In this episode Femi and Matt are again joined by guest Simon King as they explore the claim that the very best A-level teachers are also, in fact, the teachers achieving the best outcomes with bottom set Year 9, or middle-ability Year 7 students, for example.  Simon provides valuable insight into the differences and similarities between sixth-form teaching and the teaching of younger and less able students, and the trio try to articulate why the elements of teaching that make lessons go well lower down the school (expectations, explanations, differentiation, relationships and routines, for example) only serve to strengthen teaching as students move into Years 12 and 13.
