The thesis underpinning this study is that Catholic schools in Wales may need fundamentally to re-imagine their vision and praxis in the light of significant changes to the staff and student populations of Catholic schools during the last decades of the twentieth century. The first patt of the study reflects upon some of those changes. Building on an analysis of the expectations of Catholic schools circumscribed in Vatican and national documents, there is an exploration of some of the social,educational and ecclesiological changes -of recent years. A proposal is suggested that Catholic schools in Wales may need to explore and respond to these changes if they are to fulfil the mandatee stablished for them. Tle second part of the study examines the attitudes and experiences of Catholic school students in Wales regarding their schooling. The premise is that the voices of the students are important and that they can inform the reflections that Catholic school educators must undertake if Catholic e ucationin Wales needs renewal. The analysis of student attitudes and experiences of Catholic schools in Wales is built upon a Likert-style questionnaire c mpleted by students of Year 11 in most of the Catholic secondary schools in Wales.
