Admissions
The school is selective, requiring pupils to pass an eleven plus examination in order to gain admission. In 2013, The Telegraph ranked it third in a list of the most oversubscribed schools in England, describing it as part of "an elite group of grammar schools...with more than a thousand applications". The school sells mock entrance examinations to parents of prospective pupils, which generated an income of £70,000 in 2016. 5 News broadcast a report on the school in 2016, interviewing headmaster G D Ironside and pupils and covering issues including elitism and life at the school. The school admits pupils from ages 11–18, or years 7–13 in the English academic system, although the majority of students join the school in year 7 or year 12. There are 140 pupils in each year in the Lower School (years 7–9) and Upper School (years 10 and 11), and slightly more in the sixth form, varying year-on-year.
