After examining the decline in average scores on the Scholastic Aptitude Test (SAT) from 1963 to the present, it has been suggested that, although SAT scores continue to contribute to effective prediction of college grades, the test may have been overtaken by changes in high school programs that have made the test increasingly less related to the learning that takes place at the secondary school level. Two sets of data are examined: (1) correlations of SAT scores with student reports of class standing for 1971-72 through 1975-76, and (2) correlations of SAT scores with measures of high school performance for groups of students attending colleges participating in the College Board Validity Study Service, for entering classes from 1964 through 1974. The correlations of SAT scores with self-reported class rank are virtually level over the five years studied. The longer-term comparisons using validity study data suggest that the median correlations of SAT verbal or mathematical scores with high school grades may have increased somewhat over the 11 years studied. Therefore, the relationship between SAT scores and high school grades appears to have increased in recent years. (Author/EVH)
