How to Enroll Your Child in a Public School in Lisbon

Children enter Portugal’s public schools through the Portal das Matrículas, the Ministry of Education’s online enrollment portal, used for first enrollment in pre-school and 1st grade and for renewals at key transitions. For the 2026/2027 school year, first enrollments for pre-school and 1st grade ran from 22 April to 1 June 2026. Families who arrive after the deadline apply directly to a school cluster (agrupamento de escolas).

Dates and requirements below are from the Portal das Matrículas and the Directorate-General for Education (DGE), as of November 2026. Public schooling is free, and Portuguese schools enroll children who live in the country, whatever their nationality.

When are the enrollment periods?

The Ministry sets new enrollment windows every year. For 2026/2027 the portal published:

Renewal through the portal is required on the transition to 5th, 7th, 10th and 12th grade, and in other years only when you want to change school, change the guardian (encarregado de educação), change course or choose subjects. Expect the 2027/2028 windows to be announced in spring 2027.

How do I enroll on the Portal das Matrículas?

You log in, choose up to several schools in order of preference and upload the documents. According to the portal, have these ready:

1. your own ID document and your child’s ID document;
2. a digital photo of your child;
3. your NIF and your child’s NIF (Portuguese tax numbers);
4. your child’s Social Security number (NISS), only if you want to apply for school social support (Ação Social Escolar), such as free meals and help with books.

Log in with the Cartão de Cidadão, the Chave Móvel Digital (Portugal’s digital ID) or your Portal das Finanças credentials. Use the portal’s school-network search to see the schools near your home. Places are allocated using national priority rules, which take into account factors such as where the family lives, so the schools you list near your address matter.

If your child needs a NIF first, see how to get a NIF in Portugal; for the NISS, see how to get a NISS.

What if we arrive after the deadline or mid-year?

Children arriving from abroad can generally enroll outside the normal windows, subject to available places. Go to the office (secretaria) of a school cluster near your home with ID documents for you and the child, your address and any school reports from the previous country. The cluster places the child in a school with space, which may not be the nearest one.

Children who studied abroad need their previous schooling recognized to be placed in the right year. For pupils with foreign school records, the DGE says the usual equivalence procedures are handled by the school, outside the portal. Bring report cards and, if possible, a document showing the school years completed; ask the school whether translations are needed.

Lack of documents should not keep a child out of school. Portuguese law guarantees minors access to education and health even when their parents’ residence status is not yet regular, and schools can start the process while the NIF or residence permit is pending. If a school refuses, ask for the refusal in writing and contact the regional education services (DGEstE).

What support is there for children who do not speak Portuguese?

Public schools offer Portuguese as a non-native language (Português Língua Não Materna, PLNM). Under Portaria 29/2025, a school-made diagnostic test places each pupil at a level:

The DGE recommends a settling-in period before the diagnostic test. Pupils at initiation or intermediate level can sit national PLNM exams in 9th and 12th grade instead of the Portuguese exams. Ask the school how many PLNM hours it offers, since the timetable depends on the number of pupils.

What does the school year look like?

The school calendar is set each year by a ministerial order (despacho) published in the Diário da República, and runs from mid-September to June, with breaks at Christmas, Carnival and Easter. Schools publish their own term dates, test periods and holidays, which can differ slightly between clusters. Bank holidays also close schools; see public holidays in Portugal.

Pre-school (educação pré-escolar) is for ages 3 to 5. Compulsory schooling covers 12 years, from 1st grade to the end of secondary school (12th grade) or age 18. Ask the school cluster about after-school and holiday activities, which vary by school.

Bottom line

If you are moving in spring or summer, get your child’s NIF before the enrollment window opens, because the portal requires it. If you arrive mid-year, skip the portal and go straight to a school cluster office with your documents; a missing residence permit is not a legal reason to refuse a place.

FAQ

Can I choose any school in Lisbon?

You can list several schools in order of preference, but places go by national priority rules when demand exceeds supply. Popular schools fill with pupils who meet higher priorities.

Is there a cost for public school?

Tuition is free. Families may pay for meals, extra activities and some materials, with reductions through Ação Social Escolar for lower-income households.

Can my child go to an international school instead?

Yes. Private and international schools in the Lisbon area set their own admissions and fees, outside the Portal das Matrículas.
