The school in Mornington Road, Woodford Green, scored maximum possible marks in 22 out of 25 categories with an inspection team who spent two days in the school at the start of this month. In their report, inspectors wrote: "There is a clear vision and a hunger for improvement, building on the school's record of outstanding success. The outstanding and consistent leadership of the headmaster over a quarter of a century is complemented by the exceptional management of senior and middle leaders." The report noted that a high proportion of students gained the highest grades at GCSE and that progress made by students who joined the sixth form with lower grades was particularly good. Headteacher Paul Doherty wrote: "My warmest congratulations to all for a marvellous and truly outstanding outcome."
