Learning remains largely out of reach for many of the most vulnerable children around the world. In low- and middle-income countries, an estimated 56% of children cannot read a simple text by the age of 10. This share is projected to rise to 70% after the pandemic. The school closures imposed by the COVID-19 outbreak, coupled with an enduring tendency in low-income countries to allocate a limited share of the national education budget to the most vulnerable, are further widening inequalities in the global learning crisis landscape. The Let Us Learn (LUL) initiative implements innovative education programmes to improve learning for the most vulnerable children in five countries with high levels of out-of-school children: Afghanistan, Bangladesh, Liberia, Madagascar and Nepal. This report documents the outcomes, lessons learned and recommendations based on the experience of the initiative across four types of learning programmes spanning the education lifecycle: (1) pre-primary education; (2) accelerated learning pathways; (3) programmes to reduce barriers to access and stay in formal school; and (4) vocational training.
