Comparing schools in Oeiras
This page currently covers 1 school listed in Oeiras, Portugal. The listing is Oeiras International School. Coverage is growing and does not represent every private school in the area.
OIS is in Barcarena, with age guidance to clarify
Oeiras International School uses a Barcarena campus at Rua Antero de Quental 7. Its current programme overview describes PYP at 6–10, MYP at 11–16 and Diploma at 17–18. The admissions policy also refers to entry from five; an application for a five-year-old needs a specific placement decision.
Continuing pupils and specified school-community families have priority, followed by siblings. Families transferring into an IB programme should share school records and discuss language and learning-support requirements early. Porto Salvo’s International Sharing School is a separate campus and listing within the wider regional search.
