The global shortage of learning is truly shocking. Today, most children in the world are not reaching even basic levels of literacy and maths as they are either not in school or they’re in a school but not really learning. It’s an uncomfortable fact reinforced by the World Bank’s inaugural report on education. The crisis is worst in sub-Saharan Africa. It is home to more than half the world’s out-of-school children, but it receives only a quarter of global education aid. The latest insight from the most authoritative research points to low quality and quantity of teaching in low and middle income countries, indicative of ineffective systems, as a major root cause.
