This memorandum reports results of an analysis designed to obtain answers to the following questions: (1) How does the Overall High School Average compare with Converted Rank in Class as a predictor of Freshman Year Grades in college? and (2) Will more detailed information provided by analysis of high school records by subject help to improve accuracy of forecasts of college grades or to improve understanding of factors associated with performance in college? The study is based on students who entered CRC-member colleges in September 1966, who earned a freshman year average during academic 1966-67, and for whom scores on the Scholastic Aptitude Test, the average of CEEB achievements, coverted rank, a cumulative high school average, and averages in high school English, languages, mathematics, sciences, and social studies were available. The results indicate that the overall high school average, as compared with the Converted School Rank, yields higher simple correlations with freshman year average in 10 of 16 comparisons, and approximately equal or only slightly lower coefficients in the remainder of comparisons, and when combined with three standardized test variables, yields higher multiple correlations with freshman year average in 9 of 16 comparisons, and approximately equal or only slightly lower coefficients in the remainder of cases. When averages in five subjects are treated rather than the cumulative high school average, results indicate that the more detailed information about the high school record shows promise of improving predictions of freshman year performance and has value from the point of view of gaining insight into the aspects of the high school record most closely associated with college freshman performance.
