St. Mary’s Catholic Secondary School was founded by the Catholic Church to provide education for children of Catholic families. Whenever there are more applications than places available, priority will be given to Catholic children in accordance with the oversubscription criteria outlined in the document below. The school is conducted by its governing body as part of the Catholic Church in accordance with its trust deed and articles of association, and seeks at all times to be a witness to Our Lord Jesus Christ.

Both internal and external pupils wishing to enter the sixth form will be expected to have met the same minimum academic entry requirements for the sixth form. These are detailed in the Sixth Form Prospectus.
