Why ISJ
The School Where Every Child Is Known
When you visit ISJ, you notice it immediately. The Head greets your child by name. The teacher knows who they sat with at lunch yesterday. The PE coach knows they're nervous about swimming but brilliant at football.
This isn't an accident. It's the product of deliberate choices: the number of children ISJ teaches, the teachers the school recruits, and the kind of institution it set out to build.
Curriculum
The English National Curriculum, All the Way Through
ISJ follows the same curriculum taught in the best independent schools in England, from the Early Years Foundation Stage through GCSEs and A-Levels. The real thing, delivered in full.
Your child can join at age 2 and leave at 18 with qualifications recognised by every university in the world. One coherent journey. In independent standardised assessments, ISJ pupils score 17 points above the international average in English and 18 points above in Maths, placing the school in the top 10% of international schools globally.
The Teachers
100% UK-Qualified
Every teacher at ISJ is recruited from the UK's leading independent schools. They hold British teaching qualifications, they know the curriculum inside out, and they chose to teach at ISJ because they believe in what the school is building.
This matters because the quality of teaching is the single biggest factor in your child's education. The person standing in front of the class. Meet the Head.
"A personalised teaching approach and strong support for each child."

Personal Attention
Personal by Design
Your child's teacher can spot when they're struggling before they ask for help. The Head knows every family. Safeguarding is practised, every day, by people who know your child. That's what personal attention actually means.
15 children per class in Early Years. 20 from Year 1 onwards. A staff-to-pupil ratio of 1:9 across the school. See it for yourself.

The Foundation
Part of The Schools Trust
ISJ was founded by The Schools Trust, a UK-registered charity that has established 16 schools across 11 countries since 2004. Every one of those schools has been rated "Excellent" in every category of its UK government-accredited inspection.
The Trust's schools are ranked 1st and 2nd across a network of 200+ British schools internationally for A-Level and GCSE results. ISJ inherits that track record: the same governance, the same standards, the same expectation of excellence.
