The independent/ state school partnerships (ISSP) programme was set up in 1998 by the Department for Education and Skills (DfES), in conjunction with the Sutton Trust, with the aim of providing structure and funding for the co-operation between the private and public sectors in education.

In practice this has meant that Carleton High together with The Kings High School, Wakefield Girls High School and Queen Elizabeth Grammar School have worked together to deliver a series of sessions on Maths and Science topics such as the Junior Maths Challenge, Building a Rocket Car, Galileo & Newton, Maths into Music etc.
