SofH, the Society of Heads (previously SHMIS) is an association for over 100 Heads – mostly of smaller independent senior schools, with a tradition of boarding. It was established in 1961 to provide a forum for the exchange of ideas, because membership of the HMC was full. Some Headmasters are members of both HMC and the Society of Heads.

Its aim is to promote independent education, represent its heads and schools at local and national level, foster partnerships with a variety of other organisations (including the state school sector, government, business and the wider community), to maintain standards and provide support for its member heads.
