Our take

Independent girls senior school in Berkshire for ages 11–18. Selective entry, top-tier London fees.

Best for
Who thrives here
  • Families seeking a senior school for ages 11–18, with thinking already on 11+ or 13+ entry.
  • Parents who want a single-sex environment for their daughter.
  • Children who can demonstrate strong academics at entry assessment — this is a selective school.
  • Families comfortable with top-tier London independent fees in exchange for the level of provision.
Watch-outs
Know before applying
  • Fees sit at the top of the London market. Factor in extras (uniform, trips, lunches, music tuition) before committing.
  • 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.
  • Single-sex (girls). Comfortable for some children, less so for others — worth a visit on a normal teaching day rather than only an open-day showcase.
