TSI follows the British National Curriculum, but it has no formal affiliation with a specific country.

There is no religious affiliation. It operates as a secular international school.

TSI International School – Wongwianyai Campus follows the British National Curriculum, covering Early Years Foundation Stage (Pre-Nursery “Little Lions,” Nursery, and Reception) through Key Stage 2 (Years 1–6). In the Early Years, the curriculum focuses on the seven areas of learning set out in the UK’s EYFS framework, including communication and language, literacy, numeracy, and physical development. From Year 1, pupils study core subjects such as English, mathematics, and science, alongside humanities, arts, music, physical education, and computing. The programme also incorporates Thai Language and Culture for all students, with additional language options including Punjabi, Hindi, and Chinese. Specialist teachers deliver lessons in subjects such as PE, art, music, and STEAM (Science, Technology, Engineering, Arts, and Mathematics). By the end of Year 6, students are prepared to transition to Key Stage 3 at the school’s Bangna Campus, where the curriculum progresses toward Cambridge IGCSE and A-Level qualifications.

1. Arrange a campus tour.
You can set up a visit on weekdays at either the Wongwianyai or the Bearing campus to see the learning environment for yourself.

2. Pre-testing and documentation.
Parents must submit the child’s three most recent school reports, and the child visits the campus for an age-appropriate assessment and a meeting with staff.

3. Secure your child’s place.
If your child is offered admission (usually within 48 hours of the assessment), it is confirmed once you pay a non-refundable deposit of THB 20,000.

4. Complete the application process.
You’ll need to provide a passport-style photo, birth certificate, recent school reports, and for non-Thai students, copies of passports and parents’ documents.

5. Fee payment.
The school requires partial or full payment of fees before your child’s first day, with a range of payment options available. Once everything is in place, your child begins at TSI and becomes part of the school community.

There is no information on the official website indicating that TSI offers scholarships or financial aid.

TSI places applicants in a wait pool when a class is full. Should space become available later in the year, applicants in the pool may be offered admission.
