Latest Advice:

A Guide to Beaconsfield High School Admissions

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.

A Guide to The Judd School Admissions

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.

A Guide to Dr Challoner’s High School Admissions

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.
