Schooling in Lisbon: public, private, and international

Bring a school-age kid to Lisbon and you're choosing between three genuinely different systems: free public school taught in Portuguese, a private Portuguese-curriculum colégio, or one of the international schools running a British, American, French, German, or IB programme. The right call depends less on budget than on how long you plan to stay and whether your child will sit Portuguese exams down the line.

The three paths

Public school (escola pública) is free and zoned: your home address is mapped to a local agrupamento de escolas (school cluster), and that's the school your child is assigned by default. It's genuinely good academically and, for younger kids especially, the fastest way into the language and into local friend groups. The catch is the language itself — instruction is entirely in Portuguese, though schools run PLNM (Português Língua Não Materna) support classes for non-native speakers and are required to provide it.

Private, Portuguese-curriculum colégios sit in between: still teaching the national curriculum and sitting the same exams as public schools, but smaller classes, often bilingual tracks, and a few thousand euros a year rather than free. Families who plan to stay long-term and want their kids inside the Portuguese system, just with more attention, land here.

International schools teach a foreign curriculum (British, American, French, German) or the IB, almost entirely in that language. This is the default choice for families who expect to move again, want a curriculum that transfers internationally, or want their child in English (or French, or German) full stop. It's also by far the most expensive option, and the best-known schools run real waitlists.

How public school assignment actually works

Enrolment for public school runs through the Portal das Matrículas, where you log in as Encarregado de Educação (parent/guardian) using a Cartão de Cidadão, Chave Móvel Digital, or your Finanças credentials. Your address determines your assigned agrupamento, but you're not locked into it: if another school has open places, you can list it as a preference. You'll need the child's passport, a vaccination record, proof of address, your NIF, and academic records from any previous school (translated, and apostilled if from outside the EU).

Arriving mid-year? You don't have to wait for the next admissions window — register directly at the local agrupamento's office and they'll place your child as soon as there's a spot.

Timing: start earlier than feels necessary

The Portuguese school year runs September to June. Public school registration season is roughly January to April for the following September, the exact dates are published by the Direção-Geral dos Estabelecimentos Escolares each year. Private colégios run their own admissions on a similar timeline.

International schools are the one place where "we'll sort it when we land" genuinely backfires. The well-known names in Lisbon, Cascais, and Sintra fill popular grades a year or more ahead, and some operate formal waitlists for the most requested year groups. If an international school is the plan, start applications as soon as you know you're moving, not after you've found a flat.

What it actually costs

Public school is free. Private Portuguese-curriculum colégios in Lisbon typically run a few thousand euros a year. International schools are the biggest range: roughly €11,000 to €23,000 a year depending on the school and your child's grade, before one-time registration or "building" fees that some schools charge in the early years. The school-by-school comparison below has real, currently published numbers (and says "fees on request" rather than guessing where a school doesn't publish a clean table).

One detail that surprises a lot of newcomers: it's the same SNS-style trade-off as healthcare. Public is free and good but means full Portuguese immersion; private buys you curriculum choice and (usually) English, in exchange for a real bill. Few families regret visiting at least one public school before ruling it out.
