Social & emotional learning	Social & emotional learning 1) Social and emotional learning (SEL): ISO supports SEL through its Student Life structure, notably the Student Society which engages students in activities that promote social and emotional development, leadership, teamwork, and positive attitudes. 2) After-school clubs extend SEL by offering diverse clubs that foster belonging, collaboration, and personal growth. 3) Pastoral care is highlighted as a mechanism to safeguard and support students' social and emotional well-being within a secure, nurturing environment. 4) The overall approach to student welfare emphasizes social and emotional development as part of a well-rounded education. 5) These elements reflect a holistic emphasis on SEL across both curricular and extracurricular activities.

English as an additional language NWIS offers an English as an Additional Language (EAL) immersion programme designed to help all students access the curriculum taught in English. The programme aims to develop English for academic purposes and to narrow gaps in proficiency, with an immersive approach. Students receive five hours of EAL support per week, including three integrated classroom sessions and two pull-out one-to-one sessions focused on speaking and writing.
