DfE have published an extremely interesting research report on the above which addresses the following questions:
# what are the experiences of schools or academies that have joined a MAT in the last couple of years?
# why have maintained schools decided not to convert to join a MAT?
# why have standalone academies not joined or formed a MAT?
and presents the difference between the experience of being within a MAT and perceptions of what being in a MAT would be like.
If you would like to discuss how to your school might optimally evaluate joining a Multi-academy Trust (or indeed, just have a basic and more general chat about what I do) please contact me at email@example.com or on 017514 499238 for a preliminary discussion.
