Overview

A selective boys grammar school in Essex with mixed sixth form entry, strong academic outcomes, and established Oxbridge and Russell Group progression. Based in Colchester, Essex, the school serves boys aged 11-18 and includes sixth-form study as part of the offer. Current published roll and admissions data point to around 1,059 pupils on roll and 128 Year 7 places. The school also has a Christian character, which can matter for families thinking about ethos as well as academic fit. It is also recorded as a boarding school, which is a relatively unusual feature in the grammar-school sector.

Admissions are central to understanding whether this school is the right fit and realistic shortlist option. The current route includes CSSE, with 128 places available in Year 7 and roughly 6.1 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.

Academically, the published picture is strong and easier to judge than reputation alone. Recent official performance measures show Progress 8 at 1.09 and Attainment 8 at 83.4. 100% of pupils achieved grade 5 or above in English and maths in the latest stored GCSE figures. In the sixth form, 77.7% of entries were awarded AAB or better at A level.

Published school information highlights facilities such as Library. The wider offer currently includes Orchestra, Choir, Drama. 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. That mix of selective entry, published outcomes, and school life is what will matter most to families deciding whether Colchester Royal Grammar School belongs on a serious shortlist.

Pass mark note
CSSE does not make selective offers below a total standardised score of 303. At CRGS, Priority 1 places require a score above 320, and the lowest published National Offer Day score for September 2025 entry was 343.

CRGS has no priority area. Applicants must register with CSSE by the official deadline and name CRGS on the home local authority application by 31 October 2026; Priority 1 is limited to looked-after or pupil-premium boys scoring above 320 before remaining places are allocated by score rank.

CRGS has no priority area. Offers are made in score order, with straight-line distance used only to break tied scores.

Oversubscription and eligibility

  1. 1

    Up to 12 places for looked after and previously looked after boys scoring above 320.

    Priority 1 first considers looked after and previously looked after applicants who name CRGS and meet the score threshold.

  2. 2

    Any remaining Priority 1 places then go to eligible pupil premium boys scoring above 320.

    Pupil premium eligibility must be declared during the CSSE registration process and confirmed if requested.

  3. 3

    All remaining places are offered in descending score order until the PAN of 128 is filled.

    CRGS has no priority area, so the main allocation is score-based rather than catchment-based.

  4. 4

    Tied scores are separated by looked after status, pupil premium, then straight-line distance.

    If scores are tied for the final place, the school applies its published tie-break sequence.
