Oeiras International School is one of the through school International Baccalaureate options on our Lisbon city hub, a single campus in the coastal municipality of Oeiras that runs the complete IB pathway under one roof. Founded in 2010, it offers the Primary Years Programme, the Middle Years Programme and the Diploma, so a family can settle one child for the whole of their schooling without a curriculum change. The school describes itself as non selective, working to draw out each child rather than screening for entry.

This is an independent profile. GlobalSchoolGuide accepts no payment for inclusion and the school appears on its own merits. The facts below were researched from the school and public sources at the time of writing, and where a figure is not published we say so rather than invent one.

Curriculum and academics

The school teaches the International Baccalaureate from start to finish. Younger pupils follow the Primary Years Programme, an inquiry led approach that ties subjects together around units of understanding. From the middle years the Middle Years Programme broadens into discrete disciplines while keeping the same inquiry spine, and the two final years lead to the IB Diploma, the qualification most international universities recognise. Because all three programmes sit on one campus, the transition between stages is internal rather than a move to a new school.

The IB Diploma asks students to take six subjects across the disciplines alongside the core of theory of knowledge, the extended essay and creativity, activity and service. Families weighing that breadth against the depth of three or four A levels offered elsewhere in the city can read our IB curriculum guide and compare the route against the British schools nearby before deciding.

Oeiras International School fees

Oeiras International School publishes tuition by age group, and the headline figures rise from the early years to the Diploma, which places a senior place in the mid to upper part of the Lisbon market and an early years place lower down. Treat any single number as a starting point and read it against the bands in our Lisbon international school fees guide, where a typical mid market senior tuition sits around the middle of the city range and the most expensive schools run higher.

Budget for the extras that attach to an IB school. The school charges a one off application fee per applicant, and transport is priced separately for one way or return journeys. Add the usual lines a parent must plan for, registration, any deposit, and meals, then model a full year before committing. Our fee tools let you build that total quickly.

Admissions

Admission runs to the standard international school rhythm, with the main intake in September at the start of the academic year and places filled through the year where a year group has space. The school is not academically selective, so the process is about fit and placement rather than a competitive entrance examination, though older applicants to the Diploma are matched to subjects and prior study.

Families should expect to submit recent school reports and references, pay the application fee, and meet the admissions team. For a Diploma entry it helps to arrive with a clear sense of subject choices and any prior IB or equivalent study. Confirm the current intake dates and document list directly with the school.

Location and who goes there

The campus is in Oeiras, the coastal municipality between central Lisbon and Cascais, a belt where many relocating families already choose to live for the sea air, the train line into the city and the cluster of international schools. The location suits families settling west of Lisbon who want a through school within a reasonable commute rather than a daily drive into the centre.

Because it runs the full age range, the community spans toddlers to school leavers and reflects the internationally mobile families of the Oeiras and Cascais corridor. Parents comparing it with other options can use the Lisbon city hub and our best IB schools in Lisbon shortlist to see where it sits in the wider market.

Reviews

We do not yet have verified parent reviews for Oeiras International School. GlobalSchoolGuide is independent and no school pays to be listed, so we publish reviews only once we can confirm they come from real families. If your child attends or has attended this school, we would value your first hand account. Share your experience through the school reviews hub and help the next relocating family decide with better information.
