This article examines the notion of spiritual development as it was conceptualised for state schools in Britain through the Conservative Government's education reforms of the 1980s and 1990s, reforms which also introduced the National Curriculum. The article puts forward the argument that spiritual development was conceptualised in such a way as to attempt to reinstate progressive pedagogical values rejected by the National Curriculum reforms, but that the conceptualisation led to two conservative outcomes. First, spiritual development was not sufficiently robust to counteract the reforms and may have helped ease their passage. Second, education for the development of spiritual beliefs and values continued to be primarily located in Religious Education, even though a first principle of spiritual development was that spirituality should not be synonymous with religion in order that spiritual development should be inclusive. The article recommends that changes to Religious Education should be encouraged to ensure schools can provide opportunities for an inclusive and progressive education for spiritual development.
