CEIST aims, in a spirit of collaboration, to continually invite its members to reach their potential, in the context of a school faith community which seeks to consciously embody a true expression of Reign of God as announced by Jesus Christ.
CEIST has been formed as an expression of collaborative trusteeship. It has
responsibility for the more than 100 secondary schools associated with the five
collaborating Congregations in the Republic of Ireland. It was founded in 2007.
