Purpose: This research examines whether mentoring is a predictor of entrepreneurial intentions. It also explores how intent translates into action through implementation intentions. The study tests if the mentoring-intentions association is mediated by self-efficacy. The potential moderating effect of achievement motivation on the relationship was also investigated. Design/methodology/approach: PLS-SEM was used to test the hypotheses of the 242 valid responses collected from final-year students from Libyan public universities. Findings: Results show that self-efficacy partially mediated the mentoring-intentions association, while motivation negatively moderated the relationship. Entrepreneurial intentions had a significantly strong effect on implementation intentions. Research limitations/implications: The results verify mentoring as a practical socializing instructional approach. Therefore, universities should implement structured mentoring programs, offering emotional guidance, counsel and networking opportunities. Also, mentors should undergo training, and progress tracking is essential for improvement. Originality/value: Examining entrepreneurial self-efficacy as a mediator and achievement motivation as a moderator in the mentoring-intentions association is unprecedented. The findings narrow the search for antecedents to entrepreneurial intentions and pinpoint intervention points.
