How to Choose an International School in Lisbon (2026 Fees Included)

Choosing an international school in Lisbon as an expat parent comes down to four curriculum choices, two systems (public or private), and a fee sheet where the extras (enrolment, capital levy, bus, lunch, exams) can add thousands to the headline tuition. We've put the 2026/27 fees for the main schools in one table below. This is not a ranked list. The right answer depends on how long you are staying and where your child goes next.

The four curriculum choices

Lisbon has four main curriculum systems for expat families. Each one points your child toward a different university pathway, costs a different amount, and uses a different language of instruction. Pick the one that matches your length of stay and your child's likely next country, not the one with the prettiest brochure.

International Baccalaureate (IB). Taught in English. Covers ages 3 to 19 across PYP, MYP, and DP programmes, although most Lisbon IB schools start at PYP (age 3) and finish with the Diploma at 18. At the schools in the fees table below that teach IB all the way through, annual tuition runs from about EUR 11,800 to 26,700, plus enrolment and capital fees. The IB Diploma is recognised by leading universities worldwide. For families who do not yet know where they will end up, it is the most portable choice.

British Cambridge / IGCSE. Taught in English. Covers ages 3 to 18, with IGCSE around ages 14 to 16 and A-Levels at 16 to 18. Annual tuition runs from EUR 12,500 to 27,500 at the British schools in the fees table below. Strongest fit for families heading back to the UK, Ireland, or any Commonwealth country, although A-Levels are accepted by US universities too.

American curriculum. Taught in English. Covers Kindergarten through Grade 12 (ages 5 to 18). Tuition sits between about EUR 12,200 and 24,300 a year at the two American schools in the fees table below. Best fit if you want a US high-school diploma, AP coursework, and a clear path to American university applications.

Portuguese national curriculum. Taught in Portuguese. Covers ages 6 to 18 (mandatory schooling), with optional pre-school from age 3. Free in public schools. Private Portuguese schools set their own fees and are not in the fees table below, so ask each one for a written fee sheet. Right call if you are staying long-term, want your child fluent in Portuguese, and are comfortable with a slower English-language pathway.

Lisbon international school fees 2026: what expat families pay

For the 2026/27 school year, yearly tuition at the main international schools around Lisbon runs from €9,830 for the youngest children (PaRK's bilingual early years) to €27,500 for the last two years at King's College School Cascais. Most schools also charge a one-off enrolment or capital fee of €3,000 to €5,250 when your child joins, the school bus adds roughly €2,300 to €4,200 a year, and lunch is about €1,200 to €1,900 a year where it isn't already in the fee.

Every figure below comes from the school's own 2026/27 fee page or fee sheet. Schools update them every year, so use the table to compare and the school's own sheet before you sign.

St. Julian's School in Carcavelos (British and IB) also publishes its 2026/27 fees on its own fees page, so add it to your comparison from there.

Hidden costs to budget for

• Capital or building levy. Ask if there is one and whether it is ever refunded. St. Dominic's (€5,250), OIS (€5,000) and TASIS (€5,000) charge it once, while CAISL charges a €1,953 building fee every year for a student's first five years from Grade 1.
• Yearly re-enrolment fee. Several schools charge €600 to €1,200 a year to hold your child's place for the next year (King's, TASIS, PaRK, United Lisbon, the Sharing School). Ask whether it comes on top of tuition.
• Exam fees. Ask what the IGCSE and IB years cost. King's and PaRK list €165 per IGCSE subject and €920 for the IB Diploma exams, and OIS bills €900 in both Year 11 and Year 13.
• Trips. Ask which trips are in the fee. Day trips usually are, but CAISL, King's, St. Dominic's and United Lisbon charge separately for overnight, residential or international trips.
• Devices. Ask what your child needs to bring. King's and PaRK offer an iPad package for €1,131 or rent one for €105 a term, and United Lisbon asks every student from Grade 6 to bring a personal laptop.
• Uniforms. Ask for the full uniform list with prices. King's leaves uniforms out of tuition, and United Lisbon prices its PE kit item by item (about €7 to €40 a piece).
• English support. If your child is still learning English, ask what extra lessons cost. United Lisbon charges €750 to €1,200 a semester for its higher support levels, King's €35 an hour.
• Sibling discounts. Ask how they work. Most of these schools start at the third child (10% to 15% off), while St. Dominic's and OIS also take 5% off for a second child.

How the Portuguese public system works for foreign families

Most expat parents skip the public route without checking it. Worth reconsidering, especially for younger children who pick up Portuguese fast.

Every child residing in Portugal has the right to free public education. The Portuguese Constitution sets out a right to universal basic education in Article 74, and Article 15 extends the same fundamental rights to non-Portuguese residents. Enrolment runs through the local Agrupamento de Escolas, the school cluster covering your home address. You cannot pick a school across town; the system is geographic.

To enrol, you need: a residency document or proof of address (atestado de residência), your child's passport, an up-to-date vaccination record (boletim de vacinas), and prior school records translated into Portuguese. Application windows for the September start typically open in April and close in mid-May, but exact dates shift each year. Check the Portal das Matrículas operated by the Direção-Geral da Educação for the current calendar before you plan around it.

For children whose first language is not Portuguese, public schools run a programme called PLNM (Português Língua Não Materna). It provides extra Portuguese tuition during school hours, levelled by the child's current ability. Quality varies by school, so ask the Agrupamento how PLNM is delivered before you commit.

For families navigating the Agrupamento paperwork from abroad or short on Portuguese, our directories of sworn document translators in Lisbon handle school-record translations, and vetted gestors in Lisbon can submit the enrolment forms in person if you cannot attend.

The public system is the right call when: you plan to stay in Portugal more than three years, your child is under 10 (faster language acquisition), and you want them genuinely integrated rather than parked in an English-language bubble. It is the wrong call when your timeline is shorter than 18 months or your child is already in the middle of a non-Portuguese curriculum that they need to finish.

A vetting checklist before you sign anything

Two things expat parents get burned by in Lisbon: hidden fees that triple the advertised tuition, and schools whose accreditation does not match the marketing. Run every shortlisted school through this checklist.

Accreditation. Verify IB World School status directly at ibo.org. Verify Cambridge accreditation at cambridgeinternational.org. Every private school operating in Portugal must also be authorised by the Direção-Geral da Educação (DGE); ask for the school's autorização de funcionamento number and check it on dge.mec.pt. If a school cannot produce these on request, walk away.

The full cost sheet. Tuition is the headline number, not the real number. Ask, in writing, for: enrolment fee (one-off or recurring), capital or building levy, lunch and snacks, uniform, books and materials, transport, after-school programmes, exam registration fees (IGCSE, IB, AP), and any sibling discount terms. Total it. Compare totals across schools, not tuition figures.

Waiting lists. Top international schools in Lisbon run waiting lists of 12 to 24 months for popular entry points. Ask the admissions office, in writing: what is my child's current waitlist position and how many places typically open at this entry level each year. A vague answer means you are not actually in.

Community references. Talk to at least three current parents, not just the ones the school introduces you to. Ask about administrative responsiveness, how the school handles a complaint, and whether the costs they were quoted at enrolment matched the costs they actually paid.

Using Locallista reviews to vet a school

Marketing pages tell you what schools want you to know. Parent reviews tell you what they wish they had known. Locallista reviews are phone-verified before we publish them. The same complaints keep appearing across listings when they are real (slow admin, surprise fees, weak SEN support) instead of getting buried under polished testimonials.

When you read a Locallista listing for a school, focus on: reviews from the last two years (older ones may pre-date a leadership change), reviewers whose family situation matches yours (age of child, length of stay), and specific complaints rather than star ratings. A school with mostly fives but three detailed twos about the same issue is telling you something a five-star average will not.

For families bridging a transition between systems, our verified directories of Portuguese teachers in Lisbon help with after-school language reinforcement, and our English teachers directory covers families easing children into the Portuguese public system without losing English literacy.
