About Colchester Institute
Colchester Institute sits within the Essex local authority as a state-funded, mixed-gender secondary school for students aged 16 to 99, making it unusual in offering post-16 and adult education alongside its core provision. In the local landscape, it ranks 71st out of 86 same-type schools in Essex, placing it firmly in the bottom tier of the county. For context, the top-performing peers in the area include King Edward VI Grammar School, Chelmsford, Colchester Royal Grammar School, and Brentwood Ursuline Convent High School, all of which achieve Progress 8 scores above 1.0. The nearest Outstanding-rated school is Colchester County High School for Girls, just 1.3 kilometres away. Headteacher Alison Andreas leads a school with a capacity of 910, and in its most recent Ofsted inspection in March 2023, the school retained its Good rating, a grade it has held consistently across its previous inspection in 2017.
