Montgomery International School was founded in 2007 by David Gerone as a school for children who did not fit the conventional system; in 2015 it adopted the IB and within eight years was authorised for the PYP, MYP and DP. Since September 2023 it has been part of the French Ermitage Education Group. It has almost 200 students from more than 50 nationalities, most of whom come from abroad. The school is in central Brussels by Montgomery square, close to the EU institutions and NATO, in a mansion built in 1907. Its distinctive feature is the choice of two tracks from PYP 2: fully English or Advanced Bilingual English-French, leading to the IB Advanced Bilingual Diploma. Admissions are open, without academic selection, yet graduates have passed the IB Diploma at 100% for seven consecutive years.

Admissions "Montgomery International School is inclusive and welcomes students from all backgrounds, nationalities and cultures"; the school has an open admissions policy. In the PYP "we accept all students from the age of 5.5 (by September) to the age of 11", with the last two report cards. For the MYP report cards are reviewed and placement tests in Math, English and/or French may be required; for the DP two years of report cards and placement tests in mathematics and languages are required, and transfer into DP 2 is agreed with the previous school. Students can join with little or no English up until MYP 5 (Grade 10); English proficiency is required only for Grades 9-12. There is no application deadline and students are accepted during the year if places are left; the steps are an enquiry, a visit or video call, an application on the platform, report cards, an offer and enrolment.
Stages and year groups Grades PYP 1 - DP 2 (Grades 1-12). IB Primary Years Programme: PYP 1-5 (Grades 1-5, from age 5.5 to 11). IB Middle Years Programme: MYP 1-5 (Grades 6-10, ages 11-16).

In the DP the bilingual track leads to the Advanced Bilingual Diploma: French Language and Literature, English Language and Literature and History in French.

IBInternational Baccalaureate
A Swiss non-profit, working since 1968. Its programmes are among the most widely recognised school programmes in the world. Authorisation is granted stage by stage, so a school with the final stage does not necessarily run the younger ones; which stages this school holds is set out in the line below.
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: PYP (ages 3-12), MYP (ages 11-16), DP (ages 16-19). PYP is the primary stage, ages 3 to 12. It is not a set of subjects but a frame for the whole school: learning is built around lines of inquiry, and there are no exams at the end. MYP is the middle stage, ages 11 to 16. There are no exams here either; at the end an optional electronic assessment of pupils' work is possible. DP is the final stage, ages 16 to 19: six subjects plus a compulsory core of theory of knowledge, an extended essay and CAS. The diploma is accepted by universities all over the world, and in a number of countries it counts for admission on the same footing as the local leaving certificate.

A French education group; its page is on the site of its flagship school, ermitage.fr. The group describes itself as a family-founded institution set up in 1941 that has grown into an international group in France and Belgium: nearly 2000 day and boarding students aged 3 to 18 on five campuses, with IB, Cambridge IGCSE and French curriculum programmes. The group's page names five schools: Ermitage International School Paris in Maisons-Laffitte (founded in 1941), Sainte Victoire International School in Aix-en-Provence (2011), Montgomery International School in Brussels (2007), International School 33 in Bordeaux (2014) and the new Ermitage International School Bordeaux. The group's president is Jim Doherty. Montgomery's own site says the school joined the group in September 2023 and names three schools in the group rather than five; we quote both figures.
What this means for this school. The network owns or operates the school. Its accreditation and programme authorisation the school obtains separately, in its own name.

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.
Criteria breakdown criterion weight in brackets

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 8 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.
