The purpose of this quantitative study was to examine the ability of standardized test scores to predict the performance of students in first-year mathematics courses, and the extent to which these tests displayed differential validity among various subgroups. Using discriminant analysis, it was established that the following percentages of students were correctly classified into passing and not passing groups, using the listed independent variables: a) SAT mathematics scores - 58.6%, b) SAT verbal scores - 50.6%, c) ACT mathematics scores - 54.7%, and d) ACT verbal scores - 56.3%. New predictive models were created using standardized test scores in combination …
