Peer-led health promotion strategies in schools have been found to be effective in promoting healthy behaviours amongst youth. This study aimed to evaluate the views of the peer educators in implementing a health education programme using a qualitative approach. Informal discussions and eight in-depth interviews were used to explore the views of the 10 peer educators. Information from the interviews was transcribed verbatim, analysed, and coded thematically. The themes that emerged from the analysis of the informal discussion and in-depth interviews were grouped into categories, which included peer educators' experience of implementing the intervention, personal growth and experience with interacting with young people, and personal reflection on the presentation of the intervention. The role of peer educators was shown to be crucial to the success of peer-led programmes, but it is clear that equipping and supporting them through the process of implementation is essential.
