First of all, we wanted small schools -- about 300, 400 pupils -- 14 to 19 year-olds, and critically, about 80 percent of the curriculum done not through sitting in classrooms, but through real-life, practical projects, working on commission to businesses, NGO's and others. That every pupil would have a coach, as well as teachers, who would have timetables much more like a work environment in a business. And all of this will be done within the public system, funded by public money, but independently run. And all at no extra cost, no selection, and allowing the pupils the route into university, even if many of them would want to become entrepreneurs and have manual jobs as well. Underlying it was some very simple ideas that large numbers of teenagers learn best by doing things, they learn best in teams and they learn best by doing things for real -- all the opposite of what mainstream schooling actually does.
