No longer your backup, Aldenham is increasingly a first choice for children of all abilities, including those at the top of the tree. Parents are attracted to the unpressured environment, community spirit and flexible boarding, along with the commitment to all-roundedness that beats the socks off other local schools. We found it a bit more liberal too. ‘It’s just a bit cool, Aldenham,’ as one parent put it. Requires high energy levels for the long days.

Learning support & SEN
Hitherto what Aldenham was famous for. In reality, the school can only cope with the mild to moderate dyslexia (most common), ADHD, autism etc that most mainstream schools can, although the 22 per cent on the SEN register (higher than national
Arts & extracurricular
Two enrichment afternoons a week, and most students belong to after-school clubs. The vast array of options include film club, art, fives, Warhammer, chess, archery, sailing and skiing. CCF (army and RAF, both joint with Queen’s School) popular, as
Sport
If music, drama and art shine, sport dazzles. It is integral to life at Aldenham and in a setting that needs to be seen to be believed – over 110 acres encompassing woodland, playing fields, two full-sized Astros, tennis courts, dance studio, weights
Boarders
Just under a third board (vast majority boys), usually staying two or three nights a week. Just the ticket for London families and those who commute, with others living very locally and simply boarding ‘for the fun of it’.
Everyone belongs to a
Ethos & heritage
Back in 1597, Queen Elizabeth I gave permission to local brewer, Richard Platt, to build and control a free grammar school for elementary children. Links with the Brewers’ Company remain strong, although the original Tudor buildings are long gone.
Pastoral care, inclusivity & discipline
Pastoral care has always been at the core – it wouldn’t be Aldenham without it. ‘There’s always someone to talk to,’ say students, though surprisingly few said they’d turn to the dedicated safeguarding staff members whose photos appear in every
Pupils & parents
Students are relaxed, sociable and unflashy. None of the smooth talking and practised polish we see at some independents. Upbeat too – among the happiest bunch we’ve met. ‘I went home from open day thinking, “Yup, I want one like that”,’ said a
Money matters
Scholarships at 11+ in music, drama, sport and academic and 13+ in all those plus art and DT. Worth up to 15 per cent fee remission. Means-tested bursaries available.
