How can a teacher make sure, in the brief time that an inspector (or other assessor) spends in their classroom, that the lesson ticks enough boxes to impress -- AND gain that outstanding grade? The Perfect (Ofsted) Lesson is a great new book by Jackie Beere designed to help improve school's Ofsted Results. Jackie Beere leads the teacher through the criteria to search for the 'x-factor' - the magic ingredients that will elevate lessons to outstanding. The 'x-factor' means demonstrating exceptional progress in learning and that the quality of learning is exceptional.
