Our Team

OGAT academies are supported by a central executive team which works with Principals, academy leaders and academy councils to implement the OGAT model and deliver the vision of Students First: Raising standards and transforming lives.

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.

Sir Michael Wilkins, Founding Chief Executive


In January 2001 Sir Michael Wilkins became Head Teacher of Outwood Grange School. Under his leadership, the school has been transformed by his vision to always put “Students First” and Outwood Grange is now one of the highest performing academies in the country, achieving Ofsted Outstanding all grade 1s in 2006 and again in 2012.

Sir Michael was appointed one of the first NLEs in 2006. Outwood Grange Academies Trust currently comprises 13 secondary schools and three primary schools, as well as the Outwood Institute of Education which delivers CPD to schools within the Trust and beyond. The Trust stretches from North Nottinghamshire, through Yorkshire to North Lincolnshire and Teesside.

In 2010 Sir Michael was presented with the award for “Outstanding System Leadership” by Michael Gove, then Secretary of State for Education. He had the honour of knighthood bestowed upon him for his services to education in the New Year’s Honours List 2014 and the citation for this honour read “Sir Michael was one of the first headteachers to be appointed a National Leader of Education in recognition of the national impact he has made supporting schools across the country since 2006. He was the driving force at Outwood Grange Family of Schools in the north of England, which he led to academy status. As an academy sponsor, he has pioneered a hugely successful and high impact model of intervention, transforming schools in special measures at pace.”
