Belonging, inclusion, and physical and emotional safety are foundational to learning at OIS. The Behaviour Policy aligns with the IB Learner Profile to guide respectful interactions and everyday practice. The school provides equal education opportunities and a non-discriminatory environment. A safe, caring environment supports students' social and emotional development.
A learning support programme exists as part of OIS's inclusive IB World School approach. Applicants with severe emotional and intellectual needs cannot be catered for.
The language of instruction is English. Portuguese and English are core languages studied. German, French, Spanish and Mandarin Chinese are offered as first languages and as language acquisition options. In the MYP, language acquisition is taught for three lessons per week. All potential students undertake an English placement test to determine language development.
Wellbeing is a central focus, with Wellbeing Awareness Year celebrating wellbeing topics monthly and involving school psychologists in talks on resilience and mental health. One Tribe Week explicitly focused on belonging and mental health, with mixed-age activities and staff support. Tutors, teachers, the nurse, student support and the psychologist are available to help as needed.
The school protects the rights of all children, following Portuguese law and the United Nations Convention on the Rights of the Child. A Child Protection and Safeguarding Policy guides how safeguarding concerns are handled, with mechanisms to react and respond if abuse is noticed or reported.
