Abstract Objective The aim of the present study is to determine whether 2 current admission criteria, the perceptual ability test (PAT) and the manual dexterity test (MDT) can predict success in dental school within the Université de Montréal population. Methods A retrospective cohort study was conducted using the records of 854 students who graduated between 2005 and 2015. For each student, PAT and MDT scores were compared to 5 preclinical and 3 clinical classes using the Pearson correlation coefficient and regression models. T‐tests were used to compare students above and below a 5‐point increase in cut‐off scores (PAT = 15, MDT = 10). Results The strongest relationship was found to be between PAT and preclinical scores (r = 0.329, P < 0.01). The regression analysis determined that gender, PAT and MDT predicted more of the variability of preclinical (12.7%) than of clinical scores (2.7%). Students scoring ≥10 on the MDT performed better in preclinical and clinical courses, and those scoring ≥15 on the PAT performed better in preclinical courses. However, when comparing these students to the entire group, only those scoring ≥15 on PAT differed from the group's average for preclinical scores ( P = 0.029). Conclusion These findings suggest the PAT and MDT have some power in predicting success in preclinical, and to a lesser extent clinical courses, and supports their use as criteria in the admissions process. There is some evidence that suggests that increasing the cut‐off score may decrease the number of students with difficulties in preclinical courses.
