Our take

Independent co-ed senior school in Hertfordshire for ages 11–18. Selective entry.

Best for
Who thrives here
  • Families seeking a senior school for ages 11–18, with thinking already on 11+ or 13+ entry.
  • Families who prefer a co-educational setting over single-sex.
  • Children who can demonstrate strong academics at entry assessment — this is a selective school.
Watch-outs
Know before applying
  • Selective entry — assume some form of assessment at the relevant entry point. Plan tutoring or familiarisation early if needed.
  • SEND provision isn't documented in our profile. If your child has an EHCP or specific learning needs, ask admissions about case-by-case capacity before applying.
