The current study examines the relationship between the SAT® College Readiness Benchmark with the outcome of graduation from college in either four or six years. The results indicate that the SAT benchmark is indeed differentiating between those students who graduate within four years and those who do not, as well as between those who graduate within six years and those who do not. The data were further disaggregated by student characteristics of gender, ethnicity, best spoken language, household income, and highest parental education. Even within student subgroups, differences in graduation rates for students who were college ready versus those who did not meet the SAT benchmark persisted. The results from the current study provide additional validity evidence for the use of the benchmark as a measure of college readiness and as a crucial tool in guiding educational interventions and policy that promote college success for all students.
