Many schools have diverse student bodies.
Only some schools achieve that result through the use of dual admissions systems. A question arises as to why certain schools now find themselves in legal difficulty because of an over-reliance on race in making admissions decisions. Generally, schools that rely heavily on standardized test scores also tend to rely heavily on racial preferences. Schools that use standardized test scores in an automatic or mechanical way to sort applicants are under especially heavy pressure to use racial preferences. That's because there are long-standing, significant disparities in the average standardized test scores of different racial groups.
