Peer-to-Peer Mentorship Programmes have gained attention as a promising strategy for addressing youth unemployment in South Africa's informal settlements. The analysis draws on qualitative data from three years of evaluations within South African informal settlements, focusing on the impact of mentorship programmes on youth engagement and skill development. The theoretical framework presented offers a robust model for policymakers and practitioners to design and scale effective Mentorship Programmes that can address youth unemployment effectively in South African informal settlements. Based on the findings, it is recommended that governments and NGOs invest in comprehensive training programmes for mentors, provide ongoing support to mentees, and conduct regular evaluations to ensure continuous improvement of mentorship initiatives.
