International School Brunei

ISB has delivered strong IB Diploma results over three consecutive years, with average scores of 33–33.5 out of 45 and pass rates of 92–98%, well above the global averages of around 30 and 80% respectively. In 2026, 46.5% of students scored 34 points or higher and multiple students achieved the top score of 42. These figures are reported by the school and have not been independently verified.

According to the school's own reporting, every student in the 2026 Year 13 cohort who applied to university received an offer, with 34% of final places at QS Top 50 universities and 88% attending their first-choice institution. Families should note that these figures are self-reported by ISB and the ranking methodology used is not disclosed.

ISB explicitly states that it does not operate an academically selective admissions policy and aims to serve students across a range of ability levels. No formal English language test threshold is published, and families should contact the admissions team directly to understand the process for their child's year group.

ISB offers a merit scholarship for exceptionally talented students who have completed GCE O Level or GCSE examinations and wish to enter the IB Diploma in Years 12–13. Details such as the award amount, number of scholarships, deadlines, and eligibility restrictions are not publicly published, so families should contact the admissions team directly for current terms.

ISB operates two dedicated Centre for Inclusive Learning (CIL) campuses — at Panaga and Bandar — providing specialist SEN provision for students aged 2–13. The CIL won the Tes Awards for International Schools 2025 in the Specialist Provision Provider of the Year category. Families with children who have additional learning needs should contact ISB early to confirm whether the school's current resources can meet their child's specific requirements.

ISB offers boarding through its Residence for students in Years 7–13 only; younger students are not eligible for the residential programme. Published annual boarding fees are BND 16,500 for five-day shared-room boarding and BND 21,500 for seven-day shared-room boarding, in addition to tuition fees. Most boarders are from Brunei, primarily based in Seria or Kuala Belait.

Boardership is ISB's bespoke residential programme for Year 7–13 boarders, focused on leadership development, wellbeing, and life skills rather than just providing accommodation. The programme was recognised when ISB won the Australian Boarding Schools Association (ABSA) International School of the Year Award 2025 for the quality of its international boarding provision.

ISB reports a community of around 1,200 students aged 2–18 drawn from more than 40 nationalities, making it one of the more internationally diverse school communities in Southeast Asia outside a major city. The school does not publish a breakdown of local versus international students, so families seeking that detail should contact the school directly.

ISB holds CIS accreditation, is an IB World School (since July 2000), and is a member of FOBISIA. In 2025 it won two internationally judged awards: the Tes Awards for International Schools in the Specialist Provision Provider of the Year category, and the Australian Boarding Schools Association International School of the Year Award. It also holds Eco-Schools Green Flag status.

ISB integrates sustainability education (through its Eco-Schools Green Flag recognition, Jungle Classroom, and Eco Garden), community service, and the Duke of Edinburgh's International Award — which it has delivered since 2016 — as formal parts of student life rather than optional extras. These reflect the school's philosophy that student development extends well beyond examined academic performance.

International School Brunei follows the UK National Curriculum. Students sit IGCSE and A-Levels.
