In 2019, JIS became the first international school in the world to receive the 'Outstanding' category when inspected by the UK Ofsted appointed Penta organisation.
In 2023, Jerudong International School received the 'Beacon' Status from COBIS (Council of British International Schools) in three areas. These are Standard 2: Student Welfare
Standard 6: Boarding
Standard 10: Extra-Curricular, Enrichment and Engagement
It is the only school in the world to have achieved Beacon Status in three areas.
Jerudong International School is a vibrant, warm, friendly school. The independent Good Schools Guide commented in their review "At the risk of overpraising the school, there is one final observation to be made. This concerns the infectious enthusiasm you feel absolutely everywhere on campus - the surest and most noticeable sign of a very healthy school.”
