Introduction

Australian International School Bangkok’s Soi 31 campus offers education from Foundation to Year 12 in the heart of Sukhumvit, Bangkok. Established in 2002, the school combines the Australian Curriculum in the early years with Cambridge Lower Secondary, progressing to IGCSEs in Years 9–10 and culminating in AS and A Levels. The campus is home to the AISB Innovation & Sports Centre, which supports integrated STEAM learning alongside extensive sports and performing arts programmes. Students study in English, with Thai compulsory and additional languages including French, Mandarin, Japanese, and German. The school community includes over 800 students from diverse backgrounds, supported by co-educational classes and a supervised transport system that links both campuses. Notable initiatives include the school’s Eco-Schools sustainability programme and its well-regarded Chess Academy, which offers specialist training and competitions. Together, these features make AISB’s Soi 31 campus a distinctive choice for families seeking international education in Bangkok.

The Essentials

Australian International School Bangkok - Soi 31 has 800 pupils, typical class sizes of 15, instruction in English.

Location
Australian International School Bangkok’s Soi 31 campus is nestled at 319 Sukhumvit Soi 31 in Bangkok’s Watthana district. It resides in a quiet, leafy residential area of central Sukhumvit, offering a calm environment while remaining well connected—taxis, BTS/MRT stations, and main road access are convenient. The campus shares proximity with the AISB Sports Centre and Innovation Centre and is just minutes away from the Soi 20 campus, connected by a supervised shuttle service, making transitions and shared activities easy.

Stages
AISB operates a two-campus model: Soi 20 serves the Early Years (Nursery and Year 1), while the Soi 31 campus accommodates the full range from Foundation (Year 1) through to Year 12. This structure clearly distinguishes the youngest learners’ setting from older primary and secondary students, with most of the Foundation–Year 12 progression housed on Soi 31.

Type
AISB operates as a day school.

Additional learning support
Support services include a structured EAL program with small-group and intensive options, along with a Learning Support department that provides personalized plans, assessments, and teacher collaboration. The Access and Inclusion teacher coordinates extra help with internal staff and external specialists as needed.

Country affiliation
While not formally affiliated with the Australian government, the school’s curriculum and identity are strongly influenced by Australian education.

Religious affiliation
The school has no religious affiliations.

School day structure
At the Soi 31 campus, the school day begins at 07:30 for both Primary and Secondary students. Primary classes (Foundation to Year 6) finish at 14:00, while Secondary (Years 7–12) end at 14:50. Breaks and lunchtime are built into the timetable, with meals provided daily on campus. Early Years (Nursery to Pre-Kindergarten) are housed at the Soi 20 campus and follow shorter hours, but Foundation (from Year 1 onwards) transitions fully to Soi 31.

Bus service
AISB provides optional transportation in partnership with Montri Transport, a well-established Bangkok school transport provider. The service is door-to-door and includes both a driver and an adult supervisor on every route. Terms and conditions for the service are available directly from Montri upon request. This option gives families flexibility and additional safety for young children.

The final stage, Senior Secondary (Years 11–12), offers the Cambridge AS and A Levels, providing internationally recognised qualifications for university entrance. Throughout all year levels, students also study Thai language and culture, with additional options in French, Mandarin, Japanese, and German for native speakers.

Academic calendar
Wellbeing

Social and Emotional Learning (SEL)
At Soi 31 Secondary, Positive Education is built into the daily timetable, with regular sessions on bullying, resilience, goal setting, cyber safety and positive psychology led by teachers. Primary (Years 1–6 at Soi 31) delivers a Health & Wellbeing program that explicitly teaches social skills, resilience and optimism, with monthly assemblies reinforcing protective behaviours. The Secondary page further notes a scope-and-sequenced Positive Education curriculum taught regularly. School-wide Student Support Services emphasise personal growth and socio-emotional development alongside academics. These provisions apply to students educated on the Soi 31 campus (Foundation–Year 12).

Special Educational Needs (SEN)
AISB provides Learning Support that includes targeted 1:1, small-group and in-class support, Individual Learning Plans, and collaboration with parents and teachers; these services are available to Soi 31 students. The Access and Inclusion program supports students with identified learning disorders (e.g., dyslexia) and, where appropriate, coordinates with external specialists such as speech and occupational therapists. Guiding principles include confidentiality and a strengths-based approach. The website describes SEN as support within AISB’s mainstream provision rather than a specialist SEN school.

English as an Additional Language (EAL)
There is a full-time EAL teacher on each campus, including Soi 31, who assesses learners, plans curriculum-aligned support with homeroom teachers and families, and exits students when they reach independent English proficiency. Provision includes Regular EAL (3 sessions/week) and Intensive EAL (5 sessions/week), each 45 minutes with a maximum of 6 students per class. Instruction starts with a focus on spoken language and progresses toward more written-like language as skills develop.

Mental Wellbeing
Primary students at Soi 31 receive explicit instruction in health literacy, emotional wellbeing and protective behaviours through the Health program and monthly assemblies. Secondary embeds Positive Education daily, addressing age-specific issues such as bullying and cyber safety. The Soi 31 Secondary Highfield building includes a Nurses Room and a Student Counsellor’s Room, supporting on-site wellbeing. Outdoor Education and service learning in Secondary further develop empathy, leadership and teamwork. Student Support Services frame socio-emotional development as a core element alongside academics.

Safeguarding
The school does not publicly disclose specific safeguarding or child protection policies on its website.
