Abstract
This article is the first part of a debate with David Hargreaves about the ideas expressed in his article ‘Diversity and choice in school education: a modified libertarian approach’. It discusses the difficulties of using cost‐benefit analysis in education, examines in detail some of the documents on which Hargreaves's argument is based and traces the development of policy on school choice. It is argued that policy on choice must be understood within a consideration of the wider social and political context in which that policy has arisen. The article then documents the various new forms of selection that have accompanied increased choice and considers problems of social segregation. The article concludes with suggestions on how the system might be reformed.
