Bio: I'm a Partner at the Innovation Unit. I've been a secondary school teacher and headteacher most of my career. Subsequently was a director at the National College for School Leadership, where we ran the Networked Learning Communities programme, partnered by IU. I have worked on transformation programmes in America, Australia and South Africa as well as the UK. In times when external control and accountability feel to be constraining and regressive forces, I am passionate about the possibilities to do astonishing work. Schooling and learning need reimagining. We know enough to be able to do it!
