International vs National Schools: Expat Guide to Portugal

Moving to a new country with children is one of the most courageous decisions a family can make. Among the long list of logistical concerns — housing, paperwork, health insurance — choosing a school almost always rises to the top. For expat families in Portugal, the fundamental question is unavoidable: international school or national school?

There is no universal answer. The best choice depends on your children's ages, the expected length of your stay, your family budget and your long-term educational goals. This guide was written to help you navigate that decision with clarity and confidence.

The Portuguese School System: An Overview

The Portuguese public education system is organised into three main stages:

Pre-school (ages 3 to 5): Optional, but widely available and free in the public system
Basic Education (ages 6 to 14): Compulsory, divided into the 1st cycle (4 years), 2nd cycle (2 years) and 3rd cycle (3 years)
Secondary Education (ages 15 to 17): Compulsory since 2009, lasting 3 years

Portuguese public schools are free, inclusive and follow the national curriculum set by the Ministry of Education. In recent years, Portugal has invested significantly in modernising its education system, with rising performance in international rankings such as PISA.

The language of instruction is Portuguese, which can present an initial challenge for newly arrived families. However, many public schools now offer language integration support programmes to help non-native speakers settle in.

International School Systems in Portugal

International Baccalaureate (IB)

The IB is globally recognised and values critical thinking, international-mindedness and interdisciplinary learning. In Portugal, several schools offer the full programme — from the Primary Years Programme (PYP) through to the Diploma Programme (DP) for senior students. The IB Diploma is accepted by universities worldwide.

British Curriculum

British schools follow the National Curriculum of England, with GCSE and A-Level assessment milestones. They are a popular choice among British and Commonwealth families, but also among Portuguese families seeking an English-language education. The system is structured and exam-focused.

American Curriculum

American schools follow the US system, with the Elementary, Middle and High School structure. Students prepare for the SAT and can earn an American High School Diploma. It is an ideal option for families planning to return to the United States or apply to American universities.

French Curriculum

The network of French lycées in Portugal, connected to AEFE (the Agency for French Education Abroad), follows the French national curriculum. The Lycée Français Charles Lepierre in Lisbon is the primary reference. The French Baccalauréat is widely recognised internationally.

Key Differences

Language of Instruction

National schools: Portuguese (with compulsory English from the 1st cycle onwards)
International schools: English, French or another language, depending on the curriculum. Many offer Portuguese as a second language.

Curriculum and Methodology

National schools: Standardised curriculum with a growing focus on 21st-century competencies. Continuous assessment complemented by national exams.
International schools: Varied curricula with greater flexibility. Tendency towards more student-centred methodologies, with interdisciplinary projects and diverse assessment methods.

Class Size

National schools: Classes of 20 to 28 students, depending on the level and school.
International schools: Generally smaller classes of 12 to 20 students, allowing for more individualised attention.

Costs

Public schools: Free. There may be costs for textbooks, school supplies and extracurricular activities.
Private national schools: Between 300 and 800 euros per month.
International schools: Between 600 and 2,000 euros per month, potentially exceeding this at the most prestigious colleges. Annual tuition typically ranges from 8,000 to 25,000 euros.

School Calendar

National schools: The academic year runs from September to June, with breaks at Christmas, Carnival and Easter.
International schools: Variable depending on the curriculum. British and IB schools tend to follow a calendar similar to the national one. American schools may have a slightly different schedule.

Cost Comparison: A Closer Look

For a family with two children, here is an annual cost estimate:

Public school: 500 to 1,500 euros per year (textbooks, supplies, activities)

Private national school: 7,000 to 19,000 euros per year (tuition, meals, activities)

International school: 16,000 to 50,000 euros per year (tuition, registration, meals, transport, activities)

Note that many international schools charge a one-off registration fee (between 1,000 and 5,000 euros) and may require the purchase of specific uniforms. Some companies transferring staff to Portugal include education subsidies in the expatriation package — it is worth negotiating this point.

Top Areas for International Schools in Lisbon

Cascais and Estoril: The highest concentration of international schools in the region. Includes St. Julian's School, TASIS Portugal and several other options. The area offers a family-friendly lifestyle with beach access and a good transport network.

Carcavelos and Parede: A growing zone with options such as Colégio do Vale and proximity to several international schools in Cascais. Excellent value in the property market.

Sintra: Some international options and a more rural, green setting, ideal for families who value space and nature.

Central Lisbon and Parque das Nações: The Lycée Français and some newer international schools are located here. Ideal for families who work in the city and prefer to avoid long commutes.

Setúbal and the South Bank: More limited but growing options, with significantly lower living costs.

Application Process and Timeline

International Schools

12 to 18 months before: Research schools, visit campuses, attend open days
10 to 12 months before: Submit applications (many schools have waiting lists)
6 to 8 months before: Complete admissions tests and interviews
4 to 6 months before: Confirm placement and pay the reservation deposit
1 to 2 months before: Orientation and integration sessions

National Schools (Public)

April to June: Enrolment period for the following year
Required documents: Proof of residence, child's NIF (tax number), vaccination record, identification documents
Important note: Places are allocated based on the residential area. If you live near the desired school, placement is generally guaranteed.

Making the Transition Smoother

Changing schools — especially across countries — is one of the most challenging moments for a child. Here is how to ease the process:

Visit the school before the first day: Familiarise your child with the premises, the corridors, the canteen and, if possible, introduce them to their future teacher.
Invest in language: If you choose a national school, enrol your child in Portuguese lessons before the move. If you opt for an international school, reinforce their English.
Maintain family routines: In a world of change, daily rituals — family dinner, the bedtime story — become emotional anchors.
Connect with other families: Expat communities in Portugal are active and welcoming. Facebook groups, InterNations events and family meetups can make social integration easier for both parents and children.
Be patient: Full adaptation can take between 3 and 12 months. Celebrate the small victories and avoid putting pressure on your child.

Extracurricular Activities: The Essential Complement

Regardless of school type, extracurricular activities play a crucial role in the integration and development of expat children:

Sport: Football, swimming, tennis and martial arts are excellent for making friends outside the school context
Arts: Music, drama and dance help with emotional expression and confidence
Languages: Supplementary Portuguese classes (if attending an international school) or English classes (if attending a national school)
Nature: Outdoor activities, scouting and holiday camps promote a connection with the new country

Extracurricular activities are often the setting where expat children form their first genuine friendships in their new home.
