Overview
Established in 2010, the English-speaking school offers the International Baccalaureate program throughout all year groups. The school caters for students from Year 2 through to Year 13, having previously hosted only students in Years 7 through 12 during its inaugural academic year (2010/11) and expanding to include students in the IB Primary Years Programme in later years.[2]
The school campus is based on the premises of a 17th-century palace,[2][3] the Quinta de Nossa Senhora da Conceição in Barcarena, Oeiras. The 5 hectare campus was refurbished in 2011.[2] During its inaugural year (2010/2011), the school opened at temporary premises, located at Fundição de Oeiras,[4][5][6][7] but has since been located at its present campus.[2] OIS purchased an additional property in 2026, and has plans to open these premises for MYP and DP students starting in the 2026–2027 school year.
OIS became an Eco-School and additionally received the Green Flag Award in the 2024/2025 school year. OIS intends to promote Environmental Awareness and Social Responsibility with the provision of scholarships and community service.[5][6] OIS offers The Duke of Edinburgh's Award for students in Year 9 and above.[8]
