International School of London
School summary
Founded in 1972, the International School of London takes the International Baccalaureate as its sole curriculum, a choice that shapes its outlook from the first year of senior school through to the sixth form. It is a small, mixed independent school of around 395 pupils, with a sixth form of about 65, in Hounslow, west London. The intimate scale lends itself to close attention, and the IB framework suits families who value a globally minded, inquiry-led education over the traditional GCSE and A-level route. A notably high proportion of pupils, close to a quarter, receive SEN support.
Where every mark matters.
Places are limited and demand is high, so exam performance is what sets candidates apart. Passmate turns the months ahead into ten focused minutes a day on the exact topics this school tests.

Teaching & academics
The school offers the International Baccalaureate throughout, an approach that emphasises breadth, critical thinking and international perspectives rather than early specialisation. With roughly 22.7 per cent of pupils on SEN support, learning differences are clearly a familiar part of daily life here. It is inspected by the ISI rather than Ofsted.

Mobile phone policy
Students are allowed to bring mobile phones to and from school to ensure their personal safety. Upon arrival, phones should be switched off and placed in lockers. Students must not use their phone or any related device during the school day, except under the direction of a teacher. Mobile phones are also not permitted at after school extracurricular clubs and can only be switched on upon leaving the school site. Any student found using, or known to have used, their phone at school will have it confiscated and returned at the end of the day via the pastoral team, with parents informed.

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.
