 In 1977 the administration of the school was taken over by the Roman Catholic Diocese of Lancaster although Sister Maureen remained as Head Teacher until 1984 and sisters of the order still teach there.Initially the reunited school operated on two campuses, but the St Joseph's campus was shut down in the early 1980s and sold for housing development.Further expansion occurred in 1982 when the school was merged with two Catholic former secondary modern schools, St Thomas of Canterbury's and St Catherine's, which themselves had merged to form All Saints RC High School.
