International British Online School
School summary
A relatively new arrival on the independent scene, the International British Online School was founded in 2019 and delivers a British curriculum to a small community of around 55 pupils. With an Anglican character and a mixed intake, it is notable for its weighting towards older pupils: 35 of its students are in the sixth form, suggesting much of its work centres on GCSE and A-level preparation. The pupil-to-teacher ratio of about 15 reflects the scale of a genuinely small school. Inspection is carried out by the ISI, the body that oversees independent schools.

Teaching & academics
Results are solid at both key stages. At GCSE, 67% of grades fall in the 9-7 range, while at A-level 54% reach A*-A and 82% reach A*-B, indicating that strong performance extends across the upper grades rather than clustering only at the very top. The school offers GCSE and A-level qualifications, and its small size points to a closely supported teaching environment.

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.
