School-reported facts; source links are provided below.

An IB school in Oeiras

Oeiras International School is listed in the International Baccalaureate’s official school directory. Its educational provision includes the IB Diploma, which gives older students a route towards university study. The IB listing provides a source separate from the school’s own website for checking programme authorisation.

The available evidence in this profile does not establish every current age group. Confirm the intended grade directly with OIS before making a shortlist based on age. For Diploma entry, ask about subject combinations, language options and how the student’s existing qualifications meet the entry requirements.

IB programmes checked against the awarding body

The International Baccalaureate directory lists Primary Years, Middle Years and Diploma coordinators for Oeiras International School. It records English instruction and day-school provision. These entries provide an awarding-body source alongside the school’s own information.

Barcarena campus address

The IB directory gives the campus as Quinta da Nossa Senhora da Conceição, Rua Antero de Quental 7, Barcarena–Oeiras, 2730-013. The Oeiras listing therefore refers to this campus rather than a location in central Lisbon.

Age guidance: an inconsistency to resolve

The current school overview describes pupils aged 6–18, with PYP at 6–10, MYP at 11–16 and Diploma at 17–18. The admissions policy separately says it accepts children from five. We show the current programme range here; families applying for a five-year-old should obtain an explicit placement decision.

Admission priorities and individual review

The admissions policy gives priority to continuing pupils, staff and founding-member families, then siblings. Other applications depend on available space and the admission procedure. School records and an interview help the school assess placement and support; the policy’s lower entry age of five differs from the current programme overview.
