Educated at Steyning Grammar School, West Sussex, Mrs Kerr-Dineen went on to gain an MA in English at Trinity College, Cambridge and to pursue graduate study at Christ Church, Oxford. Early in her career she taught for the Open University in the South West and Oxford.

Her teaching career spans over twenty years, including thirteen at St Edward’s Oxford where she was also a boarding housemistress and ultimately Director of Studies before moving to be Warden of Forest School, London. She is married with four children aged between 20 and 27.

Mrs Kerr-Dineen places great emphasis on teaching – she teaches all the Third Form in the course of the year – and on the centrality of the individual pupil to everything a school does. Above all, she sees the work of a school is to guide and inspire children not only in the classroom, but in all aspects of their development as young adults.
