High-performing state-funded grammar schools are not limited to Kent. Buckinghamshire, which retained its grammar schools during the government closures of the 1960s and 1970s, is home to an impressive number of excellent schools. Four of the county鈥檚 state schools ranked in the top ten in the South East of England in the Even more notably, these same schools are among the top fifty nationally, across primary, secondary, and independent sectors.
Among them, 鈥� known locally as 鈥淏ecky High鈥濃�� stands out for its exceptional academic results. Yet, reviewers describe the all-girls school as a calm, approachable, and welcoming environment. Students are reportedly happy, motivated, and proud of their school, with a strong work ethic.
A 2024 Ofsted inspection rated Beaconsfield High as Outstanding, highlighting that its achievements extend beyond exam performance. Ofsted praised the school for fostering 鈥渃haracter and becoming a rounded individual,鈥� noting its wide-ranging extracurricular opportunities, particularly in the performing arts.
Academic results are consistently impressive. At A Level, half of all grades were A or A*, with 43 students achieving straight A*/A across three or four subjects, and 56 students earning at least one A* grade. At GCSE in 2025, 23% of grades were Level 9, and 50% were Levels 8 and 9. Overall, 71% of results were Level 7 or above, and 90% of students achieved Level 6 or higher.
Entry Points
The school has two standard entry points, in Year 7 and Year 12. Each year around 180 girls are admitted into Year 7, with 30 places offered to external candidates for Sixth Form study.
Irregular applications for Years 8, 9 and 10 should be made directly to Buckinghamshire Council. Those looking for admission into Year 10 are required to pass assessments in English, Maths, Science, as well as a choice of Language from French, Latin or Spanish.
Admission Requirements for 11+ Entry
Admissions for Beaconsfield High School are managed by Buckinghamshire Council, who administer what is known as the (STTS), details of which are provided below. Girls will be considered for admission at 11+ if they meet the necessary qualifying mark of 121 across the two papers of the test. Girl鈥檚 scores are age-standardised to make sure that all students are put on an equal footing, regardless of their exact date of birth.
The council suggests that all students who meet the STTS minimum score of 121 will qualify automatically for a grammar school spot. However, as schools will invariably be oversubscribed, the oversubscription criteria will normally be applied and not all students will get into their school of first choice. In the case of Beaconsfield, the oversubscription criteria set out quite strict terms 鈥� and arguably quite democratic or at least localist terms, at least if you live in Buckinghamshire.
In summary, the oversubscription criteria at Beaconsfield High School dictate that girls who are technically Looked After, or have an entitlement to the Pupil Premium - and who live in the catchment area 鈥� will be the first to be allocated at place at the school, even if they have not quite made the 121 mark. Thereafter the sisters of existing pupils are considered before the school turns to admitting girls from within the given catchment area. Only then will the school turn to students not from within the immediate area.
Tests take place in early-mid September and those of an appropriate age attending Buckinghamshire primaries will be tested in their schools. Those attending other schools sit the test at a Buckingham grammar, or another central test venue.
