Buckinghamshire is one of the few English counties to have retained a fully selective grammar school system and is home to a number of outstanding state-funded schools that consistently rival the independent sector for academic results. However, while this education is free at the point of access, securing a place is highly competitive and often demanding for both pupils and parents. The county is widely regarded as an environment that attracts ambitious families and academically driven children.

Sir William Borlase’s Grammar School is a co-educational grammar school which, in the past, was sometimes perceived as elitist or overly pressurised. Current parental opinion suggests that this reputation no longer reflects the school’s ethos. This view is strongly supported by the most recent Ofsted inspection (2024), which judged the school to be Outstanding in all areas. The report highlights that the school’s excellence is rooted not only in academic outcomes, but also in the strength of its provision for personal development. Ofsted notes that, “The impressive extra-curricular programme … allows pupils to enrich their learning outside the classroom but also to develop and discover interests and talents.” Teaching was rated as exceptional, with staff commended for delivering an ambitious and broad curriculum, including strong provision for pupils with SEND.

These strengths are complemented by a distinctive and inspiring setting. Founded in 1624, the school continues to occupy its original site, where brick-and-flint cloisters, a clock tower and a chapel provide a tangible sense of history. These historic features sit alongside modern facilities, including the 2021 Sports Hall and other recent developments, creating a learning environment that successfully blends tradition with innovation.

The Judd School is a selective, state-funded grammar school, based in Tonbridge in Kent. Established in 1888, the school admits boys from Year 7 to Year 11, and the Sixth Form is co-educational. 

Academics-wise, The Judd School has a reputation as being one of the strongest in the county. In the most recent academic year, around 83% of pupils scored between an A* and a B at A Level, which was one of the highest in the county. Top Russell Group universities such as Bristol, Durham and Oxbridge frequently feature on boys’ destination lists, while an increasing number of students accept prestigious apprenticeships. 

Outside of academics, The Judd School also offers a wide variety of extracurricular activities. The campus is a blend of traditional grounds and more modern, purpose-built facilities. Sports-wise, the school owns a site called Vizards, which is around 900 metres from the school, and it contains a 3G rugby pitch, 4 full-size football pitches (which can be converted to 5 full-size rugby pitches), as well as 2 grass cricket squares. On-site, there is a sports centre, which includes facilities for basketball, badminton and volleyball, as well as an all-weather pitch and multi-use games area outside. There is a wide range of clubs and societies on offer, such as Potions Club, Medical Society and Gardening Club, as well as facilities for the arts, including music practice rooms and recording facilities. 

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’s state schools ranked in the top ten in the South East of England in the Sunday Times Parent Power survey. Even more notably, these same schools are among the top fifty nationally, across primary, secondary, and independent sectors.

Among them, Beaconsfield High School — known locally as “Becky High”— 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 “character and becoming a rounded individual,” 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.

Like Kent, Buckinghamshire retained its grammar schools when selective state education was phased out elsewhere in the UK. The county is home to some of the country’s top state-funded secondary schools. Dr Challoner’s High School, alongside its local counterpart Beaconsfield High School, forms a powerhouse of selective state education that rivals the best in the nation, whether state or independent.

Exam results at Dr Challoner’s are consistently outstanding, and the school is highly oversubscribed. Students develop a reputation locally for being confident and well-rounded, thanks in part to the wide range of extracurricular opportunities available.

In recent years, Dr Challoner’s High School has been named the best secondary school in Buckinghamshire, despite strong competition from other local grammar schools. This ranking is based on Key Stage 4 performance, particularly the number of students achieving strong passes (Grades 9–5) in English and Mathematics. In 2025, 99.5% of students achieved a strong pass, an almost perfect result. That year also saw the best results in the school’s history, with 83% of all grades at 7, 8, or 9.

A-Level results in 2025 were also record-breaking: 56% of all grades were A* or A, 83% were A*–B, and 95% were C or above. Record numbers of students secured places at their university of choice.

Common FAQs on Working with an Education Consultant 

The decision on where your child should go to school or university is a critical one, and can be exciting, complicated, and even a little overwhelming for any parent.  

It can be the culmination of years of your child’s hard work and careful planning, and can open up avenues for their education and career that enable them to flourish – or close them off. Top independent schools and world-class universities can have idiosyncratic admissions processes and challenging criteria, which can make an application even more complex and stressful. To top it off, if your child is also applying to a school or university in a different and unfamiliar country, perhaps because your family has relocated, an additional layer of problems and questions can arise.

How can you and your child make a more informed and ultimately more successful decision? How can you make the application process more transparent and easier to navigate? An Education Consultant could provide the professional expertise you need.

In recent years, many independent senior schools that have put pre-tests in place have purposefully designed them with as little transparency as possible. It is for this reason that the tests are often computer generated and no past papers are issued. As such, no tutor can claim to have in depth knowledge or experience of the tests themselves, in their current form.

For schools following the Pre-Assessment route, children will usually be asked to sit a Pre-Test in Year 5, 6 or 7 (Year 6 is the norm).
