Despite there being significant numbers of state maintained Catholic schools in England, they have until recently proved to be of interest only to a minority of researchers, usually those directly involved in their promotion. New Government initiatives encouraging further diversity in the provision of schools have proved controversial and, in reopening the religious debates of the 19th and early 20th centuries, have prompted interest in the academic performance of Church schools. This paper takes a longitudinal approach in reviewing information already in the public domain, as well as presenting new evidence based on national examination performance data. Standards of academic attainment at Key Stage 4 in Catholic schools compare favourably with national norms. Such schools are particularly effective with more socially disadvantaged pupils and, as such, appear to offer much to the common good of society. Further areas for research are suggested.
