The paper reported study findings from a cluster randomized controlled trial testing whether providing school fees, uniforms, and school supplies could help keep orphan adolescent girls in school and prevent HIV risk behaviors. After two years, the intervention significantly reduced school dropout by 82% and early marriage by 63%. Compared with control participants, the intervention group also reported greater school bonding, better future expectations, more equitable gender equity attitudes, and more concerns about the consequences of sex. Study participants lived in rural areas and were, on average, 13-14 years old at follow-up. A cost effectiveness analysis (CEA), led by PIRE Co-Investigator Ted Miller, found that support for day school, but not for boarding school, was cost effective; boarding school was much more expensive and did not improve benefits.
