Ashburton College is a state coeducational secondary school located in Ashburton, New Zealand. It opened in 1965 following the merger of two Ashburton secondary schools: Ashburton High School and Hakatere College, and moved to its current site in 1974.^[3] Serving years 9 to 13, Ashburton College has a roll of 1,293 students as of February 2024.^[1]

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]

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]}

In 2008, The Education Review Office ranked the school the top in the country for the promotion of male's learning.^[6]

Statistics from the 2008 NCEA results ranked the school fifth in performance out of the 19 decile seven to nine schools.^[7]
