Overview

A selective girls grammar school in Colchester, Essex, serving ages 11-18 with a sixth form and around 1,210 pupils on roll. Colchester County High School for Girls serves girls aged 11-18 and keeps a full sixth form on site. Current published roll and admissions data point to around 1,210 pupils on roll and 192 Year 7 places.

From a family point of view, admissions are likely to be one of the most important parts of the picture. The current route includes CSSE, with 192 places available in Year 7 and roughly 3.8 applicants per place in the latest stored admissions picture. Catchment or distance rules still matter at allocation stage, so this is the kind of school where families need to read the admissions policy carefully rather than rely on headline scores alone.

The academic side of the school is backed by enough published data to give families a useful starting point. The latest published Ofsted judgement is Outstanding. Recent official performance measures show Progress 8 at 0.99 and Attainment 8 at 80.8. 99.4% of pupils achieved grade 5 or above in English and maths in the latest stored GCSE figures. In the sixth form, 44% of entries were awarded AAB or better at A level. Destinations data also suggest strong progression after sixth form, with 76% moving into higher education.

Published school information highlights facilities such as Library. For many parents, the presence of a sixth form is part of the attraction, because it gives able pupils the option to stay in a familiar academic setting through to A level. Taken together, those features make Colchester County High School for Girls the kind of school that rewards careful research into travel, admissions detail, and day-to-day fit, not just headline outcomes.
