Available empirical data relating to the effects of changes in freshmen admissions at the university are summarized. Included are the data concerning the construction of an admissions index based on core high school GPA and verbal and quantitative test scores. Findings are that the arbitrary weighting of one-third test scores to two-thirds HS grades was nearly optimal; that equal weight of verbal and quantitative components was optimal. The second set of studies reported here imposed the new standards on UW applicants for fall 1973. Nearly all applicants had completed distribution requirements before their senior year and their admissions index distribution was identical to that of the fall 1970 entrants. Finally, the contribution of elective high school course work (in particular art and music) was explored. Electives did not improve grade prediction, and among the elective areas only business and home economics appeared significantly correlated with university success. (Author)
