"History of Education" has published a steady stream of papers on the history of secondary education over the first 40 years of its existence. This corpus of research has been generated in the context of renewed interest in the history of secondary education that has been stimulated by developments in social and historical inquiry as well as by the contemporary onset of intensive reform of secondary education in many countries. "History of Education" has made a distinguished contribution to this new literature, especially in relation to an understanding of the secondary school curriculum, elite forms of secondary education, and increasingly in relation to secondary education for girls and secondary education policy. Some other key themes and topics have been generally less to the fore and require further detailed investigation. (Contains 76 footnotes.)
