Nearly the whole of America's partisan politics centers on a single question: Can markets solve our social problems? And for years this question has played out ferociously in the debates about how we should educate our children. Policy makers have increasingly turned to market-based models to help improve our schools, believing that private institutions - because they are competitively driven - are better than public ones. With The Public School Advantage, Christopher A. and Sarah Theule Lubienski offer powerful evidence to undercut this belief, showing that public schools in fact outperform private ones. Decades of research have shown that students at private schools score, on average, at higher levels than students do at public schools. Drawing on two large-scale, nationally representative databases, the Lubienskis show, however, that this difference is more than explained by demographics-private school students largely come from more privileged backgrounds, offering greater educational support. After correcting for demographics, the authors go on to show that gains in student achievement at public schools are at least as great and often greater than those at private ones, and the very mechanism that market-based reformers champion-autonomy - may be the crucial factor that prevents private schools from performing better. Alternatively, those practices that these reformers castigate, such as teacher certification and professional reforms of curriculum and instruction, turn out to have a significant effect on school improvement. Offering facts, not ideologies, The Public School Advantage reveals that education is better off when provided for the public by the public.
