What predicts performance in Canadian dental schools?

The task of selecting the best dental applicants out of an extremely competitive applicant pool is a problem faced annually by dental faculties. This study examined the validity of both cognitive and noncognitive factors used for selection to Canadian dental schools. Interest in personality measurement and the prediction offered by personality measures has escalated and may be applied to the selection of dental candidates. Therefore, the study also assessed whether the addition of a personality measure would increase the validity of predicting performance beyond that achieved by an interview and the Dental Aptitude Test. Results suggest that an interview may be useful in identifying specific behavioral characteristics deemed important for success in dental training. Consistent with previous research, results show that the Dental Aptitude Test is a good predictor of preclinical academic success, with prediction declining when clinical components of the program are introduced into the criterion. Results from the personality measure indicated that Openness to Experience was significantly related to aspects of clinical education, although, contrary to expectations, this relationship was negative. A facet of Openness, Ideas, together with Positive Emotions, a facet of Extroversion, improved prediction of performance in clinical studies beyond that provided by the Dental Aptitude Test and the Interview. Implications of the findings are discussed, and recommendations regarding the admission process to Canadian dental programs are offered.
