The international engineering education community has reached a consensus regarding the need to enhance engineering students' awareness of and capability to provide sustainable services in their future careers. Based on a modified college impact model, this study analyzed the impacts of curricular emphasis, curricular instruction, and sustainability-related career self-efficacy on the sustainability-related career expectations of engineering students and investigated the moderating effects of gender on the relationships among the research variables. The results show that both curricular emphasis and curricular instruction have direct positive effects on the sustainability-related career expectations of engineering students; sustainability-related career self-efficacy plays a partial mediating role in this process; and gender significantly moderates the influence of curricular emphasis and curricular instruction on sustainability-related career expectations. The findings of this study provide empirical evidence that can be used by higher education institutions and engineering educators to enhance the belief of engineering students in their ability to solve sustainability-related issues in their future careers and promote the diversification of engineering education.
