Evaluation of applicants to predoctoral dental education programs: review of the literature.

This review finds that college GPA and DAT scores provide dental schools in the United States and Canada with defensible methods for selecting students. College GPA seems the best predictor of academic performance in dental school. The academic average (AA) of the DAT is a better predictor than is the perceptual ability test (PAT), but dental educators who believe that evidence of manual dexterity or perceptual ability must be a part of the admissions decision can find enough supporting evidence to justify doing so. When added to college GPA and the AA, information from the PAT may in fact enhance predictability. There is also evidence, however, that manual skills can be learned during routine dental curricular experiences. Overall, conventional admissions criteria at best account for about 40 percent of the variance in dental school performance, and most of this variance occurs during the early years of the curriculum. Studies are lacking for evaluating criteria that may predict success in admitting students for preferentially addressing current challenges, including achieving diversity of the workforce, ensuring access to care for all, interprofessional health care, ethics and professionalism, filling faculty positions, and conducting needed research. Schools should periodically validate all of their admissions criteria against expected performances and make corresponding adjustments.
