The Law School's educational judgment that such diversity is essential to its educational mission is one to which we defer. The Law School's assessment that diversity will, in fact, yield educational benefits is substantiated by respondents and their amici. Our scrutiny of the interest asserted by the Law School is no less strict for taking into account complex educational judgments in an area that lies primarily within the expertise of the university. Our holding today is in keeping with our tradition of giving a degree of deference to a university's academic decisions, within constitutionally prescribed limits. See Regents of Univ. of Mich. v. Ewing,
474 U. S. 214, 225 (1985); Board of Curators of Univ. of Mo. v. Horowitz,
435 U. S. 78, 96, n. 6 (1978); Bakke,
438 U. S., at 319, n. 53 (opinion of Powell, J.).
We have long recognized that, given the important purpose of public education and the expansive freedoms of speech and thought associated with the university environment, universities occupy a special niche in our constitutional tradition. See, e.g., Wieman v. Updegraff,
344 U. S. 183, 195 (1952) (Frankfurter, J., concurring); Sweezy v. New Hampshire,
354 U. S. 234, 250 (1957); Shelton v. Tucker,
364 U. S. 479, 487 (1960); Keyishian v. Board of Regents of Univ. of State of N. Y.,
385 U. S., at 603. In announcing the principle of student body diversity as a compelling state interest, Justice Powell invoked our cases recognizing a constitutional dimension, grounded in the First Amendment, of educational autonomy: "The freedom of a university to make its own judgments as to education includes the selection of its student body." Bakke, supra, at 312. From this premise, Justice Powell reasoned that by claiming "the right to select those students who will contribute the most to the 'robust exchange of ideas,' " a university "seek to achieve a goal that is of paramount importance in the fulfillment of its mission."
438 U. S., at 313 (quoting Keyishian v. Board of Regents of Univ. of State of N. Y., supra, at 603). Our conclusion that the Law School has a compelling interest in a diverse student body is informed by our view that attaining a diverse student body is at the heart of the Law School's proper institutional mission, and that "good faith" on the part of a university is "presumed" absent "a showing to the contrary."
438 U. S., at 318-319.
As part of its goal of "assembling a class that is both exceptionally academically qualified and broadly diverse," the Law School seeks to "enroll a 'critical mass' of minority students." Brief for Respondents Bollinger et al. 13. The Law School's interest is not simply "to assure within its student body some specified percentage of a particular group merely because of its race or ethnic origin."Bakke,
503 U. S. 467, 494 (1992) ("Racial balance is not to be achieved for its own sake"); Richmond v. J. A. Croson Co.,
488 U. S., at 507. Rather, the Law School's concept of critical mass is defined by reference to the educational benefits that diversity is designed to produce.
These benefits are substantial. As the District Court emphasized, the Law School's admissions policy promotes "cross-racial understanding," helps to break down racial stereotypes, and "enables [students] to better understand persons of different races." App. to Pet. for Cert. 246a. These benefits are "important and laudable," because "classroom discussion is livelier, more spirited, and simply more enlightening and interesting" when the students have "the greatest possible variety of backgrounds."Id., at 246a, 244a.
The Law School's claim of a compelling interest is further bolstered by its amici, who point to the educational benefits that flow from student body diversity. In addition to the expert studies and reports entered into evidence at trial, numerous studies show that student body diversity promotes learning outcomes, and "better prepares students for an increasingly diverse workforce and society, and better prepares them as professionals." Brief for American Educational Research Association et al. as Amici Curiae 3; see, e.g., W. Bowen & D. Bok, The Shape of the River (1998); Diversity Challenged: Evidence on the Impact of Affirmative Action (G. Orfield & M. Kurlaender eds. 2001); Compelling Interest: Examining the Evidence on Racial Dynamics in Colleges and Universities (M. Chang, D. Witt, J. Jones, & K. Hakuta eds. 2003).
These benefits are not theoretical but real, as major American businesses have made clear that the skills needed in today's increasingly global marketplace can only be developed through exposure to widely diverse people, cultures, ideas, and viewpoints. Brief for 3M et al. as Amici Curiae 5; Brief for General Motors Corp. as Amicus Curiae 3-4. What is more, high-ranking retired officers and civilian leaders of the United States military assert that, "ased on [their] decades of experience," a "highly qualified, racially diverse officer corps ... is essential to the military's ability to fulfill its principle mission to provide national security." Brief for Julius W. Becton, Jr. et al. as Amici Curiae 27. The primary sources for the Nation's officer corps are the service academies and the Reserve Officers Training Corps (ROTC), the latter comprising students already admitted to participating colleges and universities. Id., at 5. At present, "the military cannot achieve an officer corps that is both highly qualified and racially diverse unless the service academies and the ROTC used limited race-conscious recruiting and admissions policies." Ibid. (emphasis in original). To fulfill its mission, the military "must be selective in admissions for training and education for the officer corps, and it must train and educate a highly qualified, racially diverse officer corps in a racially diverse setting." Id., at 29 (emphasis in original). We agree that "t requires only a small step from this analysis to conclude that our country's other most selective institutions must remain both diverse and selective." Ibid.
We have repeatedly acknowledged the overriding importance of preparing students for work and citizenship, describing education as pivotal to "sustaining our political and cultural heritage" with a fundamental role in maintaining the fabric of society. Plyler v. Doe,
457 U. S. 202, 221 (1982). This Court has long recognized that "education ... is the very foundation of good citizenship." Brown v. Board of Education,
347 U. S. 483, 493 (1954). For this reason, the diffusion of knowledge and opportunity through public institutions of higher education must be accessible to all individuals regardless of race or ethnicity. The United States, as amicus curiae, affirms that "[e]nsuring that public institutions are open and available to all segments of American society, including people of all races and ethnicities, represents a paramount government objective." Brief for United States as Amicus Curiae 13. And, "[n]owhere is the importance of such openness more acute than in the context of higher education."Ibid. Effective participation by members of all racial and ethnic groups in the civic life of our Nation is essential if the dream of one Nation, indivisible, is to be realized.
Moreover, universities, and in particular, law schools, represent the training ground for a large number of our Nation's leaders. Sweatt v. Painter,
339 U. S. 629, 634 (1950) (describing law school as a "proving ground for legal learning and practice"). Individuals with law degrees occupy roughly half the state governorships, more than half the seats in the United States Senate, and more than a third of the seats in the United States House of Representatives. See Brief for Association of American Law Schools as Amicus Curiae 5-6. The pattern is even more striking when it comes to highly selective law schools. A handful of these schools accounts for 25 of the 100 United States Senators, 74 United States Courts of Appeals judges, and nearly 200 of the more than 600 United States District Court judges. Id., at 6.
In order to cultivate a set of leaders with legitimacy in the eyes of the citizenry, it is necessary that the path to leadership be visibly open to talented and qualified individuals of every race and ethnicity. All members of our heterogeneous society must have confidence in the openness and integrity of the educational institutions that provide this training. As we have recognized, law schools "cannot be effective in isolation from the individuals and institutions with which the law interacts." See Sweatt v. Painter, supra, at 634. Access to legal education (and thus the legal profession) must be inclusive of talented and qualified individuals of every race and ethnicity, so that all members of our heterogeneous society may participate in the educational institutions that provide the training and education necessary to succeed in America.
The Law School does not premise its need for critical mass on "any belief that minority students always (or even consistently) express some characteristic minority viewpoint on any issue." Brief for Respondent Bollinger et al. 30. To the contrary, diminishing the force of such stereotypes is both a crucial part of the Law School's mission, and one that it cannot accomplish with only token numbers of minority students. Just as growing up in a particular region or having particular professional experiences is likely to affect an individual's views, so too is one's own, unique experience of being a racial minority in a society, like our own, in which race unfortunately still matters. The Law School has determined, based on its experience and expertise, that a "critical mass" of underrepresented minorities is necessary to further its compelling interest in securing the educational benefits of a diverse student body.
