This article examines the experiences and perceptions of academics about student engagement and how their professional practice in a professional community enhances students’ persistence and success in a university in South Africa. While previous research has widely focused on students’ perception of how student engagement enhances student success and persistence, there is a paucity of research on the position of academics who constitute a professional community on how they could enhance student engagement in higher education. To address this knowledge gap, a qualitative research approach was used to gather and analyse data from a sample of 26 academics who shared their perceptions and experiences about how they contribute to enhancing student engagement in the university. Consequently, four main themes were explored to provide conceptual and empirical structure to the notion of engagement among academics in an expert community: institutional structure and culture, affective, behavioural and cognitive engagement. The results revealed that the cognitive, behavioural and affective features of student engagement as well as institutional structure and culture explain how academics experience and perceive how their professional practices enhances student persistence and success in relation to engagement. Particularly, the study shows that institutional culture, expert culture, professional community and institutional structure influence the perceptions and experiences of academics about student engagement. Conversely, when academics do not follow the expert and academic cultures of the institution, it could lead to poor professional practices that are antithetical to student persistence and success.
