Child mortality remains a significant public health concern in Benin, with interventions aimed at reducing these rates. A mixed-methods approach combining qualitative interviews with quantitative data analysis was employed to assess changes in child mortality rates before and after the intervention. The findings indicate a 15% decrease in child mortality rates among children aged under five years old post-training, attributed to enhanced health awareness and basic healthcare knowledge dissemination. School-hosted training of community health workers has shown promise in reducing child mortality, suggesting its potential as an effective public health strategy in Benin. Further implementation should focus on scaling up the programme across more schools and communities to ensure broader impact.
