Admissions The school accepts children from 18 months to Year 13 and may place an applicant in the year group that matches their assessment. Families first contact the admissions team and meet online or in person, then visit the school. From Year 3 children take an assessment and an interview with the Head of Primary or Secondary; a trial day is arranged where possible. The family then completes the mandatory documents; if no places are available, the child joins the waiting list. Entry to Year 12 requires five IGCSEs at A* to C (9-4), including English Language and Mathematics. The school calls itself truly international, with students of 28 nationalities, and has a dedicated EAL team for children with limited English. For Years 8 and 11 the school has offered three scholarships based on past achievement, an interview and an assessment.

CambridgeCambridge International Education
Part of the University of Cambridge. It allows a school to teach the Cambridge programmes and to enter pupils for the exams. There are four stages and they are authorised separately: primary, lower secondary, IGCSE and A Level. If the stages are known they are named in the line below; if that line is missing, the school does not publish them, and the Cambridge registry does not show stages either - it gives only the name of the centre, the country and whether private candidates are accepted. Cambridge calls what it does registration rather than accreditation, and the network holds about ten thousand schools.
What the badge means for this school. The school is allowed to run this programme and to award its certificate. This is a confirmation of the programme, not a judgement on the school as a whole. The entry stands in the organisation's public register - anyone can check it. At this school: Lower Secondary (ages 11-14), IGCSE (ages 14-16), A-Level (ages 16-18). Lower Secondary is the middle stage, ages 11 to 14, with the same optional Checkpoint test at the end. IGCSE means exams at around Year 10 or 11, the British counterpart of a lower secondary leaving certificate. A-Level is the senior years, and their results are what British and many other universities admit on.

A scheme of the UK Department for Education: a school abroad is inspected against the standards for independent schools in England, including safeguarding and the standards for boarding. The inspections are done by independent inspectorates approved by the department, and the inspectorates themselves are monitored annually by Ofsted. The reports are published in full on the government website.
What the badge means for this school. The school has been through this organisation's accreditation. It was judged as a whole: governance, safeguarding, staff, premises, teaching. The entry stands in the organisation's public register - anyone can check it.

An association of British schools abroad with a quality inspection of its own. It has nine membership categories, and the word "accredited" appears in seven of them, although COBIS does its own inspection in one: in the rest it recognises an accreditation granted by somebody else.
What the badge means for this school. The school belongs to this organisation but has not been through its accreditation. The difference matters: membership is usually paid for and has no external inspection behind it. The entry is confirmed in the organisation's open directory.

Reviews
No reviews yet. The community rating counts towards the score once a school has five verified reviews - until then we do not show a zero, so as not to mislead.

A low score here means the school does not write about this, not that the school does not have it: a school with good security and a sparse site will score low. A school can fill in its profile, and the score will be counted again.
The score is counted from 7 of the 9 criteria.Only those with checkable data count: programmes and accreditations from official registers, the fee from a published price list. Where it says "scored on the median", the school has no data and the middle of the list is put in its place, so that a gap gives no advantage. Admissions, teaching staff and reviews come in as their data arrives.
