Grade averages and DAT scores as predictors of performance in dental school

Admission into dental faculties is based on preprofessional average, prerequisite average, and DAT scores among other criteria. This study investigated the predictive validity of these variables on success in the Faculty of Dentistry at the University of British Columbia. Data on 312 students admitted between 1969 and 1976 were subjected to multiple regression analyses. Results showed that overall preprofessional average significantly correlated .17 to .29 with nine first- and second-year course grades, .36 with first-year average, and .29 with second-year average. DAT manual average correlated significantly with five course grades from .20 to .36, .20 with second-year average, and .30 with third-year average grades. Chalk carving correlated significantly .20 to .40 with five course grades and .24 with third-year average. It is recommended that overall average and chalk carving be given equal emphasis in the selection process.
