Community-based HIV/AIDS prevention programmes have been implemented in schools across Kenya to address high rates of infection among secondary school students. The review encompasses a critical analysis of academic literature, focusing on methodologies used in impact evaluations and reporting trends across various studies. A notable finding was the mixed effectiveness of educational materials with some students showing increased knowledge but unchanged behaviour regarding risk behaviors. While certain aspects of the programmes were effective, there is a need for more tailored approaches to engage students effectively in HIV/AIDS prevention efforts. Programme developers are advised to incorporate interactive and culturally sensitive elements into their curriculum to enhance student engagement and impact.
