Here is some background information about affirmative action as well as a few notable court cases.

Affirmative action policies focus on improving opportunities for groups of people, like women and minorities, who have been historically excluded in United States’ society. The initial emphasis was on education and employment. President John F. Kennedy was the first president to use the term in an executive order.

Facts

Supporters argue that affirmative action is necessary to ensure racial and gender diversity in education and employment. Critics state that it is unfair and causes reverse discrimination.

Racial quotas are considered unconstitutional by the US Supreme Court.

The state of Texas replaced its affirmative action plan with a percentage plan that guarantees the top 10% of high-school graduates a spot in any state university in Texas. California and Florida have similar programs.
