Our Governance

Visit Danes Educational Trust

De Havilland Primary School is part of Danes Educational Trust. The Danes Educational Trust Board has responsibility for the operation of the Trust, but delegates some of the responsibilities to a local level. Therefore, schools within the Trust have a School Board, comprising local Governors. The School Board holds 4 meetings per year. In addition, each School Board has an Admissions Committee and a Senior Staff Pay and Remuneration Committee. De Havilland Primary School shares its School Board with Jupiter Primary School.

Further information about the Danes Educational Trust governance structure is available on the Trust website
