Since April 2008, TreeHouse School has been a Non Maintained Special School. This is a type of special school run by a charity rather than a local authority, which can receive certain types of Government funding. The Governing Body is separate from, but over-lapping with, the Board of Trustees in that two Governors are also Trustees and the Trustees receive reports from the Governing Body.  By law we do everything that a Governing Body does in a local authority school except manage the budget and the premises.

The full Governing Body meets six times in the year as do its two sub committees: Curriculum, Assessment and Pupil Progress Committee and the Pupil Welfare Committee but Governors are also actively involved in many aspects of school life. They are completely committed to the success of the school and to ensuring the best possible provision for our pupils.
