Dr Jo Phillips has taught in four different sixth form colleges, then moved into higher education, and has been teaching in universities for the last 15 years. This puts her in a rare position - she's taught not only A-level students but hundreds of undergraduates too. She currently teaches Landscape Architecture at the University of Sheffield. Martin Griffin has 20 years' experience teaching post-16 students, and has been a head of faculty, assistant head teacher and deputy head teacher. He was the director of sixth form at The Blue Coat School and now works with schools and colleges to design and implement character development and mindset programmes.
