The Le Chéile Schools Trust

This Trust comprises the schools of fourteen religious congregations. The aim of the Trust is to carry on the legal, financial and inspirational role of trusteeship that has, up to now, been done by individual congregations. It carries out the legal and inspirational role of trusteeship. This is a significant development in Irish education as the Catholic Church and the individual religious congregations renew and reformulate their commitment to Irish education.
