An international school in Lisbon, at Avenida Marechal Gomes da Costa 9, which carries a child from the age of three to eighteen and keeps a boarding house. It teaches in English: the school calls its teaching an international education in English and sets out the language requirement by grade - no threshold up to Grade 2, A2+ in Grades 2 and 3, B1 in Grades 4 to 7, B2 in Grades 8 and 9, C1 in Grades 10 and 11 and C2 in Grade 12. The curricula follow one another: the International Early Years Curriculum, then the International Primary Curriculum, then the International Middle Years Curriculum and the International Baccalaureate Diploma at the end. The school names its accreditations itself: NEASC, the International Baccalaureate and the Council of International Schools. Among its pupils there are more than fifty nationalities, and the school keeps admission open: its policy calls its admissions open and inclusive and expressly invites applications from candidates of the most diverse backgrounds possible. Applications are accepted throughout the year subject to availability, younger applicants are seen in an informal interview and older ones take an online English test and a cognitive and abilities test; enrolment must be completed within ten working days of an offer. The school publishes its fees as a separate schedule and revises them every year: in the last readable schedule, for the 2022-2023 school year, the annual fee ran from 9947 euros in the pre-school groups to 20909 in Grades 11 and 12, the application fee was 240 euros, the enrolment fee 2000 euros, catering for the younger grades 110 to 156 euros a month and language support 1200 euros a semester.

About the fees The school issues its fee schedule as a separate document and updates it every year; for the current school year it is not served from the fees page, and the school's last readable schedule is the one for the 2022-2023 school year. In it the annual fee is named by grade: Pre-K3 and Pre-K4 9947 euros, kindergarten 10759, Grades 1 and 2 11774, Grades 3 to 5 12789, Grades 6 to 8 14616, Grade 9 18879, Grade 10 19894, Grades 11 and 12 20909. Catering for the pre-school groups and Grades 1 to 5 runs from 110 to 156 euros a month by stage, transport is charged by distance, and the language programme for those whose English falls short is 1200 euros a semester. Payment of the year in advance by 1 June earned a 2 per cent discount, a third child in the family 15 per cent and a fourth and beyond 25. The school calls a published schedule a binding part of the contract and warns that the amounts are revised for each school year, so the 2022-2023 figures are the last the school shows in words rather than the current ones.
Admissions The school keeps admission open and says so plainly: its admissions policy calls its policy open and inclusive, promises equitable treatment for all and expressly invites applications from candidates of the most diverse backgrounds possible; among its pupils the school names more than fifty nationalities. It takes children from the age of three, from the Pre-K3 group, up to Grade 12, and accepts applications throughout the year subject to availability. In Pre-K3 a child must already be out of nappies and reasonably able to feed and dress themselves. The English requirement is set out by grade: up to Grade 2 there is no language threshold, in Grades 2 and 3 level A2+ is needed, in Grades 4 to 7 B1, in Grades 8 and 9 B2, in Grades 10 and 11 C1 and in Grade 12 C2. Younger applicants are seen in an informal interview, older ones take an online English test and a cognitive and abilities test. Where candidates are equal, priority goes to returning pupils and to siblings of current and former pupils, and a candidate's previous behaviour and effort are taken into account. Enrolment must be completed within ten working days of an offer.
Stages and year groups Grades Pre-K3 and Pre-K4 (ages 3-5), kindergarten, Grades 1-12. There are four stages plus the diploma: early childhood from the age of three, the primary years, the middle school and the high school up to Grade 12, in all from three to eighteen. The curricula are international and follow one another: the International Early Years Curriculum, the International Primary Curriculum, the International Middle Years Curriculum and the International Baccalaureate Diploma at the end. The school also keeps a boarding house.

Accreditations and programmes verified against official registries
NEASC · accreditationIB · authorised programmeDukes · school is part of the networkThe school names the IB Diploma as the programme of its senior stage and says its first graduating class will take it in 2028. The school is not in the official IB registry: the Portuguese list was swept in full on 27.09.2026 and agreed with the registry's own counter. The record therefore stands on the school's own word and does not count towards the score.

NEASCNew England Association of Schools and Colleges
An American accreditation working since 1885. For international schools it uses an approach where the visitors look first at live lessons rather than at folders of paperwork: the team works in the school for about a week. It is the only one here whose public directory honestly separates accredited schools from candidates.
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.
Register to check for yourself, and the full guide →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 this status would mean. 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 school is not in the organisation's register: the status comes from the school's own words. Which stage this school is authorised for - PYP, MYP, DP or CP - is not stated here.
Register to check for yourself, and the full guide →IPC
International Primary Curriculum: a British primary school programme for children aged 5 to 11. It teaches through themes that draw subjects together rather than through separate subjects; it is published by the International Curriculum Association, formerly Fieldwork Education.
What this means for this school. This is a programme for the primary stage, not an accreditation of the school: the organisation sells it to schools and trains their teachers, but it does not check the quality of teaching at a particular school and keeps no public register of the schools working to it. There is no outside register to check it against, so the entry comes from the school's own words or from the record of its accrediting organisation. The programme has no leaving certificate: at the end of primary school a child moves on to the middle stage, and it is that stage which decides what they finish with.
IMYC
International Middle Years Curriculum: the continuation of IPC for the middle school, ages 11 to 14. The same organisation and the same thematic frame, only for teenagers.
What this means for this school. As with IPC, this is a programme for one stage rather than an accreditation of the school, and the organisation keeps no public register of the schools working to it. The entry comes from the school's own words or from the record of its accrediting organisation. The programme has no leaving certificate of its own: after it the school takes a pupil on to a final stage - IGCSE, A-Level, IB or a national programme - and that is what to look at.
Dukesschool network
A British group, founded in 2015 by Aatif Hassan; the legal entity in the footer of the site is Dukes Education Group Ltd. It calls itself a family of nurseries, schools and colleges in the UK and Europe, with one school in Canada in a section of its own. The total number of schools, pupils and countries is not named on the site. The numbers for Portugal diverge: the "Portugal" section lists six schools, while the group's own news item about the UK-Portugal Business Awards says four. Of the schools it is said that they join the family; whether the group owns them, manages them under contract or gives its methodology under licence is not said.
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.
Exams and destinations from the school's official website
The school publishes nothing about where its leavers go: no share going on to university, no exam results, no list of universities.
Facilities
The school does not describe its premises on its website.
Teaching staff
The school publishes neither the number of its teachers nor their qualifications.
Safety and wellbeing from the school's official website
The school says nothing on its website about security, medical care or pupil support.
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.
