A digital version of the Federal Ministry of Health (FMoH) national curriculum was developed to train 160 Health Extension Workers (HEWs), incorporating supplementary video and quiz content on the OppiaMobile platform. This initiative addressed the challenge many HEWs faced due to limited access to hardcopy curricula, which hindered their ability to review and practice. A follow-up assessment was conducted one year after the training to evaluate the application of the skills learned, focusing on key health areas such as Vaccination/Immunization and Maternal and Child Health.
