Academies are schools funded by the government with the freedom to govern independently – but all are accountable to the Secretary of State for Education. To share resources and best practice, many are part of multi-academy trusts – a network of schools under one legal body. 

Ark John Archer Academy is part of Ark Schools - a leading education charity and one of the country’s top-performing academy operators. Ark is non-denominational and does not make any profit from running its schools. 

Ark’s relationship with the Secretary of State is set out in the master funding agreement. There are also supplemental funding agreements for each individual school in the network, including Ark John Archer Academy. 

Every school in the Ark network is the legal responsibility of the Ark Schools Board. This board focuses on statutory duties and delegates most day-to-day responsibilities to each school’s individual Local Governing Body (LGB). This means that Ark John Archer Academy's governors are able to concentrate on the things that really matter – educational strategy, school outcomes and aspiration.

The current Clerk to Governors is Katie Bird ( Governors can be contacted through the Clerk.
