Satit International Bilingual School of Rangsit University

A Unique Bilingual Philosophy

Satit Bilingual School of Rangsit University (SBS) was founded on a distinctive educational philosophy: that Thai students — and the international families who join them — need not choose between rigorous local cultural grounding and globally recognised academic credentials. Instead, SBS offers both simultaneously.

English and Thai as Co-Equal Languages of Instruction

Unlike many international schools in Bangkok that use English overwhelmingly as the sole medium of instruction, SBS operates a genuinely bilingual model in which English and Thai are treated as co-equal languages of learning. This means students develop academic literacy in both languages across core subjects, an approach that has significant advantages for Thai graduates who will operate professionally in both local and international environments.

Dual Curriculum: IB and Cambridge

The academic programme draws on two of the world's most respected international frameworks. The Cambridge International pathway — including IGCSE at the secondary level and A-Levels or equivalent — provides a structured, subject-specialist route toward university. Complementing this, SBS became an IB World School on 26 October 2018, authorised to offer the IB Diploma Programme (IBDP). The IBDP's emphasis on critical thinking, the Theory of Knowledge, the Extended Essay, and Creativity, Activity, Service (CAS) rounds out the more subject-focused Cambridge approach, giving students a broader intellectual formation.

Holistic Development

Beyond academic achievement, SBS places clear emphasis on whole-child development. The school offers a diverse extracurricular programme spanning sports (football, swimming, basketball, taekwondo), performing arts (drama, music ensembles), STEM (robotics, programming), and community service. The presence of a full-time school psychologist and dedicated EAL/TAL support teachers reflects an institutional commitment to student wellbeing and inclusivity.

University Preparation

As articulated by the school's founder Apiramon Ourairat in an interview with The Nation Thailand, the school's ultimate aim is to prepare students for admission to universities worldwide — a goal evidenced by the adoption of both IB and Cambridge credentials, which are recognised by universities across Asia, Europe, North America, and Australia.

In summary, SBS's philosophy rests on three pillars: genuine bilingualism (English and Thai), internationally validated academic rigour (IB + Cambridge), and holistic personal development — all delivered within a Thai cultural context that the vast majority (93%) of its student body calls home.

Academic Programme Overview

Satit Bilingual School of Rangsit University provides one of the rare dual-track academic experiences in the Bangkok metropolitan area, combining the Cambridge International Examinations pathway (IGCSE and A-Levels) with the IB Diploma Programme under one roof.

Cambridge Pathway (IGCSE and A-Level)

The Cambridge pathway begins in earnest in the secondary years. Students at the IGCSE level study a broad range of subjects including English Language, English Literature, Mathematics, the three sciences (Biology, Chemistry, Physics), Business Studies, Computer Science, Thai Language, and Thai Society & Culture. This breadth ensures that no matter what direction a student ultimately chooses at university, they have covered the essential academic building blocks.

At the A-Level stage, students narrow their focus to three or four subjects chosen from a menu that typically includes Mathematics, Further Mathematics, Biology, Chemistry, Physics, Business, Economics, and English — disciplines well-suited to both STEM-oriented and humanities-leaning students.

IB Diploma Programme

Authorised since October 2018, the IBDP at SBS allows students to pursue the internationally recognised IB Diploma, studied over two years (equivalent to Years 12–13). The IBDP requires students to study six subjects (three at Higher Level, three at Standard Level), complete a 4,000-word Extended Essay, undertake Theory of Knowledge (TOK), and fulfil 150 hours of Creativity, Activity, Service (CAS). The IB Diploma is particularly valued by universities in the United States, United Kingdom, Netherlands, and across the Asia-Pacific.

Class Sizes and Staffing

According to third-party data, class sizes at SBS vary by age group: Toddler classes average 14 students, Early Years classes average 21, and Years 1–13 classes average 26 students. All classrooms are equipped with LCD projectors, and the campus is wired with both LAN and wireless networking, supporting technology-integrated learning.

EAL and Learning Support

Recognising that a bilingual school will always have students whose dominant language is either English or Thai (but not both), SBS employs dedicated EAL/TAL (English as an Additional Language / Thai as an Additional Language) teachers who provide individualised support. A Special Educational Needs (SEN) programme is also in place, ensuring that students with additional learning requirements can participate fully in both classroom and whole-school settings.

Campus and Facilities

Located in the Muang Ake district of Pathum Thani — approximately 30 kilometres north of central Bangkok — Satit Bilingual School of Rangsit University occupies a self-contained campus adjacent to Rangsit University itself. The setting provides a degree of spaciousness that is difficult to replicate within Bangkok city limits.

Academic Facilities

The school is equipped with multiple science laboratories fitted with modern apparatus and safety equipment, dedicated ICT laboratories for computing and programming, and multimedia centres housing audio-visual resources for creative and presentation work. All classrooms are connected to the school's LAN and wireless network and are equipped with LCD projectors — a baseline of technological infrastructure that supports SBS's technology-integrated teaching approach.

Sports Facilities

SBS's sports offering is noteworthy. The centrepiece is an Olympic-size swimming pool, which supports competitive swimming as well as recreational use. A full-size football pitch, a well-equipped indoor gymnasium (used for basketball, badminton, volleyball, and indoor sports), and dedicated outdoor play areas for younger students round out the sports infrastructure. These facilities directly underpin the school's broad extracurricular sports programme.

Boarding

SBS operates on-site boarding accommodation, making it one of a small number of bilingual international day-and-boarding schools in the Bangkok metropolitan region. The dormitory buildings are segregated by gender, provide Wi-Fi connectivity, and are supervised by resident dormitory teachers and nursing staff around the clock. Boarding is available from approximately Grade 3 (around age 8) onwards, catering primarily to students from upcountry Thailand or families living at a distance from the campus.

Campus Atmosphere

With approximately 1,092 students from 11 nationalities, SBS strikes a balance between the scale needed to offer diverse programmes and a community feel. The predominantly Thai student body (93%) gives the school a distinctly local character even within its internationally framed curriculum — students move between English and Thai naturally throughout the day, and the school's co-curricular calendar reflects both Thai national celebrations and international events.

Location and Access

The campus address is 52/347 Muang Ake, Phahonyothin Road, Lak Hok, Mueang, Pathum Thani 12000. It is accessible from central Bangkok via the Phahonyothin expressway or public transport to Rangsit, with the school providing five shuttle bus routes serving surrounding residential areas.

Community and School Culture

Satit Bilingual School of Rangsit University occupies an unusual position in the Bangkok international school landscape: it is technically an international school offering IB and Cambridge qualifications, yet its student body is overwhelmingly Thai (approximately 93%). This demographic profile gives SBS a community character that is quite different from schools that primarily serve expatriate families.

A Thai-International Hybrid Community

For Thai families, SBS offers a pathway to international academic credentials without requiring immersion in a predominantly foreign-national peer group. Students grow up bilingually — moving between English and Thai throughout their school day — and develop close friendships within a community that shares their cultural background. For the 7% of students from international backgrounds (spanning 11 nationalities), this environment offers an unusually deep immersion in Thai language and culture, which can be a significant advantage for families on longer-term postings in Thailand.

Student Life and Extracurriculars

The school's extracurricular programme is broad. Students can participate in competitive sports (football, basketball, swimming, taekwondo, athletics), perform in music ensembles and drama productions, engage in academic competitions (mathematics and science olympiads, Model UN, debate, chess), and contribute to community through service clubs and the student council. A robotics and STEM club reflects the school's forward-looking approach to technology education.

Support Systems

SBS invests in student wellbeing infrastructure. A full-time school psychologist provides counselling support, and a nurses' room with medical staff is available on campus. The EAL/TAL programme ensures that students whose stronger language is either English or Thai receive the support they need to thrive academically in both languages. A Special Educational Needs (SEN) programme further broadens the school's inclusivity.

Boarding Community

For boarding students — primarily those from upcountry Thailand — the dormitory buildings provide a supervised residential community with round-the-clock dorm teachers and nursing support. This residential dimension adds a layer to the SBS experience that is absent from most Bangkok international day schools, fostering independence and close peer relationships among students who share their weekday lives on campus.

Admissions and Fees at SBS Rangsit

Satit Bilingual School of Rangsit University publishes a transparent fee schedule on its official admissions page, making it possible for prospective families to plan their investment in advance. The school does not publish formal selectivity data or acceptance rates, suggesting an admissions process that is accessible rather than highly selective.

One-Time Fees on Entry

Upon acceptance, new families are required to pay:

• Admission Fee: THB 85,000 (non-refundable, one-time payment). This is classified as an enrolment confirmation fee.
• Student Deposit: THB 50,000 (refundable on graduation or departure from the school).
• Security Deposit: THB 5,000 (refundable, purpose-designated for security/materials).

The total upfront non-tuition commitment for a new family is therefore THB 140,000, of which THB 85,000 is non-refundable.

Annual Tuition by Grade

Tuition fees (2025–2026 academic year) range from THB 218,000 per year at the Nursery/Kindergarten level to THB 332,800 per year at Grades 10–12 (M4–M6), reflecting the increased staffing and examination costs at the senior secondary level. The full fee schedule is:

Sibling Discounts

SBS offers a meaningful sibling discount programme: a 10% reduction on tuition for the second enrolled sibling, rising to 20% for the third child and beyond. This policy makes multi-child family enrolment significantly more affordable and signals a school culture that values long-term family relationships.

No Scholarship or Financial Aid Programme

As of the research date, SBS does not publish any formal scholarship or needs-based financial aid programme. Families seeking fee support should enquire directly with the admissions office to confirm current policy.

Transport

The school operates five shuttle bus routes serving the surrounding Pathum Thani and Rangsit residential areas, with an annual fee example of THB 14,000 for Route 1 (round trip). This provides an accessible transport solution for families not located immediately adjacent to the campus.
