An American international school outside Lisbon and the youngest in the TASIS family of schools: it has been running since 2020, while the family itself goes back to the school in Switzerland opened in 1956. It is held by the Swiss non-profit TASIS Foundation. The campus stands in Sintra, between Lisbon and Cascais, on Alameda do Linho, and keeps growing: several buildings, two libraries, laboratories, a theatre, sports fields, art studios, a dining hall with a cafe and a forest area for outdoor lessons. There are more than 950 pupils, from the pre-kindergarten groups to Grade 12, among them 61 nationalities and 57 languages spoken at home. Lessons are in English - the school names English as the medium of instruction outright and checks it with the WIDA test for those arriving from another school system; Portuguese is taught as a separate subject and there is also an after-school course for beginners. The programme is built from Core Knowledge, Singapore Math through Grade 8 and Amplify Science, Grades 9 and 10 take IGCSE subjects and Grades 11 and 12 the International Baccalaureate Diploma: the class of 2026 gave an average of 34.6 points with a 98 per cent pass rate. Every elementary classroom has two teachers, and the early learning centre has 21 educators for 134 children. The annual fee runs from 13007 euros in the pre-kindergarten group to 24308 in Grades 11 and 12, and already includes books, a lunch and two snacks, after-school activities, violins for the grades that need them and school trips; separately the school charges 750 euros a year for re-enrollment, 5000 euros once for campus enhancement and 100-150 euros for the application. There are more than fifty after-school activities - from surfing, judo and kendo to Model UN, forest school and the inventors' club, plus dance, music and language academies at an extra charge.

About the fees The annual fee is named by division and is paid in three instalments - 1 July, 1 December and 1 March: pre-kindergarten 13007, kindergarten and Grades 1-2 17290, Grades 3-5 19246, Grades 6-8 20028, Grades 9-10 23093, Grades 11-12 24308 euros. The fee includes books and instructional materials, a lunch and two snacks every day, after-school activities and sports, violins for the grades that need them, and school field trips. Transport and the external IGCSE and International Baccalaureate examination fees are paid separately. A third child in the family is given a 15 per cent discount, a fourth 25.
Admissions The school admits children of any nationality: its admissions policy says plainly that it does not discriminate in any way regarding admission, and among its pupils it names 61 nationalities and 57 languages spoken at home. Applications are considered throughout the year. Into the PK1 pre-kindergarten group it takes children who turn 3 before 1 September and are already toilet trained, and into kindergarten those who turn 5 before 1 September. Lessons are in English, so children coming from a different school system are checked with the WIDA English test, and in the elementary, middle and high school MAP tests in reading and mathematics are added. For the International Baccalaureate Diploma it takes those who have completed Grades 9 and 10 with at least six IGCSE subjects at grade C or above. Siblings of current pupils are given priority in the wait pool.
Stages and year groups Grades pre-kindergarten groups PK1 and PK2 (ages 3-5), kindergarten and Grades 1-5, Grades 6-8, Grades 9-12. The school is laid out in four divisions: an early learning centre for children from three to five, an elementary school from kindergarten to Grade 5, a middle school from Grade 6 to Grade 8 and a high school from Grade 9 to Grade 12. Grades 9 and 10 take Cambridge IGCSE subjects, Grades 11 and 12 the International Baccalaureate Diploma. The backbone of the programme is Core Knowledge, Singapore Math through Grade 8 and science by Amplify Science.

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: DP (ages 16-19). 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.

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 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.

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 is a candidate for accreditation by this organisation: the route has been started but not completed. Candidacy speaks of an application made and a file accepted for consideration, not of the outcome of an inspection, and the organisations themselves usually require schools to say that it does not guarantee accreditation. The candidacy is confirmed in the organisation's open directory.

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: IGCSE (ages 14-16). IGCSE means exams at around Year 10 or 11, the British counterpart of a lower secondary leaving certificate.

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 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.
