St. Thomas’ High School, Jhelum, Pakistan was founded by Sr. Maureen Costelloe of the Presentation Sisters under the Roman Catholic Archdiocese of Lahore. It started as a boys school but is now co-educational with a girls’ Section and a boys’ Section. It provides education up to Matriculation standard. The Principal is Sr. Riffat. The Presentation Convent School, Jhelum was set up in 1950. Sr. Maureen saw the need for a Senior School for Christian boys as the boys from Presentation Primary School had nowhere to go when they finished Class 5. For this purpose St. Thomas’ High School was built.
