School summary

Set in Glastonbury, Somerset, Millfield Prep is an independent boarding and day school for boys and girls from the early years through to age 13. Founded in 1945, it now educates around 471 pupils, with a pupil-to-teacher ratio of about 14 to 1 that reflects its position as a relatively small school. The Independent Schools Inspectorate awarded it an "excellent" rating, including for personal development, and found all compliance standards met. Roughly one in five pupils receives some form of SEN support, suggesting a setting accustomed to meeting a range of learning needs.

Teaching & academics

An ISI judgement of "excellent" places teaching and learning here among the strongest the inspectorate recognises. The manageable teaching ratio of around 14 pupils per teacher gives staff scope to know children individually across the wide 2-13 age span. The notable level of SEN support indicates a school willing to adapt for pupils who learn differently.

Beyond the classroom

Sport features prominently in the school's wider programme. As a boarding school, daily life extends well beyond lessons, with boarders able to use personal devices to keep in touch with families privately.

Watch Passmate decide how to teach.

Answer as a child would. Left: what they see. Right: what it learns about them.

A small, well-regarded prep school for families wanting day or boarding provision through to 13, backed by a top ISI rating. Fees range widely, so prospective parents should weigh day costs against the boarding option carefully.

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.
