Low-cost private schools are burgeoning across the developing world, where typically they outperform public schools. But quality can be improved further, which is why I’ve helped launch several chains. These have invested in curriculum, assessment and teacher training, and looked for economies of scale. I’m also proud of my work with self-help associations of low-cost private schools. These engage in raising quality of educational provision too, as well as ensuring that governments know the positive contribution low-cost private education is making. Finally, I’m also involved in bringing the low-cost private education model to England too.
