The National Middle Schools' Forum (NMSF) is a national education association dedicated exclusively to the promotion and support of middle schools in England.

The initial organisation was in part due to the recent Audit Commission response which proposed a rationalisation of primary education to remove middle schools.

It is the current aim of the forum to provide a focal point for networking and discussion among the remaining Middle Schools in England.

It is recognised as a partner in work with government agencies, including the Department for Children, Schools and Families and the Qualifications and Curriculum Authority.

The forum holds a national conference for members, as well as sending delegates to international events, including the European League for Middle Level Education.
