This study explored and described the experiences regarding clinical supervision of master's students in professional psychology programmes in South Africa. Four participants were purposively selected from four different universities. The participants engaged in reflective writings and in-depth interviews over a one-year span. Data were analysed through interpretative phenomenological analysis (IPA). Findings indicated that supervision, as compulsory pedagogical activity for these students, serves an essential purpose, as it was identified as the main contributor towards their professional developmental journeys. Interpretation of the findings yielded themes of significance across cases. Identified themes are emotional support, self-acceptance, autonomy and personal growth. Themes were contextualise within broader educational theories as well as within professional career developmental theory in psychology. While becoming a psychologist is known to be a difficult journey, the results indicated that it can also be rewarding, and holds the potential to enhance growth which can be unlocked by the supervisory relationship.
