In the clinical stage, however, the mean of critical thinking disposition was 214.07 ± 28.15 which showed no significant correlation with academic achievement. Moreover, the mean of critical thinking disposition and its components in preclinical and clinical stages revealed not significant correlation and merely curiosity component showed a significant correlation (P=0.04).
