With just 188 pupils on roll, it has the intimate scale that allows staff to know each child well.

Teaching & academics
The ISI's 'good' overall rating sits alongside an 'excellent' grade for personal development, pointing to a school that values character as much as classroom results. Academic scholarships are available for able pupils, and the school prepares children for 11+ entry as well as the wider 13+ transition that defines a prep school. The relatively high proportion of pupils on SEN support indicates teaching geared towards individual progress.

Beyond the classroom
A music scholarship signals that musical talent is recognised and encouraged. As a boarding school, daily life extends well beyond lessons, giving pupils scope to develop interests in the hours outside the timetable.

Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A small, nurturing prep with boarding on offer and a particular strength in pastoral care. Worth a look for families wanting close attention and an all-round upbringing rather than a large institution.
That’s where Passmate comes in. Tutoring is the most effective thing in a child’s preparation - a well-tutored child can outperform the vast majority of their peers. Passmate works alongside your tutor, not instead of them: it learns how your child thinks, finds the gaps, and shows the tutor exactly where to spend each session - so the limited time you have lands on what actually decides a place.
Works alongside your child’s tutor - not instead of them.
