An all-round, unpressured but effective education providing an interesting range of sixth form options to a wider ability range with a top-class equestrian offer thrown in – Stonar gets red rosettes all round. ‘So happy we found it and wish we had done so in time for our older boys,’ one delighted mother told us. We watch with interest as this school continues to redefine its image without losing its charm or USP.

Very few leave at year 6 (but the occasional one to local state schools): 90 per cent of prep school pupils go on seamlessly to the senior school. Any necessary conversations about not moving on are held with plenty of warning in year 4. Around 20

Teaching & learning

The prep school curriculum is delivered through topic-based learning covering all main subjects: each term the pupils explore an enquiry question, which starts with the knowledge they already have. Gasps of breath and a forest of hands rewarded an

Arts & extracurricular

You don’t have to ride at Stonar, despite appearances: it’s firmly extracurricular, though there is little escaping its prominence. The lucky prep school children get two doses of art, one as part of their cross-curricular learning and the other as a

Founded in 1895, but on the Kent coast. Like so many schools, the Second World War had a profound effect on the school’s history, causing a forced move to its current home, Cottles Park, after its original home was requisitioned by the Ministry of

What is this?

Facilitating A levels are ones that are commonly needed for entry to leading universities. They are: biology, chemistry, physics, mathematics, further mathematics, geography, history, English literature and classical or modern languages. The % of pupils achieving AAB or higher may therefore decrease if many pupils have opted not to take two or more of the facilitating subjects mentioned.
