Ashburton College

Ashburton College is naturally zoned by the school's relative isolation (the nearest alternative state secondary school is Mount Hutt College, 35 km away in Methven), therefore does not need to operate an enrolment scheme. The school has an effective service area of the entire township of Ashburton and much of the coastal half of Mid-Canterbury, with Mount Hutt College in Methven, Ellesmere College in Leeston, Geraldine High School in Geraldine, and the Pacific Ocean bounding the Ashburton College service area to the west, north, south and east respectively.^[4]

At the April 2013 Education Review Office (ERO) review of the school, the school had 1173 students enrolled, including twelve international students. Fifty-one percent of students were male and 49 percent were female. Seventy-seven percent of students identified as New Zealand European (Pākehā), ten percent as Māori, four percent as Pasifika, three percent as Asian, and six percent as another ethnicity.^[5]

As of July 2025, Ashburton High School has roll of 1345 students, of which 208 (15.5%) identify as Māori.^[1]

As of 2025, the school has an Equity Index of 467,^[6] placing it amongst schools whose students have average socioeconomic barriers to achievement (roughly equivalent to deciles 5 and 6 under the former socio-economic decile system).^[7]

In 2012 Ashburton College was first equal in The Clean Green Business Award, won the Large Business Award and was also named the Overall Supreme Award winner in the Ashburton Business Association biennial business awards.^{[citation needed]}
