This is the concluding chapter of the book Privatization in and of Education. It summarizes the key messages from the chapters and synthesises the messages to the predictive future of education policies in the dimensions of private–public. We rely on the argument that private schools are more efficient than public schools after controlling for the differences in inputs, including students. So theoretically there is something beyond resources that makes private schools more efficient, what we intend to discuss. Moreover, the biggest contemporary problem of private schooling is related to the poorly mitigated trade-off between efficiency and equity or inclusion, and this applies to various contexts and cases in this book. Thus our policy perspective is to reveal interventions needed for both private and public schools to flourish and increase horizontal diversity without between-school vertical segregation.
