In this working paper, the authors analyse the evidence on schooling outcomes from 75 studies of a range of school interventions. The paper shows that education interventions are not only getting more children into school and keeping them there but are also helping children to learn more. There is compelling evidence of the effectiveness of conditional cash transfers on school enrolment and attendance. Health interventions also had a significant, positive impact on school attendance. While the provision of new teaching materials had no impact on school attendance or language test scores, computer-assisted learning tools had significant, positive impacts on maths test scores. And providing better school buildings significantly improved maths, reading and writing test scores.
