A survey method was used to collect 723 survey questionnaires from undergraduate students at comprehensive-oriented universities owned by the Malaysian federal government. The results of the SmartPLS path model analysis confirm that mentees’ judgments about their capabilities to succeed have mediated the effect of mentees’ intangible and tangible support on mentees’ career development. The novelty of this study establishes the context of highlighting the key elements of mentors’ support that impact mentees’ judgments about their capabilities to succeed, thereby improving mentees’ career development in the universities.
