Adrian Ball – Chief Executive Officer

Since qualifying as a PE teacher in 2003, Adrian has always worked in schools located in areas of high socio-economic deprivation. Through a variety of different roles, as Vice Principal, Principal, and Executive Principal he has been part of a number of turnaround successes – most notably as Principal of Thetford Academy, where he led the school out of special measures to its first Good rating, with leadership recognised as Outstanding, in just 15 months.

In December 2014 Adrian took on a wider Executive Principal mentoring role of the new Principal at East Point Academy and supported in the removal of the academy from special measures in March 2015, with a good judgement for leadership.

Most recently Adrian was the Chief Operating Officer for the Inspiration Trust; a Multi-Academy Trust of 14 schools across Norfolk and North Suffolk, where he was responsible for the delivery of an effective operating model to ensure the educational objectives of the Trust are achieved. 

Adrian is also a member of the Norwich Opportunity Area Partnership Board, chairing the Teaching & Attainment committee, which is part of a national Department for Education strategy to improve social mobility through education in the areas of most need, and has spoken on this subject, amongst others, to colleagues within the education sector. 

He has also competed for Great Britain in duathlon, coming 5th in the 2014 European Championships, and 16th in the 2014 World Championships.

Jacqueline McCamphill - Director of Trust Development

Jacqueline joined DEMAT in November 2016 as a part time consultant and became the Assistant Director for Innovation and Business Development in April 2017.  She joined the Trust because she was attracted to its ethos, vision, values and high-quality team in their pursuance of improving outcomes for children and young people, which so closely align with her own.

In August 2018 Jacqueline became the Director of Trust Development, where she has accountability for Trust Governance, Conversions, Estates and Business Development opportunities including stakeholder management.  Prior to this, she was appointed by Trustees to be the Chief Executive of the Eastern Leadership Centre (a Cambridge educational charity) to lead the charity closure: she was successful in leading a solvent closedown of the charity from April 2016 to April 2017, working with key Trustees.

This executive role has followed 17 years of senior management experience across the charity, government and private sectors:

  • Senior Manager at the Eastern Leadership Centre, working with national charity partners and local government-related sold service provision, specifically around national school governance
  • Regional Manager for the East Region for the national Training and Development Agency (TDA) on workforce development and ‘every child matters’ initiatives
  • Bursar at Hinchingbrooke Secondary School in Huntingdon.

In August 2018, Alex took on the post of Director of Finance at DEMAT, and saw the HR function join her Directorate.  Alex believes that education offers the greatest opportunity for all children, collectively and individually to unlock their potential, regardless of their start in life. It was in this belief that Alex joined her local school as a Governor in 2015, and so was eager to join DEMAT as she believes they share a common goal of furthering young people’s education through collaboration, support & challenge.

Amy Weaver - Director of Inclusion and Safeguarding

Amy joined DEMAT in October 2017.   Her education experience has ranged from primary through to Key Stage 5, across mainstream & specialist settings in three countries. She has been responsible for the leadership of SEND, achievement of vulnerable groups and Child Protection for nearly 15 years. Alongside her practical experience, Amy gained a Post Graduate Certificate in Education and Masters of Arts in Education (Equality & Diversity).

Whether moving to a secondary school in challenging circumstances, working with primary aged pupils with Social, Emotional or Mental Health needs, or running an outstanding provision designed to enable students with Autistic Spectrum Conditions (who would otherwise be out of education, excluded or in a special school) to access a mainstream setting, one principle has remained her clearest vision for inclusion:

“Sameness is not fairness: Fairness is not giving everyone the same thing. Fairness is giving each person what they need to succeed”

With the challenges faced by teachers and school leaders in today’s education system, this principle becomes ever more difficult to enact, but even more necessary to maintain.  Amy is dedicated to school improvement, and to working with and in schools to ensure all children and young people are safe, secure and supported to achieve their potential.
