The purpose of this study was to investigate the role of self-efficacy enhancement in building pre-service teacher resilience to prevent symptoms of burn-out in Swaziland; how engaging in reflective practices can act as a protective factor. Not much research focuses on pre-service teacher burn-out and how to mitigate its effects, and this creates a gap that this study sought to address. Through the interpretivist perspective, and employing participatory action research (PAR) and some elements of pre-test, post test design, seven pre-service teachers who were doing their final year of a three year teacher’s diploma programme; four males and three females were engaged in the study. Data were collected by using the resilience scale questionnaire, participants’ reflective journals, researcher’s diary and transcribed recordings from a focus group interview. Three themes emerged; (1) that pre-service teachers in Swaziland do experience symptoms of burn-out during teaching practice. Seven risk factors that contribute to the experience of burn-out were cited by participants; learners’ behavioural issues, heavy workloads, demanding supervisors, lack of support from colleagues, teaching learners who are high achievers, feelings of inadequacy and lack of prioritising. (2) Pre-service teachers were able to draw strength and possibly avert burn-out by mobilising external and internal protective sources. (3) Reflective practices proved to be a viable intervention that enhanced pre-service teachers’ self-efficacy and helped promote resilient coping. Future research might look into other factors that predispose pre-service teachers to stress and how reflective practices may be infused in the curriculum for pre-service education.
