The study focused on the predictive abilities of personality traits and self-efficacy on academic dishonesty among students. After satisfying ethical protocols, the study surveyed 453 higher education students using an analytical cross-section design. Respondents were exposed to respond to three constructs such as personality traits scale, academic self-efficacy scale, and academic dishonesty scale. The data were quantitatively analyzed using means and standard deviations, frequencies and percentages, and regression. The study revealed that conscientiousness was the dominant personality trait. In addition, the study revealed that dishonest academic behaviours were exhibited among students despite their high level of self-efficacy. Furthermore, conscientiousness, openness and self-efficacy significantly predicted academically dishonest behaviours of students. Therefore, it is recommended that students be presented with opportunities to maintain their high level of self-efficacy to help reduce incidents of academic dishonesty. The study's findings appear original as they may serve as panacea for curbing dishonesty in teacher education programs in Ghana to churn credible teachers that might mount the teaching podium to impart knowledge onto the young that serve nations in the future.
