Curriculum details
The Australian International School Bangkok (AISB) follows a pathway that combines the Australian Curriculum and the Cambridge International programme. In the Primary Years (Foundation to Year 6), the school uses Australian teaching approaches with a broad curriculum including English, Mathematics, Science, Humanities, Languages, the Arts, and Physical Education. In Lower Secondary (Years 7–8), students continue with the Australian Curriculum while also preparing through Cambridge Lower Secondary courses. In Middle Secondary (Years 9–10), students work towards the Cambridge IGCSE qualifications, which cover a wide range of academic subjects. 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.
1. Book an Open House or school tour. Attending sessions - such as the one held 31 January 2025 - lets you walk the campus, meet teachers, and see the environment firsthand.
2. Submit an application. Once you've visited, complete the online form, attach required documents (e.g. birth certificate, passport) and pay the non-refundable THB 4,000 application fee.
3. Attend assessments and interviews. Pre-Nursery–Year 2 applicants have a parent interview and informal assessment; Years 3–6 take English and Maths tests plus an interview; Years 7–13 complete assessments and meet with the Head of Secondary.
4. Receive results and offer. Within 3–5 working days, the Admissions Team informs you of your outcome and issues an Offer of Place, including a fee invoice.
5. Confirm your child’s place. To secure enrolment, pay the enrolment fee by the deadline and complete tuition payment. At this stage, uniforms and resources can also be purchased.
Admissions
1. Initial Inquiry and Campus Visit Families begin the admissions process by contacting the school directly or visiting the Soi 20 Campus. Parents are encouraged to tour the campus, meet staff, and discuss the suitability of the program for their child’s age group (Nursery to Year 1).
2. Application Submission An application form must be completed and submitted with the required supporting documents (such as passport copies, previous school reports if applicable, and medical records). At this stage, a one-time application is payable.
3. Assessment (if required) For certain year groups or based on the recommendation of the Head of School, an assessment may be required. This incurs an additional assessment fee. The assessment ensures that the child’s needs can be supported effectively within the program.
4. Offer of Placement Once the application and any assessments are complete, the school will issue an offer of placement if a place is available. Parents must then pay the non-refundable registration fee to secure the child’s enrolment.
5. Enrolment and Orientation Tuition fees must be paid before the child begins classes. Enrolment is confirmed only when the first term’s fees have been received in full. Orientation details are provided to help families and students settle into the school routine.
