Our Team

OGAT academies are supported by a central executive team which works with Principals, academy leaders and governors to implement the OGAT model and deliver the vision that:

“The whole point of schools is that children come first and everything we do must reflect this single goal”. Sir Michael Wilkins, Founding Chief Executive.

Our board of trustees oversees the central organisation and is the legal governing body for all OGAT academies. The board of trustees delegates many of its functions to the Academy Council in each academy. The local community, parents and staff are represented on each Academy Council.
