Peter J. Derby-Crook MBE
Principal
MEd - Education. University of New South Wales, Australia, BEd (Hons) - Education. Manchester University UK, BEd & Teaching CertEd Education St Mary's University, London UK
Peter has been a teacher for 50yrs and a school Head or Principal for 40 of those years in the UK, the Middle East, China and Asia. His vast experience of what works and what doesn’t in schools, informs and guides his nurturing and collaborative approach to leadership. Peter regards everyone in a school community as equally important in the ever-present drive to do better and raise standards. He believes that schools are about learning and growing… and that applies to everyone, not just students. Known to the community as ‘Mr Peter’, he is accessible and visible as he becomes an active member of the community, commanding a trust and respect relevant to his role. He believes that schools should be a part of life not apart from it and as such endeavours to bring life into the school and the school into real life.
He sees his job as developing the school community such that everyone wakes up in the morning and thinks ‘Great! Another school day!’. Fun should be an aspect of school life, alongside challenge, opportunity and support. Kindness is his favourite human quality and he believes that this is far more effective and influential than operating on fear. His mantra is ‘This is a dynamic learning community, where everyone is nurtured, supported and inspired to be the best they can be. We aim to produce ‘good people’. In 2018, Peter was awareded an MBE by Her Majesty Queen Elizabeth for his services in education to British communities abroad.
