Fifty external places, the GCSE grade bar and the shared Poole Grammar sixth-form curriculum, explained.
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.
Parkstone Grammar School is a selective girls' grammar in Poole, Dorset, that opens 50 of its Year 12 places each September to external applicants who were not on its own roll at 11. For September 2027 entry, external candidates need six GCSEs, including grade 5 or above in Mathematics and grade 4 or above in English Language, alongside a broader curriculum shared with the neighbouring boys' grammar, Poole Grammar School.
Parkstone's determined admissions policy for September 2027 entry states plainly: "50 girls can be accepted into the Sixth Form from other schools." The same sentence, with the same figure, appears in the school's separately published September 2026 policy. That stability matters, because it means a family planning two years ahead is not guessing at a number that might move: the external Year 12 published admission number has held at 50 across both determined cycles.
That external allocation sits alongside Parkstone's Year 7 published admission number of 192, so the sixth-form external route is a much smaller, separately governed intake, roughly a quarter the size of the main point of entry. Parkstone's own Year 11 students are not competing against those 50 places at all: the policy gives any Year 11 girl who meets the grade requirement an automatic right of entry to Year 12, so the external places exist purely to top up the cohort from outside.
Not sure whether a grade 5 Maths GCSE is realistic by results day? A short diagnostic session shows exactly which topics are costing marks and how much runway is left before the results that decide a September 2027 place.

The Consortium is an admissions arrangement, and it stops at age 11. Bournemouth School for Girls' own 2027 admissions policy states it directly: "There is one set of selection tests for Bournemouth School For Girls, Bournemouth School, Parkstone Grammar School and Poole Grammar School (the 'Consortium'). Whilst the testing procedures are shared, each school is its own admissions authority (with its own admissions policy and over-subscription criteria)." At sixth form, that shared testing disappears entirely. There is no joint Year 12 assessment. Parkstone judges its own 50 external places purely on GCSE results, under its own oversubscription order, with no reference to what Poole Grammar or Bournemouth School for Girls decide.
The partnership is a different thing altogether: a teaching arrangement, specific to Parkstone and Poole Grammar, that only begins once a student is already enrolled. Ofsted's May 2025 inspection of Parkstone describes it in the school's own operating terms: "The school partners with the local grammar school for boys to offer a broad curriculum in the sixth form. Some students travel between sites to attend their courses." A girl admitted to Parkstone's sixth form is admitted to Parkstone, full stop; the shared lessons are a curriculum benefit that follows admission, not a joint application route into it. She keeps her Parkstone registration and lanyard throughout, even on the days her timetable sends her to Poole Grammar's site.
DfE's Get Information About Schools record lists Parkstone's "Gender of entry" as Girls, but that field describes the age-11 intake specifically and was never designed to answer a question about who can join at 16. Ofsted's inspection reports carry a separate, purpose-built field for exactly this: "Gender of pupils in sixth-form provision." Parkstone's most recent inspection, dated 20 and 21 May 2025, records that field as "Girls." The school's own determined admissions policy is consistent with it throughout, referring to "eligible girls" at every stage of both the internal and external Year 12 routes.
One directory site found during research, Pass Eleven Plus, states that Parkstone's sixth form is "mixed, welcoming both girls and boys." Checked against Ofsted's field and the school's own policy on 22 August 2026, that claim does not hold up. For comparison, Poole Grammar's own most recent Ofsted inspection, dated 26 and 27 March 2024, records its sixth-form gender field as "Boys." Both schools, checked the same way, stay single-sex at 16, not just at 11 -- which is also why the shared curriculum between them is a teaching arrangement between two single-sex sixth forms, rather than a merger of the two into one mixed intake.
Parkstone's requirement is specific rather than a general pass rate. Mathematics must sit at grade 5 or above. English is satisfied either through English Language at grade 4 or above, or through English Literature provided English Language itself still clears grade 4. The remaining four GCSEs, to make six in total, must fall at grades 5 to 9. On top of that six-subject floor, the school layers "an acceptable grade in the subjects chosen at advanced level or in a related subject," set out year by year in the Sixth Form Prospectus rather than in the admissions policy document itself.
None of this shifted between the September 2026 and September 2027 determined policies -- the wording is identical in both. A Year 11 student at Parkstone who reaches this bar has an automatic place; an external applicant who reaches it is eligible to be considered under the oversubscription order below, but reaching the grade floor alone is not, by itself, a guarantee of a place if the 50 spaces are oversubscribed.
Parkstone's policy sets out a fixed ranking, applied only once the school has more eligible external applicants than the 50 places available. The order runs: first, eligible girls with an Education, Health and Care Plan; second, eligible girls who are, or were previously, "Looked After"; third, eligible girls entitled to Pupil Premium, with documentary evidence required; and fourth, all other eligible girls. Within any one of those four groups, if there are still more applicants than places, Parkstone breaks the tie by the QCA average points score across a candidate's best eight GCSE results -- meaning two girls who both clear the grade 5 Maths and grade 4 English floor are not treated identically if one has the stronger overall Key Stage 4 record once all eight subjects are counted.
Poole Grammar's own "Poole and Parkstone Shared A-Level Courses Student Guide," published for the 2025-26 academic year, names eleven subjects taught jointly across the two schools. Eight of them are delivered at a single site, and for most of these eight the site is Parkstone itself: Art and Design (Graphics), DT Product Design, English Language, English Literature, German, Media Studies, Psychology and Sociology. A student on any of these eight subjects does not travel between schools for that lesson, whichever school she is registered at.
The remaining three subjects, French, Spanish and Theatre Studies, are taught across both sites, with a different named member of staff running each school's own group. A student choosing one of these three will move between Parkstone and Poole Grammar during the week for that subject specifically, not for her whole timetable. The guide sets out the mechanics precisely: the shared year begins with a joint Year 12 induction session at Poole on the first Thursday of September, students sign in and out at reception using an electronic terminal when on the other site, and a Parkstone student wears her own school's lanyard throughout, even while sitting in a Poole Grammar classroom. The two schools also hold joint parents' evenings and run slightly different bell times, so a student's day genuinely changes shape depending on which site a given lesson falls on.
The three schools that sit alongside Parkstone in the wider Poole and Bournemouth grammar group each publish their own sixth-form entry bar, and it is worth being precise about the fact that these three figures are not built the same way. Forcing them into a single ranked list would flatten a real structural difference rather than describe it.
| School | Sixth-form gender | External GCSE requirement | Basis | External PAN |
|---|---|---|---|---|
| Parkstone Grammar School | Girls | Maths grade 5+; English Language grade 4+; four further GCSEs at grades 5-9 | Fixed per-subject minimums | 50 |
| Bournemouth School for Girls | Girls | All six GCSEs at grades 6-9; English Language/Literature and Maths at grade 4+ | Fixed per-subject minimums, higher floor | 60 |
| Poole Grammar School | Boys | Mean grade 5.5 across best 7 GCSEs; English and Maths at grade 5+ | Average across best seven, a different measure | 30 |
Parkstone and Bournemouth School for Girls both work on fixed per-subject minimums, which makes them the closer comparison of the three, and on that measure Bournemouth School for Girls sets the higher floor: every one of its six GCSEs must clear grade 6, where Parkstone only requires that of Maths at grade 5 and lets four of the remaining subjects sit as low as grade 5. Poole Grammar's mean-grade-5.5-across-best-seven system is a genuinely different calculation, an average rather than a set of individual floors, so a candidate could clear Poole Grammar's bar with one weaker GCSE offset by stronger results elsewhere in a way that neither Parkstone's nor Bournemouth School for Girls' system permits. Each figure above is sourced to that school's own determined admissions policy, not to any other school's page describing it.
Parkstone's Sixth Form Open Evening for prospective external applicants is confirmed for Thursday 22 October 2026, running 6pm to 8pm. The school's determined admissions policy for September 2027 entry carries an approval date of November 2025, from its Standards and Safeguarding committee. Subject-specific entry requirements, updated for the current cycle, sit in the Sixth Form Prospectus, linked from the curriculum section of Parkstone's own sixth-form pages rather than published inside the admissions policy document itself. Families weighing up a place should treat the GCSE results in August 2027 as the point every one of the figures on this page ultimately turns on: the grade floor, the oversubscription order and the 50-place ceiling all apply to results achieved by then, not to predicted grades set earlier in Year 11.
Leading Tuition works with students preparing for exactly this kind of grade-specific bar, where a single subject, most often Mathematics, sits between a Year 11 student and an automatic place, or between an external applicant and eligibility for one of Parkstone's 50 places. Support is built around the actual thresholds a school publishes rather than a generic GCSE revision programme, using GCSE tuition to close a specific grade gap and A-level tuition once a student has been offered a place and needs a head start on the subjects Parkstone's own Maths tuition and sciences departments will expect. Families further back in the process, still deciding between Parkstone and the wider Poole and Bournemouth grammar group, may also find our guide to Bournemouth School for Girls' own sixth-form entry useful for a direct, separately sourced comparison, and our existing Parkstone Grammar 11+ guide covers the Year 7 entry route in full for families with a younger daughter as well.

Both. Parkstone's own Year 11 students transfer automatically once they meet the grade requirement, and the school separately opens 50 places to external candidates for September 2027 entry, exactly the same figure set for September 2026. That external number sits alongside a Year 7 published admission number of 192, so the sixth form intake is a much smaller, separately governed cohort. Applications are made directly to Parkstone, not through a shared consortium process.
No. One directory site, Pass Eleven Plus, states that Parkstone's sixth form is "mixed, welcoming both girls and boys." Checked against two primary sources on 22 August 2026, that is incorrect: Ofsted's own inspection field for the school records "Gender of pupils in sixth-form provision: Girls," and Parkstone's determined admissions policy refers throughout to eligible girls for both the internal and external Year 12 routes. Poole Grammar, the neighbouring boys' school, records "Boys" in the same Ofsted field, so the pairing stays single-sex at 16.
Grade 5 or above, non-negotiable, under both the September 2026 and September 2027 determined admissions policies. English Language also has a set floor of grade 4 or above, or grade 4 in Language alongside a pass in Literature. The remaining four GCSEs of the required six must sit at grades 5 to 9, with subject-specific minimums layered on top for whichever A-levels the student wants to study, published in Parkstone's own Sixth Form Prospectus rather than the admissions policy itself.
Parkstone ranks applicants through a fixed order rather than a lottery. Girls with an Education, Health and Care Plan are placed first, then those who are or were previously Looked After, then those eligible for Pupil Premium, then all other eligible girls. Within any one of those groups, a tie is broken by the QCA average points score across a candidate's best eight GCSE results, so two girls who both clear the grade floor are not treated as equal if one has a stronger overall Key Stage 4 record.
No. Of the eleven subjects taught jointly, eight are delivered at a single site, mostly Parkstone itself: Art and Design (Graphics), DT Product Design, English Language, English Literature, German, Media Studies, Psychology and Sociology. Only French, Spanish and Theatre Studies are taught across both sites with separate teaching staff at each, so a Parkstone student on one of those three courses travels to Poole Grammar for some lessons while remaining registered and administered at Parkstone throughout.
Only at age 11. Bournemouth School for Girls' own 2027 admissions policy confirms that Bournemouth School for Girls, Bournemouth School, Parkstone and Poole Grammar share one set of Year 7 selection tests as "the Consortium," while each remains its own admissions authority with its own criteria. That shared arrangement stops at 16: there is no joint sixth-form test, and Parkstone's 50-place external route is assessed on GCSE results alone, entirely separately from Poole Grammar's or Bournemouth School for Girls' own sixth-form policies.
The three are not built the same way, so a direct ranking would be misleading. Parkstone sets fixed per-subject minimums: grade 5 in Maths, grade 4 in English Language, and grades 5-9 elsewhere. Bournemouth School for Girls sets a higher fixed floor, grade 6 across all six GCSEs. Poole Grammar instead uses an average, a mean grade of 5.5 across a candidate's best seven GCSEs, plus grade 5 in English and Maths specifically, which is a genuinely different measure from either fixed-floor system.
