Governance & Funding

Governance is a key element of the leadership and management of the Trust itself and of the schools individually and collectively. Please click here to see our Governance Structure.


The Trust (itself accountable to DfE) is the body to whom schools are directly accountable. It delegates autonomy to each Local Governing Board/Body (LGB) or School Improvement Board (SIB) according to the Scheme of Delegation. 


The Trust Board is made up of experts in UK and international education as well as private sector professionals with a wide range of commercial experience and expertise. In keeping with our vision we also place an emphasis on attracting Trustees who have backgrounds and networks in Sport and the Arts. The Board acts as guardian to the Trust vision, and ensures that progress towards its fulfilment is underpinned with the highest standards of compliance with our regulators so that public funding is very well-used.


Serving as a governor in a GST school requires a commitment to the seven principles of public life and to a code of conduct which puts the school and its pupils at the centre. GST governors meet formally every thirteen weeks (i.e. once every school term) and much of the real work is done between these meetings, through Working Groups and individual contributions to the school’s life according to each governor’s skills and the needs of the school.


The role is very different from that of a governor in a Local Authority school, recognising that the Head is the school’s Chief Executive and the Board is there to advise, support and challenge through appropriate channels and to evidence the impact that governance is having on the school’s progress. As in the world of non-executive directors, GST governors are expected to bring their skills to bear and to work in co-operation and collaboration with the staff team, the whole Local Governing Body and the Trust to bring about rapid and sustained improvement for the pupils they serve.


The Trust is responsible for the appointment, performance management and professional development of the Heads, though the LGB’s work has a vital role to play in highlighting and evidencing the impact that the Head and governors are making through their termly meetings. Through their work in and for the school, governors come to know the school community and to be well-informed about its performance, able to talk about it confidently and accurately to the Trust, to Ofsted, to parents and to interested local groups.


We very much appreciate the work that governors do and the part they play in the success of the schools they serve and indeed of the Trust. We hope that governors find reward in the impact they make on young lives and their individual experience of the living reality of the GST motto: Proud Traditions Wide Horizons High Achievement.
