Lisbon · time the train
Lisbon’s internationals sit on the western line as often as in the city. Five climates share a capital and almost no Monday. Ask which paper the child will hold, and how much Portuguese the lanche still speaks.
Lisbon is not “the international school.” It is a Portuguese capital with a crowded coastal train, four English-medium campuses on the western line, a fifth in the city itself, plus colégios that stay families name in the second week.
The portraits we have are St. Julian’s School in Carcavelos, St. Dominic’s in São Domingos de Rana, CAISL in Linhó, Oeiras International School in a Barcarena valley, and United Lisbon on Avenida Marechal Gomes da Costa. Use them for euro tables and admissions rules. United Lisbon’s public policy prints application and enrolment euros, not a yearly tuition we will invent. St. Dominic’s public fees page prints dates and a 5% early-pay line, not a yearly table. This note is the city — and the line — between them. The Portugal country page is the wider map — São João de Brito, TASIS Portugal in Quinta da Beloura, CLIP in Porto — official doors we name without ranking.
St. Julian’s sits in Carcavelos, between the beach and the city. British memory, IGCSE, then IB, and a Portuguese bilingual path the portrait explains. If someone says “the old British school by the water,” this is often the gate they mean.
St. Dominic’s sits in São Domingos de Rana, a little further toward Cascais. Full IB continuum since 1997, Dominican Veritas in the copy, ISP in the footer. It is not St. Julian’s. Time Rua Maria Brown, not the beach.
CAISL sits in Linhó, Sintra. American on purpose. Portuguese is a core subject, not a hope. The commute is not Carcavelos and not the Baixa. Time Sintra traffic in November, not a June open day.
OIS sits in Barcarena, in Oeiras, on municipal land around a 17th-century quinta. Full IB continuum. From September 2026 the school prints three sites about seven minutes apart — PYP, Quinta, Horizon. It is a valley, not a beach. Ask which building this child would actually stand in.
Four of them share a line and almost no Monday. One is British in memory. One is a Dominican IB continuum in São Domingos de Rana. One is American on purpose. One is IB in a farm valley. United Lisbon is the city climate: English-medium in Lisbon proper, IPC then IMYC then the IB Diploma or the school’s own graduate award. Walk at least two, then a Portuguese courtyard. If the life is Lisbon proper, start in the city before you fall in love with a western commute.
If you might stay, an English-medium diploma is not automatically the kindest paper. A Jesuit colégio, a neighbourhood house with exames nacionais, a head who still knows the grandparents — those are official mornings. Families looking at St. Julian’s often also walk Colégio São João de Brito, then ask how much Portuguese the child will still have downstairs.
TASIS Portugal is a further Sintra conversation — Quinta da Beloura, not Linhó. American core, then IGCSE, then the IB Diploma. The admissions policy prints application euros. The public tuition page did not give us a yearly table we will invent. It is not a sixth card on the city hub. It is the next door families walk when Linhó is already in the week.
The language of the yard is the test that matters more than the flags. A child can thrive in English at 9 a.m. and still be lonely at 11 if the park is speaking Portuguese — or the other way around.
Porto keeps its own time. CLIP is the campus families name when the life is the north — British-and-Cambridge, not IB. The Porto field note is that Tuesday. Do not flatten Portugal into the Cascais train plus a holiday.
If you will leave, ask how universities outside Portugal read the diploma you are buying. If you will stay, ask how universities here read the English-medium paper, and whether extra Portuguese is required.
Housing and the gate have become the same conversation. That is not a reason to tour seven campuses. Name the paper, the language after lunch, and the train you can actually live with.
Ask which building this child stands in on a wet Tuesday — especially at OIS, where 2026 split the valley. Ask how much Portuguese a new twelve-year-old really meets in the first term. Ask what happens in the second week of October, when the novelty of the new country has worn off.
Walk the line on an ordinary Tuesday, not only in June light. The lanche is the honest tour.
The city hub is the short map. The five portraits are the long ones. American schools in Europe is the climate CAISL belongs to, if that is the leaving certificate you mean.
Friendly orientation, not formal admissions advice. Always confirm dates with the school.
The official site is caislisbon.org. The campus is in Linhó, in the municipality of Sintra, not in central Lisbon. English is the classroom language. Portuguese is a core subject. The 2026/27 fee schedule is printed in euros, quarterly or yearly.
Barcarena, OeirasA not-for-profit IB continuum on municipal land in Barcarena, not on the Carcavelos sand. From September 2026 the school prints three sites seven minutes apart. The fee table is public. Time the valley, not the postcard.
São Domingos de RanaA Cascais-line IB continuum, not St. Julian’s by the water and not United Lisbon in the city. The fees page prints term dates and a 5% early-pay discount. It does not print annual tuition as text. We will not invent the missing line.
CarcavelosThe process fees are public. The annual tuition sits in charts on the fees page. We will not guess the missing euros.
The letters on the leaver’s certificate matter. They are not the whole child. Here is how to tell them apart without a headache, and without pretending every door stays open.
16 minYou do not need a perfect algorithm. You need a few true things about your child, a boring list on the fridge, and the courage to ignore a beautiful campus that does not fit.
15 minTuition is the number on the homepage. The PDF is the number that arrives in March. Here is how to read the second one, without inventing a euro, a krona, or a deadline.
12 minSkip the question about last year’s average. Ask the ones that make a teacher’s face change. Then look at the corridor while they answer.
