Performance on The Scholastic Aptitude Test-Verbal (SAT-V) and Mathematical (SAT-M), the applicant's rank in class or Converted Secondary School Rank (Rank), and the applicant's general level of measured secondary school achievement as indicated by the Average of CEEB Achievement Tests (ACH AV) has been used by Vassar College as admissions measures and as predictors of freshman-year performance. Six validity studies involving data for classes entering Vassar during the period 1963 through 1971 reveal a relatively consistent pattern of relationships between Freshman Average Grade and the admissions tests scores. In each study, the best single indicator of probable performance during the freshman year has been either the CEEB Achievement average of the Converted School Rank. The SAT-V was the third best single indicator, and the SAT-M provided information of least value. However, the combination of scores provides a better indication of probable performance than any single score. The most recent validity study of the scores of Vassar's Class of 1975 (324 women and 170 men) confirm the findings of the previous six studies. The findings of this study also showed that the combination of all four academic predictors is slightly higher for women than for men, and the aptitude measures tend to be more closely associated with freshman grades among the women than among the men. Eight tables provide the data for the various studies. (DB)
