It is imperative to achieve diversity in Higher Education. With affirmative action policies under fire, it is becoming difficult to enroll a diverse student body. Many critics see standardized tests, and the SAT in particular, as contributing to the problem. This paper reviews research on such criticism, about suggested alternative approaches, and regarding recommendations on how to improve the current situation. In general, this review finds little evidence against a judicious use of the SAT. Also, alternative approaches such as percent plans or abolishing the SAT have had little success in increasing diversity. However, most specialists agree that a comprehensive approach to college admissions is needed.
