What The Good Schools Guide says…

  • 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.
