The 'Let Us Learn' initiative aims to improve educational access for the most vulnerable children in five countries (Afghanistan, Bangladesh, Liberia, Madagascar, and Nepal) who are often out of school. By employing innovative measures and mixed methods research, the project seeks to identify effective strategies for supporting learning from early childhood through vocational training. The initiative focuses on boosting retention, access, and overall educational outcomes in severely marginalized communities, partnering with UNICEF for evidence-based decision-making.
