How do you enrol a child in a public school in Portugal in 2026?

Compulsory education covers ages 6 to 18. It ends when the student completes secondary education (normally through year 12) or turns 18. First enrolment in year 1 of basic education is mandatory for children who turn six by 15 September. Children who turn six between 16 September and 31 December may enrol if places remain.

Parents can express school preferences, but when demand exceeds places the agrupamento (school grouping) applies priority criteria. A place in the public network of the residence area is guaranteed for a child of compulsory age, even if the preferred school is full. Overcrowding can push assignment to the nearest available school. A stable Portuguese address therefore matters before you lock Cascais or Porto housing: living in Lisbon and living in Porto.

Portal das Matrículas is the Ministry of Education online service for many first enrolments and renewals with school transfer in preschool, basic, and secondary public schools (and some private or IPSS settings). Guardians usually authenticate with Cartão de Cidadão, Chave Móvel Digital, or Portal das Finanças credentials. If online filing fails, submit in person at the main school of the residence agrupamento.

Enrolment seasons open on Ministry calendars each spring for the following school year. Foreign-system equivalences, mid-year transfers, and some specialised tracks often stay on school-counter procedures. Bring identity documents for parent and child, proof of Portuguese address, a NIF when asked, and prior school records with translations or equivalences as directed.

State schools teach mainly in Portuguese. Schools organise Portuguese as a second language or similar support for pupils who arrive without fluency, but the day-to-day classroom and parent notices still assume Portuguese. That is a different budget and language decision from fee-paying campuses covered in international school costs. Public tuition for compulsory schooling is free; books, meals, and transport can still add costs, and family social support (ação social escolar) depends on household means.

Family movers often compare neighbourhoods through expat families communities and shortlist cities with best places for families before locking a lease that defines catchment.
