External Year 12 places, GCSE thresholds and the results-day process for the girls' grammar school on Walton Road, Aylesbury.
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.
Aylesbury High School is a selective girls' grammar school on Walton Road in Aylesbury, Buckinghamshire, whose Sixth Form admits external candidates into Year 12 each September. The school's own admissions policy guarantees a minimum of 30 places for girls joining from other schools, out of 220 total Year 12 places, on a standard entry bar of 44 points from a candidate's best 8 GCSEs.
Yes. Aylesbury High School's own admissions policy states plainly that “there will be places for a minimum of 30 external girls who have fulfilled the entry requirements,” and that this figure can rise once the number of Year 11 students transferring internally is known. Those 30-plus places sit inside a total of 220 places across the whole of Year 12, alongside girls who are already on roll and simply continue from Year 11 if they meet the same entry standard.
The Sixth Form remains girls-only. Every clause governing Year 12 admission in the school's own admissions policy refers to “girls” or “she,” never to boys, and the Department for Education's Get Information about Schools register lists Aylesbury High's Gender of entry as “Girls” for the whole 11-to-18 age range, with no separate mixed-sixth-form designation of the kind some grammar schools carry. Both sources agree, and neither is silent on the point, so this is a settled fact rather than an open question.
One clarification worth making early: Aylesbury High School is not the same institution as Aylesbury Grammar School, the separate boys' grammar school also in Aylesbury. The two schools run entirely separate admissions policies, separate Published Admission Numbers and separate Year 12 application processes, though they do share some sixth-form subject teaching, covered further below.
The standard entry bar for three A-levels plus an Extension Study is 44 points from a candidate's best 8 GCSEs (or equivalent), including English Language and Mathematics, with at least grade 5 in English Language or Literature and grade 5 in Maths. On top of that general floor, each individual A-level subject sets its own minimum GCSE grade, at least grade 6 in the relevant subject, and the school's own Sixth Form Curriculum page notes that “many subjects require higher than a 6 including all Sciences.” Where a candidate has taken fewer than 8 GCSEs, the policy allows the Admission Committee to consider the case individually rather than applying the points formula mechanically.
A student who wants to take four full A-levels rather than three needs a higher bar: 64 points from their best 8 GCSEs, with at least grade 7 in each of the four subjects chosen. AHS's own Curriculum page is explicit that this is a genuinely higher standard than the three-A-level route, and it points out that “the overwhelming majority of university course entry requirements (including the most competitive) will only ask for 3 A Level grades” — worth weighing before a family pushes for the fourth subject.
What almost no published guide to this school mentions is a second, lower-threshold route written into the same policy. Up to 6 places within the 220-place PAN are reserved for candidates, internal or external, “whose GCSE or IGCSE score would not otherwise qualify them for admission” under the standard 44-point rule. This route is restricted to girls who are Looked After, Previously Looked After, Internationally Adopted, or eligible for Pupil Premium at the time of application, and it asks for 33 points from a candidate's best 6 GCSEs rather than 44 from 8 — alongside the same grade 5 English and Maths floor and the same subject-specific grade for each A-level chosen. Short-course GCSEs and resit grades do not count towards either the standard or the alternative points total. Because the eligibility criteria are specific rather than universal, this is not a general back door into Year 12; it is a targeted, materially lower bar for a defined group of applicants who might otherwise assume 44 points is the only way in — and it is worded identically in both the 2026 and 2027 versions of the school's policy, so it is not a temporary concession.
If eligible applications exceed the places available, Aylesbury High's policy applies a fixed order rather than a lottery. Places go first to Looked After, Previously Looked After, Internationally Adopted or Internationally Adopted Previously Looked After children; then to girls who qualify for Free School Meals and who have lived in the school's catchment continuously from 1 September of the preceding year; then to children of AHS staff employed for two years or more (or recruited to a shortage post); and only after those three groups are exhausted are the remaining places offered “in rank order of GCSE or iGCSE aggregate score for their best eight subjects including Maths and English.”
Where two applicants tie within any of those rules, the policy falls back on straight-line distance “between the applicant girl's home address ... and the middle of the school's main entrance gate on Walton Road,” measured using Buckinghamshire Council's own methodology, with the closest home taking priority. If two applicants live exactly the same distance from the gate, the tie is broken by random selection supervised by someone independent of the school — the only point in the entire Year 12 process where chance plays any role.
Every points threshold described above — the standard 44, the four-A-level 64, and the alternative-route 33 — is worded identically in the version of the policy covering September 2026 entry and the version covering September 2027 entry. A family comparing the two documents line by line will not find a single change to the academic bar.
What has changed is the appeals machinery around the same decision. The school's 2026 policy document records that it was determined on 6 January 2025 and then amended twice: on 17 July 2025, to extend the statutory right of appeal explicitly to Sixth Form pupils as well as parents — the policy itself confirms that “for the Sixth Form, both parents and pupils have a right of appeal where a place has been refused” — and again on 17 December 2025, to correct a misprint in the section 18 oversubscription criteria.
The 2027 policy goes a step further. It adds an entirely new paragraph, absent from the 2026 version, setting out what happens if a girl is admitted to Year 12 but then refused a place on a specific A-level course because the class is full: she can raise it with the Deputy Headteacher (Academic) first, then the Headmistress, and finally the Chairs of Governors, who confirm only whether the decision was “fair and transparent” — with the policy stating plainly that “there is no right of appeal beyond this.” For a family applying for September 2027 entry, that three-stage route did not exist in writing a year earlier.
AHS's policy fixes the shape of the application window without fixing its dates: it “opens immediately after the Sixth Form Open Evening and closes on the Monday of the first full week back following the School Christmas Holiday,” in both the 2026 and 2027 versions. The actual dates are published separately each year on the school's own How To Apply page.
For the cycle that has already run, the school's Open Evening fell on Wednesday 19 November 2025, the options-form deadline for AHS's own Year 11 students was Monday 8 December 2025, the external application deadline was Sunday 22 February 2026, families were told the outcome by Friday 27 March 2026, and external applicants attended their induction day on Wednesday 1 July 2026.
As of 22 August 2026, the same How To Apply page had not yet been updated with an Open Evening date, an application deadline or a response date for September 2027 entry — the cycle that a girl starting Year 11 this September will actually be applying under. Families planning ahead should expect the pattern above to repeat (an autumn 2026 Open Evening followed by a January 2027 deadline) but should check the school's own page directly or contact sixthformadmissions@ahs.bucks.sch.uk once the new dates are confirmed, rather than assume last year's dates carry over unchanged.
None of the pages ranking for this search carries any exam-performance data at all. The Department for Education's own performance tables, published in April 2026 for the cohort that completed Sixth Form study in summer 2025, tell a fuller story.
| Measure (2025 leavers, published April 2026) | AHS | Buckinghamshire | England |
|---|---|---|---|
| Average grade / points per A-level | B+ / 43.01 | B / 40.37 | B- / 36.1 |
| AAB+ incl. 2 facilitating subjects | 33.3% | 32.8% | 17.5% |
| Retained to end of course | 98.6% | 98.3% | 93.1% |
| Achieved an advanced maths qualification | 49.5% | 45.9% | 30.0% |
| Progressed to HE/training (2022 leavers) | 92% | 78% | 65% |
| Progressed to education/apprenticeship/employment (2023 leavers) | 91% | 85% | 79% |
212 students completed A-level study in the 2025 cohort. The progress score of -0.03 places AHS in the DfE's “average” banding rather than “above average” — a useful corrective to any assumption that a selective grammar automatically outperforms similar students elsewhere once prior attainment is accounted for, even though the school's raw grades and destinations comfortably beat both the Buckinghamshire and England averages. Ofsted's most recent inspection, on 5 December 2023, graded the whole school Outstanding and graded Sixth Form provision Outstanding separately — one of the few gradings in that report broken out by phase rather than given as a single whole-school figure.
AHS's own Sixth Form Curriculum page lists 24 different A-level subjects and 10 Extension Study options, noting that some of the 24 subjects are “offered in conjunction with our brother school AGS” — Aylesbury Grammar School, the separate boys' grammar covered above. In practice this means a handful of lower-uptake subjects are timetabled jointly across the two sites rather than duplicated in full at both schools; it does not make either sixth form co-educational, and AHS pupils remain enrolled at AHS throughout.
Admission to Year 12 is not the same as a guarantee of every subject a candidate wants. The policy states directly that a qualified girl “will, in most cases, be able to study the subjects for which she is qualified, but this will be dependent on there being sufficient places in the classes provided for each subject,” and that the school “reserves the right to refuse access to subjects when planned classes are full or where it is not viable for them to run” because too few students chose it. That is the gap the 2027 policy's new three-stage appeal route, described above, exists to address.
Families weighing Year 7 entry rather than Year 12 should see our separate Aylesbury High School 11+ page, which covers the Year 7 test format and catchment area that this page does not repeat, and our wider Buckinghamshire grammar schools guide for how AHS's Sixth Form intake compares with the county's other grammar sixth forms.
For a Year 11 student aiming at AHS's Sixth Form, the target is not vague: it is 44 points from the best 8 GCSEs (or 64 for four A-levels), grade 5 in English and Maths, and the specific subject grade — often higher than 6 — that each chosen A-level demands. Our preparation programme is built directly around those published thresholds rather than generic GCSE revision. We map a student's intended A-level choices against AHS's own subject-by-subject grade requirements and build a Year 10 and Year 11 plan around closing the exact gaps between predicted and required grades, subject by subject, well before results day decides the outcome.
For a family who may also qualify under the 33-point alternative route, we help establish eligibility early — Pupil Premium and Looked After status are assessed at the time of application, not retrospectively — so a lower headline points total is not mistaken for disqualification. One-to-one sessions run through Year 10 and Year 11 with mock assessments tracked against AHS's actual published grade table, not a generic target grade, so a family knows in good time whether they are on course for the standard 44-point route, the 64-point four-A-level route, or the 33-point alternative.
Preparing a Year 11 application for Aylesbury High School's sixth form? We build a subject-by-subject plan against AHS's own published grade table — including the 33-point route many families never hear about — so results day confirms a place rather than a surprise.

AHS's policy does not simply disqualify her. Where a candidate has not taken 8 GCSEs, the policy states that “cases will be considered on an individual basis by the Admission Committee” rather than applying the 44-point formula mechanically. The same individual-assessment principle applies to late transfers and to students with an Education, Health and Care Plan, who are also referred to the Admission Committee rather than assessed against the standard points table. There is no published formula for how the Committee weighs a shorter GCSE record, so a family in this position should contact sixthformadmissions@ahs.bucks.sch.uk directly.
AHS's policy guarantees a minimum of 30 places for external girls each September, out of 220 total Year 12 places. That figure can rise “once the number of Year 11 students transferring to Year 12 is known” — meaning if fewer of AHS's own Year 11 girls stay on than expected, more than 30 external offers can be made in that particular year. The 30-place minimum is identical in both the 2026 and 2027 versions of the policy, so it is not a number that changes year to year, only a number that can be exceeded.
Single-sex. Aylesbury High School is designated a grammar school for girls across the whole 11-to-18 age range, and every clause in its Year 12 admissions policy refers to “girls,” never boys. The Department for Education's Get Information about Schools register independently lists the school's Gender of entry as “Girls,” with no separate mixed-sixth-form category — unlike some grammar schools locally whose sixth forms do admit boys. A family should not assume AHS follows that pattern; its own policy and DfE's own record agree that it does not.
No. Nothing in AHS's admissions policy describes a sixth form entrance test or interview for either internal or external candidates. The decision rests entirely on GCSE results measured against the published points thresholds and, where oversubscribed, on the ranking criteria described above. This differs from Year 7 entry, which does involve Buckinghamshire's own secondary transfer test; Year 12 entry at AHS does not carry an equivalent assessment.
Aylesbury Grammar School (AGS) is a separate, boys-only grammar school in Aylesbury with its own headteacher, its own admissions policy and its own Published Admission Number for Year 12 — AGS's own site states a minimum of 17 external sixth-form places, compared with AHS's 30. AHS describes AGS as its “brother school” because some A-level subjects are timetabled jointly across the two sites, but the two remain entirely separate institutions with separate applications; a family should not apply to one expecting it to cover the other.
Parents have a statutory right to appeal a refusal to an Independent Appeal Panel, which Buckinghamshire Council manages on the school's behalf, and — specifically for the Sixth Form — the policy confirms that “both parents and pupils have a right of appeal where a place has been refused,” wording added by amendment on 17 July 2025 to make clear the pupil herself can appeal, not only her parents. This is separate from the newer, narrower course-allocation appeal described above, which applies once a girl has already been admitted but is refused a specific A-level class.
Not yet published, as of 22 August 2026. The school's own How To Apply page still showed the previous cycle's dates — an Open Evening on 19 November 2025 and an application deadline of 22 February 2026 — with nothing yet listed for September 2027 entry. Based on the pattern set out in the policy, the window should open immediately after the next Sixth Form Open Evening, expected in autumn 2026, and close on the Monday of the first full week back after the Christmas holiday, likely early January 2027; families should confirm the exact date directly with the school.
No. AHS's policy is explicit that admission to Sixth Form “is not admission to a guaranteed course of study,” and that a subject place depends on “there being sufficient places in the classes provided for each subject.” Under the 2027 policy, a girl refused a specific subject can raise it with the Deputy Headteacher (Academic), then the Headmistress, and finally the Chairs of Governors — a three-stage route that did not exist in writing under the 2026 policy.
