Up to 50 external places each September, decided on GCSE grades alone — how to meet CCHSG's entry bar
Book a Free ConsultationMy son was low in confidence after COVID and the gaps in learning were building up. Using this service helped plug those gaps, rebuild confidence, and improve his ability to learn properly again.
We arranged maths and English tuition ahead of GCSEs and both tutors were brilliant. My daughter's grades improved, and by results day she achieved two grades higher than in her mock exams.
I attended an English bootcamp with Leading Tuition and the experience was excellent. The teacher gave focused attention to the small group while keeping the lessons interactive and engaging.
Colchester County High School for Girls (CCHSG) is a super-selective girls' grammar school in Colchester, Essex, that admits up to 50 external candidates into Year 12 each September, alongside girls progressing from its own Year 11. Entry is decided entirely on GCSE results: a minimum of four grade 7s and two grade 6s, including grade 6 or above in English Language and Mathematics. There is no catchment test, no selection interview, and the sixth form remains girls-only.
CCHSG's Year 7 admissions run on a 25-mile priority area that fills the majority of its Year 7 places by score and postcode — the subject of our separate CCHSG 11+ preparation guide. Sixth form entry drops that geography test entirely. The school's own admissions policy for 2026–2027 entry states plainly that "the priority area criteria does not apply to the Sixth Form", which means a girl living forty miles away with the right GCSE grades competes on exactly the same footing as a girl living streets from the school gates.
The only geographic factor that survives into sixth form is a tiebreaker of last resort: where two candidates have identical GCSE point scores and are competing for the last place on a specific subject combination, the place goes to whoever lives nearer the school by straight-line measurement. Short of that scenario, address plays no part in whether an external application succeeds.
The headline bar is four GCSEs at grade 7 or above and two at grade 6 or above, which must include English Language and Mathematics at a minimum of grade 6. On top of that floor, CCHSG requires at least a grade 7 in each individual GCSE subject a candidate wants to carry into the same subject at A Level — a grade 6 in GCSE Biology, for instance, clears the general floor but is not on its own enough to start A Level Biology. Six subjects carry an additional or substitute requirement where the A Level is not a direct GCSE continuation:
| A Level subject | Additional GCSE / other requirement |
|---|---|
| Further Mathematics | Grade 8 or above in GCSE Mathematics |
| Psychology (not taken at GCSE) | Grade 7 in GCSE English Language or Literature, and Grade 6 in Mathematics |
| Physical Education | Grade 7 in GCSE Biology, plus competing at a high level in an AQA-recognised sport outside school |
| Music | Standard GCSE bar plus ABRSM Grade 5 Music Theory and Grade 5 Music Practical |
| Classical Civilisation / Economics / Religious Education (not taken at GCSE) | Grade 6 in GCSE English Language or Literature |
| Computer Science (not taken at GCSE) | An equivalent Level 2 IT or Computer Science qualification |
These are minimum thresholds, not guarantees of a place. CCHSG's own policy is explicit that meeting the grade criteria "does not guarantee a place on any course or combination of courses", because subject offers also depend on how many students want each combination and how large the resulting teaching groups would be — the school reserves the right not to run a subject at all where a group would not be financially viable.
Search this question and you currently get two different answers. Google's AI Overview states that CCHSG "admits external students of all genders to its sixth form", and the competitor admissions guide GrammarBound goes further, writing that sixth form entry "is open to all genders, not just girls." Neither claim matches what the school has actually published. Section 2.1 of CCHSG's own A1 Admissions Policy for 2026–2027 caps the external intake at "a maximum of 50 girls joining from other schools" — the word used, twice in that sentence, is girls, and every reference to applicants throughout the sixth form section of the policy uses female pronouns.
Colchester County High School for Girls is a single-sex school from Year 7 through to the end of Year 13; it has not converted to co-educational sixth form entry, unlike some neighbouring grammar schools that do admit the opposite sex at 16+. Families weighing CCHSG for a son should treat the AI Overview summary as incorrect and confirm directly with the school's admissions office on 01206 576973 before assuming a place could be available to him.
CCHSG expects more qualified applicants than it has room for, and says so directly: "more conditional places will be offered than places available as some applicants will not achieve the minimum entry criteria or will decide to attend an alternative Sixth Form provider." Where a subject or the sixth form as a whole is oversubscribed, places go out in a fixed order:
An external candidate from outside the Alpha Trust group is therefore last in the queue, behind CCHSG's own Year 11 leavers and behind pupils from its trust's other secondary schools. Within each of those four groups, places are confirmed in descending order of average GCSE point score across a candidate's best eight full-course GCSEs — including English and Mathematics — using CCHSG's own points scale (A* = 8.5, A = 7, B = 5.5, C = 4; anything below a C or 4 does not count). Where two candidates tie on points and are competing for the same subject combination, the deciding factor is straight-line distance from home to school — the one place in the whole sixth form process where geography still plays a role, and only as a tiebreaker of last resort.
Because offers are conditional on GCSE grades not yet achieved, CCHSG runs a tight verification process on results day itself. Both internal and external candidates must have their results checked in person, and the policy is specific that "external candidates will be required to bring their results to the school on results day" — a printed slip sent by post or email first is not accepted in its place. Once verified, confirmed places are communicated by email within five working days of results being published.
From that point the clock runs the other way: a candidate offered a confirmed place after results day has to accept within 48 hours, after which — CCHSG's policy states without qualification — "the offer of place will be withdrawn." Places are also confirmed strictly on the results published that day; the school will not hold a place open while an Enquiry About Results (a re-mark) is pending, so any resit or remark strategy has to be planned before the summer, not after. One further rule catches some families out: a candidate must be under 17 years of age on 31 August of the year she is due to start, which can rule out sixth form entry for a candidate whose GCSEs fall outside the normal Year 11 timetable.
International applicants and those moving from schools that don't offer GCSEs are not automatically excluded. CCHSG's policy sets out a specific route: "where students applying to the Sixth Form do not have GCSE or IGCSE qualifications, applications are considered on an individual basis and will involve the candidate taking a test for each A Level subject set by the Head of Department." The school also weighs whatever other information the candidate's current school can provide alongside that test result.
Where English is not a candidate's first language, CCHSG may separately ask her to demonstrate fluency in both spoken and written English before a place is confirmed — a step that sits alongside, not instead of, the academic requirements described above.
For a family weighing whether the application effort is worthwhile, CCHSG's most recently published outcomes give a clear answer. In the 2025 A Level results, 125 students sat A Levels at the school.
| 2025 A Level outcome | Percentage of grades awarded |
|---|---|
| A* grades | 23% |
| A*–A grades | 58% |
| A*–B grades | 83% |
Mathematics was the single most popular subject by entries in 2025, followed by Biology and Chemistry — reflecting the STEM-heavy cohort that CCHSG's grade-7-per-subject entry bar tends to select for. These figures sit well above typical national averages for A*–B grades, and they are the clearest evidence that the entry bar described above is not simply a hurdle for its own sake: CCHSG's own outcomes data shows the great majority of students who meet it go on to achieve strong final grades.
CCHSG's entry bar is unusual in how granular it is: a general four-grade-7 floor, then a second, subject-specific bar layered on top for Further Maths, Psychology, PE, Music and three other subjects. Leading Tuition's preparation for CCHSG applicants is built around that structure rather than a generic GCSE revision programme, because a strong overall GCSE profile is not automatically the right profile for this particular school.
For a student targeting Further Mathematics, that means specialist Further Maths tuition aimed specifically at the grade 8 threshold in GCSE Mathematics — a full grade above the general floor, and the single hardest individual bar in CCHSG's policy. For a student targeting Psychology, PE or one of the other subjects with a substitute entry requirement, we build the relevant English, Mathematics or Biology grade into the programme early, because those subjects' requirements are set well before the student ever sits an A Level paper. Across every subject, our tutors work from CCHSG's own grade-7-per-chosen-subject rule rather than a general "aim high" target, so a student and her parents know exactly which grade in which subject unlocks which A Level.
Because CCHSG's Head of Sixth Form asks the current school for predicted grades before making a conditional offer, our GCSE tuition also focuses on the mock exam windows that generate those predictions, not just the final summer papers — a strong November or February mock matters for this application in a way it might not for a school that only looks at final results. And because acceptance of a confirmed place is a 48-hour window on results day itself, we prepare families for that day specifically: what to bring, how the in-person verification works, and what a realistic Plan B looks like if a single grade falls short, including the timing constraints around Enquiry About Results.
For applicants without GCSE or IGCSE qualifications — often international families — our A-Level tuition team also prepares students for the Head of Department subject tests that CCHSG sets in place of a GCSE record, working from past-paper-style material in the specific subjects a student intends to study.

Book a Free Consultation Message us on WhatsAppYes. CCHSG admits up to 50 girls from other schools into Year 12 each September, alongside those progressing from its own Year 11. Applications go directly to the school rather than through the local council's admissions process used for Year 7. Entry is decided on GCSE results alone: a minimum of four grade 7s and two grade 6s, including English Language and Mathematics at grade 6 or above, with a grade 7 required in each subject a candidate wants to study at A Level. There is no interview and no catchment requirement for external Year 12 entry.
The general floor is four GCSEs at grade 7 or above and two at grade 6 or above, including English Language and Mathematics at a minimum of grade 6, plus at least a grade 7 in each subject you want to study at A Level. Several subjects carry a further requirement: Further Mathematics needs grade 8 in GCSE Mathematics, A Level PE needs grade 7 in GCSE Biology, and A Level Music needs ABRSM Grade 5 Theory and Grade 5 Practical alongside the standard GCSE bar.
No. CCHSG's Year 7 admissions use a 25-mile priority area that fills the majority of its Year 7 places by postcode, but its own admissions policy states plainly that the priority area criteria does not apply to the Sixth Form. External Year 12 applicants are judged on GCSE results alone, whatever their home address. The only place geography reappears is as a tiebreaker of last resort, when two candidates have identical GCSE point scores and are competing for the final place on a specific subject combination.
No. Despite claims from Google's AI Overview and at least one third-party admissions guide that CCHSG sixth form is open to all genders, the school's own A1 Admissions Policy for 2026-2027 caps external Year 12 entry at a maximum of 50 girls. CCHSG is a single-sex girls' grammar school from Year 7 through to the end of Year 13 and has not introduced co-educational sixth form entry. Families should verify directly with the school's admissions office on 01206 576973 rather than relying on AI-generated search summaries.
Not as part of the formal selection process. CCHSG's policy states that applicants may be invited into school for a discussion centred on their future career plans and to confirm their final requested A Level subject choices, but adds explicitly that the meeting will not form part of the selection process. The exception is a candidate without GCSE or IGCSE qualifications, who sits a subject-specific test set by the relevant Head of Department instead.
CCHSG verifies GCSE results in person on results day itself, and confirmed places are emailed within five working days. If a conditional offer isn't met, the place is not automatically held: the policy does not allow a place to be kept open while an Enquiry About Results is pending, so any resit or remark plan needs to be arranged before results day, not after. A candidate who is offered a confirmed place after results day then has only 48 hours to accept it before the offer is withdrawn.
Up to 50, according to CCHSG's own admissions policy, a cap shared across every subject and combination rather than a guarantee for any individual applicant. The school issues more conditional offers than the 50 places it expects to fill, because some offer-holders will not meet the grade requirements and others will choose a different sixth form. Where demand exceeds supply, external applicants from outside the Alpha Trust group are ranked behind CCHSG's own Year 11 leavers and behind pupils transferring from the trust's other secondary schools.
The Open Evening for entry to Year 12 in September 2027 is scheduled for Wednesday 21 October 2026, from 18:00 to 20:30. The school states that booking is not required and that the sixth form will be open for tours, with staff and current students available to discuss subject choices. This is the main opportunity for external Year 11 applicants to see the sixth form in person before deciding whether to apply.
