Over recent decades, much has been achieved in developing Catholic school religious programmes, chaplaincy and community life but the ordinary curriculum now needs to be the focus of the school's Catholic ethos. The International Baccalaureate shows the structure by which an educational vision can explicitly inform a school's core curriculum. Using the IB structure, but with different content, Catholic schools can place the call of Christ at the heart of every subject area. In an appendix, a Catholic school leader describes how her school has set about implementing this vision in practice.
