Introduction

The AISB Sukhumvit Soi 20 Campus, founded in 2002 as the school’s original site, serves children from 18 months to around five years old (Nursery 1 to Year 1) in a residential pocket of central Sukhumvit. The campus constructs its early learning around the Australian Early Years Learning Framework ‘Belonging, Being and Becoming’, promoting inquiry-based and play-centred experiences. Instruction is in English, and staffing includes native, qualified teachers. A co-curricular program incorporates art, music, sports, sciences and digital technologies—giving children opportunities to explore STEAM and creative expression from the outset. Daily bus and shuttle services ensure smooth journeys for local families and connectivity to the Upper Primary & Secondary campus on Soi 31. With low student numbers per class (typically 15–18) and a nurturing, tightly knit setting, the Soi 20 campus offers a welcoming first step into school life.

The Essentials

Australian International School Bangkok - Soi 20 has 900 pupils, typical class sizes of 16, instruction in English.

Location
The AISB Soi 20 Campus is located at 162/2 Sukhumvit Soi 20, Klong Toey, Bangkok. It sits in a central residential area of Sukhumvit, surrounded by apartments and within easy reach of major roads and public transport. Many families live nearby, allowing some children to walk to school.

Stages
The Soi 20 Campus caters for Early Years education, serving children from 18 months (Nursery 1) to around 5 years old (Year 1). After this stage, children typically transition to the Soi 31 campus for Primary School.

Type
The school is co-educational.

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 20 campus, the day is tailored to Early Years and younger Primary students. Nursery runs from 08:30 to 12:00, while Pre-Kindergarten 1 (Pre K1) operates from 08:30 to 12:10, and Pre-Kindergarten 2 (Pre K2) from 08:30 to 13:00. Foundation classes (at Soi 20 only) begin earlier, from 08:00 to 13:45. Year 1 students also start at 07:30, with classes finishing at 14:10. These timings reflect a shorter day for the youngest children and a gradual transition to longer school hours before moving on to Soi 31 for Foundation–Year 12.

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.
Diving Deeper

Uniform Requirement
The school requires students to wear the approved school uniform when attending on-site classes. The Uniform Shop is open on Saturdays from 09:00 to 12:00 and on weekdays from 08:30 to 16:00; visits on weekdays require an appointment. Uniforms are not required on remote learning days.

Food Options
Nutritious snacks and lunches are available daily. The school accommodates vegetarian diets, but students with dietary needs other than vegetarian diets must supply their own lunch. The school has a nut-free policy on both campuses.

House System
The school uses a house system that groups students across year levels to foster tradition, school spirit and teamwork through whole-school activities. There are six houses: Acacia, Grevillea, Telopea, Eucalyptus, Wollemi and Correa.

Governance and Ownership
The school is governed by AISB leadership with an Advisory Board and an Executive Board providing governance and strategic guidance.

Academics

Australian International School Bangkok - Soi 20 teaches Australian Curriculum for students aged 1.5 to 5.

Curriculum
The Soi 20 Campus of the Australian International School Bangkok delivers the Australian Early Years Learning Framework (EYLF): “Belonging, Being and Becoming.” This program is designed for children aged 18 months to around 5 years, covering Nursery, Pre-Kindergarten, Pre-Kindergarten 2, Foundation, and Year 1. The framework emphasizes play-based and inquiry-based learning, encouraging children to explore literacy, numeracy, social development, and creative expression through structured and guided activities. Specialist subjects such as music, art, and physical education are integrated into the program, alongside daily English language development. For students requiring support, English as an Additional Language (EAL) is offered, with small-group or intensive sessions as recommended. After completing Year 1, students transition to the school’s Soi 31 Campus, where they continue into the Australian Curriculum for primary years and later progress into Cambridge IGCSE, AS Level, and A Level qualifications at secondary level.
