Portsmouth High Prep School
Founded in 1927, Portsmouth High Prep School is a small independent girls' school in Southsea, with around 127 pupils on roll. Its modest size translates into a pupil-to-teacher ratio of roughly 15 to one, allowing teachers to know each girl well. As a non-denominational school, it welcomes families of all faiths and none. Inspected by the ISI rather than Ofsted, it sits firmly within the independent sector, with day fees ranging from £10,755 to £14,178 a year. Under Headmaster Mr Paul Marshallsay, it offers a self-contained primary stage for girls before the senior years.

Teaching & academics
Teaching is delivered to a small community of girls, and the pupil-to-teacher ratio of about 15 supports close attention to individual progress. With fewer than 130 pupils across the prep stage, classes are likely to be intimate, giving staff room to tailor support and stretch.

Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A small, established girls' prep in Southsea where every pupil is a known quantity rather than a number. Best suited to families seeking an intimate, single-sex primary environment in the independent sector.
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.
