Raising the floor on learning levels: equitable improvement starts with the tail

In this note, the authors examine the equity and inequality dimensions of the learning crisis. They explore several questions, as follows: 1. How should we understand equity and inequality in global education? 2. Where does inequality in learning outcomes come from? 3. Do countries improve their averages by reducing non-performance or improving high-performance? 4. Is there more inequality between or within countries? 5. What are the possible policy implications?
