SAT UPDATE
• Colleges use the SAT as a way to check against unequal opportunities, variable standards and grade inflation.
• Some colleges use SAT scores for placement and scholarship opportunities.
• SAT scores are only one among many factors that colleges use to make admission decisions.
How Do Colleges Use the SAT®?
*Along with high school grades, the SAT is the best predictor of college success.
The SAT® provides a valid, nationally consistent measure
of what students have learned and how well they apply that knowledge.*

Correlations* of Predictors with First-Year College Grade Point Average
*All correlations have been corrected for restriction of range.Sample size: 159,286 students at 110 colleges and universities in entering class of 2007.
Correlations* of Predictors with Second-Year Cumulative College Grade Point Average
*All correlations have been corrected for restriction in range.Sample size: 80,958 students at 66 colleges and universities. Results are based on institutions in the 2006 cohort that provided second-year data.

High School Grades Shifting Over Time
*Based on four-point system, where A=100Note: 1990 GPAs reflect all Student Data Questionnaire responders, not just SAT® takers. GPAs for 1995-2010 reflect SAT® takers only.
As SAT scores increase, so does the likelihood of a student returning for the second and third year of college.
SAT Scores Identify Students Who Will Return
SAT takers in the class of 2010:
– 42% were minority students– 25% reported that English
was not exclusively spoken at home
– 45% intend to be first-generation, college-bound students
• The SAT is administered by over 6,000 test centers in more than 170 countries!
