This article reports on a study that tested theory predicting differences in personality endowments between first-year and second-year accounting students, as well as the potential influence of personality on academic performance in the context of a large South African university. Data from 1 380 first-year and second-year accounting students was used to test theory predicting gendered differences in the relationships between personality and both throughput and performance. Multiple linear regression and multivariate analysis of variance (MANOVA) estimations were applied. The findings suggested that fewer students with openness and agreeableness continue to second-year accounting studies. While conscientiousness might not be a primary differentiator of performance at first year, at second year it dominates as a predictor of performance. The findings are expected to generalise to other contexts to the extent that such contexts share characteristics with the context under study.
