[7] In February 2023, JIS was honoured with the COBIS Patron's Accreditation[8] and became the first international school worldwide to receive Beacon Status in three standards: Student Welfare, Boarding Provision and Extracurricular, Enrichment & Engagement.

Jerudong International School sits on around 120 acres (49 ha) of private ground in Kampong Tungku.

Students choose to study either the A-Level Examinations[20][21] or the International Baccalaureate (IB) Diploma Programme.

[22] JIS has a particular focus on preparing students for admissions for UK, USA, Australia, and Canadian universities.

[23] 35% achieved over 40 points in the International Baccalaureate, with 96% of its students exceeding the world average IB Diploma score.

[25] The Ugama School was established in Jerudong International School in 2005 mainly to fulfill the need of Bruneian Muslim students for primary religious education, even more so after the codification of Perintah Pendidikan Ugama Wajib Brunei 2012 (literal translation: Brunei Compulsory Religious Education Order 2012).

Under the Order, it is compulsory for parents in which at least one of them is Bruneian citizen to ensure their children who are Muslim, born after 1 January 2006 and reside in the country to attend primary religious school.

[29] The Sports Complex opened in January 2017 and is situated in the area between the main school buildings and boarding houses.

[32] The Arts Centre comprises a theatre, which can accommodate up to 725 guests on normal seating, a Black Box Theatre, an Art Gallery, a Conference Room, Orchestra Rehearsal Room, spaces for exhibition, dance studio and several bespoke drama classrooms.

The ODC has acted as an outdoor classroom showcasing student-led projects such as rewilding, fruit and vegetable gardens, maintaining the hives of our stingless bees, rainwater harvesting and eco-art.

This initiative aims to significantly reduce the carbon footprint and promote renewable energy usage within the JIS campus community.
