The transition from high school to tertiary education is reported to be a challenging journey for learners. In the South African context, teachers who are appointed to teach Life Orientation (LO) as a fundamental and compulsory subject are closest to the task of supporting learners in the move towards accessing tertiary education. Therefore, this study aimed to examine the support strategies LO teachers use to enhance high school to tertiary education transition. A qualitative phenomenological research methodology was used. The study was conducted in four high schools around the Ngaka-Modiri Molema district in the North West province of South Africa. Four LO teachers were purposively selected to generate data through semi-structured interviews. Data were analysed using thematic data analysis. The findings indicate that support strategies utilised by LO teachers are predominantly informational, and include assisting prospective students with online applications, providing information about career options, funding and pass requirements, providing guidance and motivation, and coordinating career guidance and career information-sharing activities. This study recommends that LO teachers engage in refresher training and proactive engagements with tertiary institutions aimed at supporting prospective learners with up-to-date information to enhance their transition from high school to tertiary institutions, as well as assist LO teachers with information and knowledge to provide holistic support to learners.
