St. John's International School was founded in 1964 by the FCJ, a Catholic order of nuns; since 2016 it has been part of the Inspired education group. The campus is in a quiet area of Waterloo, 15 minutes south of Brussels; the community counts more than 65 nationalities. The school offers the full IB continuum, PYP, MYP and Diploma, with over 40 years of IB experience, as well as AP courses. "English is the primary language of instruction throughout the school"; Early Years and Primary run an English-French dual language programme, and Grades 9-10 have a Mother Tongue Programme. Children are accepted into the creche from 12 months. A distinctive feature is the school's own boarding house, Shannon House, for students from age 11, with full, weekly and flexible boarding. The arts are a strength: a 400-seat professional theatre and annual musicals with more than 100 participants.

About the fees Annual tuition for the 2026-2027 school year: EY1 and EY2 14750 euros, EY3 and EY4 20300, EY5 28900, Grade 1 37800, Grades 2-5 38550, Grade 6 41500, Grades 7-8 43900, Grade 9 44700, Grades 10-12 46500 euros. Boarding is charged on top of tuition.
Admissions "Admission to St. John's is open year-round to students of all nationalities, faiths, and backgrounds." After the enquiry there is an interview, which can be held remotely; a visit is encouraged but not mandatory. The principal decides on acceptance and placement based on the applicant's potential to benefit from the school's programmes. English is not required, but "Grade 8 is the last year to which an absolute beginner English Learner is admitted"; English as an Additional Language support is provided. The school encourages all students to attempt the IB Diploma, and DP and AP courses are chosen with the coordinator. Boarders are accepted from Grade 6, each application assessed individually; for holders of an EU or EEA passport the process does not differ much from the normal application.
Stages and year groups Grades EY1 - Grade 12. Early Years (ages 1-6): EY1 and EY2 are the Day Care and Timbertops creche, EY3 and EY4 Pre-K, EY5 Kindergarten; the programme follows the IB PYP framework and the Reggio Emilia approach, with activities in English and French. Primary School (ages 6-11, Grades 1-5) follows the IB PYP, Middle School (ages 11-14) and High School (ages 14-18) the IB MYP, and Grades 11-12 the IB Diploma. Instead of the full diploma students may take individual DP courses and Advanced Placement courses (Calculus, Economics, Statistics, Physics, French, German, Spanish); graduates also receive the St. John's High School Diploma. Early Years and Primary run an English-French Dual Language Programme, and around half of graduates earn the IB Bilingual Diploma. Boarding starts in Grade 6.

What stands behind each entry

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.

CISCouncil of International Schools

It accredits international schools and is a paying association at the same time. It examines governance and ownership, the curriculum, teaching, student wellbeing, staff and premises; a team of volunteers from other CIS accredited schools visits the school. Membership and accreditation are different things here, and schools confuse them more often than anything else.

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.

MSAMiddle States Association of Colleges and Schools

One of the oldest American accreditations, working since 1887 in more than a hundred countries and linked to the Office of Overseas Schools of the US State Department. It judges the school as an institution across twelve areas, including finances, governance, premises and student support.

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.

College BoardCollege Board, the AP programme

An American organisation that allows a school to put the letters AP on a pupil's transcript. The permission is granted course by course and tied to a particular teacher, it has to be renewed every year, and College Board reads the course syllabus before granting it.

What the badge means for this school. The school is allowed to run advanced AP courses - not the school as a whole, but one by one: by subject and by teacher. Governance, safeguarding and the primary years are not part of that check. Which subjects are actually approved is visible in the ledger. The entry stands in the organisation's public register - anyone can check it. Authorisation here runs a year at a time: the register lists the school for the 2025-2026 school year.

AP

Advanced Placement: American advanced courses for the senior years. The exam for a course is set and marked by the College Board, not by the school. A good result is counted by American universities as a first-year course already passed, which saves a student time and money.

What this means for this school. A school does not get to call a course AP automatically: the College Board reads the course syllabus and approves it separately for every subject and every teacher, and the permission has to be renewed each year. Every approved school in the world is listed in the open AP Course Ledger, and this school's entry there stands as a line in the accreditation block above. How many courses a school is approved for, and in which subjects, the ledger does not show in its general listing. AP has no leaving certificate of its own: it sits on top of the school's main programme rather than being a separate system.

American programme

The American school programme, with the High School Diploma at the end. It usually comes together with AP courses, which the College Board stands behind, and with an American accreditation - MSA, NEASC or Cognia.

What this means for this school. The diploma is written out by the school itself: the American programme has no common leaving exam, and the content of the senior years is set by the school. Outside checking therefore rests on two things here - the accreditation of the school, and the AP exams if the school runs them.

Inspiredschool network

Inspired Education Group is a private school group founded in 2013. The group gives different figures on its own pages - 125 schools on some, "more than 100" on others - and we quote both: choosing for a group which of its own numbers is correct is not something we do. Its schools are in Europe, Latin America, Africa, the Middle East and Southeast Asia, and some of them keep their own historic names, such as King's College in Madrid and Riga. The group's site is inspirededu.com.

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.

"Scored on disclosed data" stands where we count only what the school has written about itself on its own site: exams and destinations, safety and wellbeing, teaching staff, facilities, clubs and activities. 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. The full methodology →
