Effective governance within MTOAT is achieved through a shared vision and a connected thread of delegated responsibility and accountability. Whilst the Board cannot ever delegate its accountability, it can and must delegate some of the detailed scrutiny, oversight and decision-making.

MTOAT’s governance structure is:

The Members are the guardians of the constitution (the Articles of Association) and the application of MTOAT vision and goals within the Trust.

The Trust Board  is accountable to the Members, to the Secretary of State for Education and to the wider community for the quality of the education provided to all of our registered students and for the appropriate expenditure of public money.

The Local Governing Board for each school or college – provides scrutiny of the delivery on the academy improvement plan and academy budget, holding the school’s leadership to account. The Chair (or Vice Chair when appropriate) of each Local Governing Body is a Director/Trustee of MTOAT and joins the MTOAT Trust Board. The Chief Executive Officer and Chair of the Trust Board have the right to attend Local Governing Board meetings of any Local Governing Body.
