assignment To determine racial identifiability by faculty/staff assignment, plaintiffs again used a standard based on the actual percentage of minority employees and a range of a few percentage points above and below that number. The school district contested the accuracy of plaintiffs’ standard but presented no alternative one. We do not adopt plaintiffs’ standard, but instead evaluate the data on its face. In 1985, the percentage of minority faculty/ staff in the Topeka school system was 11.2% for the elementary schools and 12.65% for the secondary schools. In the elementary schools, the percentage of minority faculty/staff at individual schools ranged from 0% to 33.3%. Nine schools had less than 5% minority faculty/staff, and two had more than 25%. In the secondary schools, the percentage ranged from 2.5% to 24.7%. One school had less than 5% minority faeulty/staff, an additional three schools had less than 10%, and one had more than 20%. Faculty/staff data have been kept only since 1973 and, except for 1981, that data does not distinguish between faculty and staff. Rec., ex. vol. IV, at 263-68. Faculty/ staff includes managerial personnel at both the school and district level, teacher aides, clerical/secretarial employees, skilled and technical employees, and service workers, as well as teachers and other professional staff. The distinction between facul- ty and staff is particularly relevant because the percentage of minority employees has always been lower than the minority student population, and has fallen steadily at the elementary level over the period such data was kept. Moreover, minorities are represented more heavily in staff positions than in faculty positions. In 1985, for example, district-wide statistics showed that 11.3% of elementary teachers and 8.0% of secondary teachers were minorities, while 19% of teacher aides and 20% of service workers were minorities. Rec., vol. IV, at 268. Any one faculty/staff person listed at any one school is thus more likely to be a teacher aide or service worker than a teacher. We recognize that the small number of faculty and staff at any one school means that the presence or absence of one minority employee may have a considerable effect on the school’s minority percentage. Nevertheless, we see no obviously neutral reason why McClure elementary school has no minority employees among its 25 faculty/staff and Topeka West high school has 3 among 120, while Avondale East elementary school has 10 minority faculty/staff out of a total of 31 employees and Robinson middle school has 12 out of 49. c. Factors considered together Because faculty/staff assignment is largely within the control of the school district, it is a potent tool for demonstrating that the district does or does not itself identify certain schools as white or minority. It also provides an opportunity for undoing some of the harm of segregated student assignments, because both white and minority students may benefit from the presence of minority role models. See Washington v. Seattle School District, No. 1, 458 U.S. 457, 472, 102 S.Ct. 3187, 3196, 73 L.Ed.2d 896 (1982) (“white as well as Negro children benefit from exposure to ethnic and racial diversity in the classroom”). Conversely, if the district disproportionately assigns minority faculty/staff to those schools with the highest percentages of minority students, the district is in effect reinforcing the identification of particular schools as white or minority. This practice of disproportionate assignments also reinforces the irrational notion that minority teachers are inferior and not fit to teach white children. In Topeka, although the correlation is not completely uniform, see 671 F.Supp. at 1305, there is a clear pattern of assigning minority faculty/staff in a manner that reflects minority student assignment. This correlation is fatal to the school district’s effort to show a lack of current segregation. Both student assignment and faculty/staff assignment can be expected to vary from school to school, the former because of population distribution, and the latter, to a lesser extent, because of differing teacher credentials. When they vary together, as they do in Topeka, leading to schools that are noticeably more white or more minority in both students and faculty, it is difficult to posit a neutral explanation. The school district has not attempted to provide one. Moreover, when we look beyond the numbers, we find that the schools that are marked as white or minority by their students and faculty/staff are also so marked by their geography, the residential population in their attendance areas, and by their history. Of the six racially identifiable elementary schools detected by Dr. Armor’s method, five are now and always have been attended almost exclusively by white students. They are located on the western and northwestern edges of the school district, areas with mostly white populations. The same is true of the three secondary schools. See infra part V B(2)(c)(vii). The one remaining elementary school, Belvoir, is located on the eastern edge of the school district. The area has long been inhabited by a significant minority population, and the school’s student population is now and has been for over twenty years more than half minority. See infra part V B(2)(c)(i). Finally, the correlation between student assignment and faculty/staff assignment is not a one-year fluke. The same correlation has existed throughout the course of this litigation. See infra part V B(2)(b)(ii). Considering all of these factors together, there is sufficient evidence to support plaintiffs’ contention that there is a current condition of segregation in Topeka. 2. The Causal Link Between De jure Segregation and the Current Condition of Segregation Brown I established that the Topeka school system was one of de jure segregation. Because there is a current condition of segregation, we turn our attention to the causal link between these two conditions of segregation, which must be assessed in light of the burden and factors set out in part IV B, supra. We are convinced that the school district failed to meet its burden of showing the absence of this link. This failure, which the district court did not see because it failed to impose on defendants the proper burden of proof, is the key to our reversal. Timing is central to an assessment of the Topeka school district’s actions. After what was described as a “good faith” beginning, Brown, 139 F.Supp. at 470, the course the school district followed in the late 1950s and early 1960s may fairly be characterized as segregative. The decade from 1956 to 1966 is important because it established a framework from which the school district subsequently deviated very little. A period of quiescence then followed, during which the system was simply administered as it stood. It was not until HEW threatened to withhold federal funds in the mid-1970s that the school district undertook some positive action to desegregate its schools. After that brief flurry of action, the school district again turned its attention elsewhere, but to its good fortune the oft-maligned forces of demography began to work in its favor. Two things are apparent from the record. First, Topeka has largely acted as if it had fulfilléd its duty to desegregate at the conclusion of the four-step plan implemented in the 1950s. Second, although Topeka’s schools have in fact become less segregated in the last decade, this lessening of segregation is due in part to forces beyond the control of the school district. Moreover, those desegregative actions which the school board did undertake were primarily the result of pressure from the federal government, or were instituted after this lawsuit was filed. Although its record is better than that of many other school districts, Topeka has engaged in voluntary desegregation with little enthusiasm. a. The general pattern in each decade i. The mid-50s to mid-60s This period was one of significant change in the Topeka school district. Most notably, the district expanded greatly with several city-imposed annexations at the end of the 1950s, the beginning of a spurt in population growth and shift to the newly annexed areas, and the school district’s consequent opening of new schools in this outer white part of Topeka. As the white population moved outwards, the inner city population became increasingly heavily minority, and inner city schools were closed. The mid-60s found the Topeka school system still heavily segregated. While the numeric polarization between schools had decreased to some extent systemwide, and minority students were somewhat less concentrated, the number of schools serving primarily white children had increased. Geographic polarization also increased, as a result of the building of so many primarily white schools on the outer edges of the district. Plaintiffs introduced evidence tending to show that the school district’s use of portable classrooms and optional attendance zones served to maintain segregation by concentrating students of one race at certain schools. The school district’s expert, Dr. Clark, conceded that his study of changes in attendance zone population because of changed attendance boundaries led him to conclude that one such boundary change might have had seg-regative effects not explainable solely by demographic shifts. We have no doubt that during this period the school district in fact maintained and perhaps promoted a segregated system by current standards. Moreover, the system that existed after the wave of school openings and closings ended, i.e., the location of schools and the race of their students, formed the basis for the current elementary system. Therefore, while the school district should not be judged primarily by actions now twenty or more years in the past, neither can those actions be ignored. ii. Mid-60s to Mid-70s This period was one of quiescence in the school district. Enrollment in the Topeka school system peaked in 1969, substantially ending the need for new school buildings. Outer Topeka continued to grow in white population, particularly in the western part of the city. Minority population began to spread out of its highly concentrated central areas into eastern Topeka. The only significant change in the school system at the end of this period was that the number of virtually all-white schools dropped. At the elementary level, 19 out of a total of 35 elementary schools were virtually one-race in 1966; 13 out of a total of 34 were virtually one-race in 1974. The change at the secondary level was even less: from 6 out of 14 schools in 1966, to 5 out of 15 schools in 1974. This change took place primarily in schools on the outskirts of the southeastern part of Topeka, the area into which minorities were spreading. The school district’s conduct during this period can thus be summarized as letting demographic forces work without interference or encouragement. This also means that schools already heavily minority were allowed to increase in minority population. It is apparent that while Topeka did not promote a segregated school system during this period, it maintained the system then in effect notwithstanding its affirmative duty to eliminate segregated schools. iii. Mid-70s to the present In 1974, the HEW compliance action began the third phase of the Topeka school system since Brown I. At the elementary level, HEW cited unequal facilities for minority and white children as well as “stu- dent racial compositions not consonant with a unitary plan.” Five elementary schools were specifically listed as having “substantially disproportionate minority student compositions clearly the result of a former dual pattern of operation.” At the secondary level, HEW found that the junior high schools attended by most minority students were inferior in facilities to those schools attended largely by white students. In addition, the district’s transfer plan was criticized. The Board denied that the district was in noncompliance and obtained an injunction against further HEW administrative proceedings. Nevertheless, the Board agreed to take “administrative steps to assure a more perfect unitary school district.” It developed and implemented two plans largely approved by HEW. These plans had some success. At the end of the reorganization, there were no 90 + % minority elementary schools, the attendance boundaries of two 90 + % white schools had been redrawn so that they were no longer one-race, and a third one-race white school had been closed. At the secondary level, two heavily minority and on
