Title:
Affirmative_action_in_the_United_States

Context:
In the US, a prominent form of racial preferences relates to access to education, particularly admission to universities and other forms of higher education. Race, ethnicity, native language, social class, geographical origin, parental attendance of the university in question (legacy admissions), and/or gender are sometimes taken into account when the university assesses an applicant's grades and test scores. Individuals can also be awarded scholarships and have fees paid on the basis of criteria listed above. In 1978, the Supreme Court ruled in Bakke v. Regents that public universities (and other government institutions) could not set specific numerical targets based on race for admissions or employment. The Court said that "goals" and "timetables" for diversity could be set instead.
