Assistant Head - Teaching and Learning
Mr Dan Glover

BSc (Loughborough)

Mr Glover was educated at Great Torrington School and North Devon College, before studying Geography at Loughborough University. He went on to undertake his PGCE at Nottingham University and his first teaching post was at Longsands Academy, St Neots, Cambridgeshire for three years. During this time he became the Head of a Key Stage Three House. A two years overseas position of Head of Geography at Greentsteds International School, Kenya allowed him the opportunity to broaden both his teaching and travelling experiences.

He returned to Longsands Academy as the Head of Key Stage 4 where he had the overall responsibility for raising standards and for the pastoral support of the entire Key Stage 4 cohort. In 2016 he made the move with his family to Somerset when he was appointed the Head of Geography at Sexey’s School, a role that he thoroughly enjoyed.

The experiences that he have gained in Cambridgeshire, Kenya and Sexey’s allowed him the opportunity to undertake the current role of Assistant Headteacher, Teaching and Learning. He is passionate about teaching and learning and is building upon the outstanding practice that is taking place in Sexey’s with a forward-thinking and student-centred outlook in all that we do.
