The purpose of this study was to determine the usefulness of 2 measures of student quality, high school percentile ranks and ACT composite standard scores, in predicting the first-year academic success of freshmen entering Wisconsin State University (WSU) at Stevens Point. The average high school percentile rank for the 2,172 entering freshmen in the fall of 1968 was 61.3. The 424 students who were dropped for academic failure after 2 semesters had an average high school percentile rank of 43.7; students remaining in college had an average percentile of 65.6. ACT standard scores were available for 2,068 of the freshmen; the average ACT score was 21.28. Students suspended for academic reasons after 2 semesters averaged 19.40, and those remaining averaged 21.72. It was concluded that the high school percentile rank is closely related to college success and is a good predictor of student quality, but that ACT scores are limited predictors (1 student with an ACT score of 7 survived) and should not be used as a single criterion for entrance to WSU. These findings were compared with others on WSU graduates in 1968 (582) and 1969 (609). The average high school percentile rank for the 1968 graduates was 69.4, and ACT scores ranged from 11 to 30, with a mean of 21.84; nearly 81.1% of the 1969 graduate ranked in the upper half of their high school class, and available ACT scores ranged from 8 to 30, with a mean of 22.10. These findings seem to support the conclusions of the study. (WM)
