What The Good Schools Guide says…

Senior School:

  • Parents believe the school gets the balance just right. ‘The grades are good, but you’re not made to feel awful if you’re not at the top of the league tables.’
  • A ‘rounded’ education given a firm emphasis, with a timetabled programme of ‘skills-based’ activities including everything from cooking to changing a tyre.
  • ‘People describe us as one of the best kept secrets in London,’ says the head, who clearly now intends the secret to leak out.

Prep School:

  • The curriculum, delivered by knowledgeable and experienced staff, runs roughly along National Curriculum lines, but one step ahead.
  • A positive, upbeat school with high academic standards and a warm family atmosphere, producing well-balanced, confident all-rounders.
  • Good range of clubs from reception, and working parents welcome the wrap-around care – as well as the overall family atmosphere.
