The relation of ninth grade test scores to twelfth grade test scores and high school rank

Abstract

From a population of high school students who had been tested in state-wide programs at the ninth and twelfth grade levels, a sample of 2185 was used to compute correlations between performance at these scholastic levels. At the ninth grade the tests were the ACE (Highschool Edition) and the Cooperative English Test (Form Y); at the twelfth grade level the tests were the ACE (College Edition) and the Cooperative English Test (Form S). HS percentile ranks were also computed for the Ss. The correlation between different forms of the same test was .8, for each test. The correlations between ACE forms and the Coop forms were .7 or higher. HSR correlated .63 with ninth grade ACE score, .71 with ninth grade English.
