Counthill School formerly a high-achieving Grammar School, was a mixed gender secondary school for 11- to 16-year-olds in the Moorside area of Oldham in Greater Manchester, England. The school had approximately 900 pupils on roll and its motto was Animo Atque Fide. Although sometimes mistakenly thought to be the highest secondary school above sea level in the country, the site sits between 280 and 285 metres, which is lower than others such as Buxton Community School at 320 metres.
