Upper schools are a type of secondary school found in a minority of English local education authorities. Whilst most areas in England use a two-tier educational system – primary (ages 5–11) and secondary (ages 11–16 or 11–18 if they operate a sixth form) – counties such as Leicestershire, and Suffolk use a three-tier system of lower (ages 5–9 or 10), middle (ages 9 to 13 or 14), and Upper schools (ages 13 or 14 to 16, or 18 if they include Years 12 and 13, known as a Sixth form).
