The study was conducted to examine the predictive validity of scores taken with an extended-time accommodation.

Postsecondary students with learning disabilities who took the SAT I between 1995 and 1998 with extended-time accommodations comprised the sample (n=463). The sample was drawn from students attending 14 postsecondary institutions across 10 different states (U.S.). Additional information describing the postsecondary institutions was reported.

SAT I test scores, and self-reported high school grade point average (HSGPA), were used as the dependent variables to predict first year grade point average (FGPA).

In general, the revised SAT was to be positively correlated with FGPA for students who took the test with extended time accommodations for a learning disability. SAT scores were fairly accurate predictors of FGPA for students with learning disabilities. In the majority of cases when HSGPA was used along with SAT test scores, the predictive validity of FGPA was increased.
