The academy can be traced back to 6 December 1675 when the original
grammar school was created by Will of Thomas Gillett. The
Ofsted inspection in March 2007 gave the school an overall grade of "Outstanding". Huish Episcopi converted to
academy status in September 2010. In September 2012, the school was inspected by Ofsted and its rating was downgraded to good. In January 2023, its Ofsted rating was downgraded to inadequate in all areas. A new temporary headteacher was appointed. In June 2023 the school joined the
United Learning group of schools. ==Notable alumni==
