This report presents the results of a large-scale national validity study of the SAT®. In March 2005, the College Board introduced a revised SAT, with an additional section in writing and minor changes in content to the verbal and mathematics sections. The first full cohort of students taking this test completed their first year of college in May/June 2007. This report documents the methods undertaken to recruit institutions to participate in the study; the procedures for gathering, cleaning, and aggregating data; and the statistical corrections and analyses applied to the data and the results of those analyses. The report concludes with a discussion of the results in light of prior SAT validity studies and a description of future SAT validity research studies. The results show that the changes made to the SAT did not substantially change how well the test predicts first-year college performance. Across all institutions, the recently added writing section is the most highly predictive of the three individual SAT sections. As expected, the best combination of predictors of first-year college grade point average (FYGPA) is high school grade point average (HSGPA) and SAT scores. The College Board continues to encourage institutions to use both measures when making admissions decisions. Two appendices are included: (1) Participating Institutions; and (2) Characteristics of Participating Institutions.
