Anglo Singapore International School

Humble Beginnings, Ambitious Vision

Anglo Singapore International School (ASIS) was established in 2003 by Ms. Julie Sutanto, a Singaporean entrepreneur who identified a gap in the Thai education market: quality Singapore-standard schooling for expatriate families living in Bangkok. Starting with just four students at a modest location on Sukhumvit Soi 31, the school's founding philosophy was clear — to "provide the same standard of education found in Singapore and the UK."

Rapid Expansion

The school's reputation grew quickly as expatriate and locally resident international families discovered its rigorous bilingual curriculum and welcoming community. By 2011, just eight years after opening, ASIS had grown to approximately 500 students representing over 20 nationalities. This success created both opportunity and necessity for expansion.

In 2012, ASIS opened its second Bangkok campus on Sukhumvit 64, located conveniently near the BTS Punnawithi station. This new campus provided additional capacity and extended access across the greater Bangkok area. Two years later, in 2014, a third campus was inaugurated in Nakhon Ratchasima (Korat), making ASIS the only international school of its curriculum type in Thailand's northeastern region.

Today's Institution

Over two decades, ASIS has grown from a small community school into a multi-campus institution enrolling approximately 1,650 students. The school has maintained its founding ethos while evolving its offerings to include Cambridge IGCSE and A-Level qualifications alongside the Singapore curriculum. The three campuses — Sukhumvit 31, Sukhumvit 64, and Korat — each serve distinct local communities while sharing common values, curriculum frameworks, and quality standards.

Ms. Sutanto remains a central figure in the school's leadership and identity. Her original vision of bringing world-class Singaporean and British education to Thailand continues to shape ASIS's strategic direction and day-to-day educational culture.

A Hybrid Curriculum Model

Anglo Singapore International School occupies an unusual niche in the Thai international school landscape: it is neither a pure British school nor a conventional Singapore-curriculum institution, but a deliberate fusion of both. The school's curriculum framework follows Singapore's Ministry of Education (MOE) guidelines while incorporating key elements from the UK's Cambridge International Examinations system.

This means students benefit from Singapore's internationally renowned mathematics and science pedagogy — consistently ranked among the world's best in PISA assessments — while also preparing for globally recognized Cambridge IGCSE and A-Level qualifications that open doors to universities across the UK, Australia, the United States, and beyond.

STEM as a Core Pillar

Science, Technology, Engineering, and Mathematics (STEM) education is a defining feature of the ASIS experience. The school's facilities reflect this priority: state-of-the-art science laboratories equipped for biology, chemistry, and physics experiments are present across all campuses, along with dedicated computer laboratories for technology and programming education.

This STEM emphasis aligns naturally with the Singapore curriculum tradition, which has long placed mathematics and sciences at the heart of its framework. ASIS graduates who pursue higher education frequently enter engineering, medicine, and science faculties — a pattern explicitly noted in the school's own publications.

Holistic Education and Multilingualism

Beyond academic rigor, ASIS articulates a commitment to holistic education — developing the whole student across intellectual, physical, social, and creative dimensions. The school's core values of Diligence, Respect, Responsibility, and Progress underpin daily school life and are woven into both curricular and co-curricular programming.

A distinctive feature of ASIS is its trilingual educational environment. English serves as the primary language of instruction across all subjects, while Thai language study is compulsory as a local language requirement. Additionally, students can study their mother tongue — Mandarin Chinese, Japanese, or Korean — through dedicated language programs. This multilingual approach reflects the school's diverse international community and prepares students for an increasingly interconnected world.

Assessment and Outcomes

Formal assessment at ASIS culminates in Cambridge IGCSE examinations (typically taken at age 14–16) and Cambridge AS/A-Level examinations (age 16–18). These internationally recognized qualifications provide students with credible evidence of academic achievement when applying to universities worldwide. While the school does not publicly publish detailed examination results statistics, it maintains an active Academic Achievements section and takes pride in its university placement outcomes.

A Network of Campuses

Anglo Singapore International School's three-campus structure gives it an unusual footprint among international schools in Thailand. While many international schools operate from a single location, ASIS has built a network connecting Bangkok's Sukhumvit corridor with Thailand's northeastern heartland — a structure that allows the school to serve diverse families while maintaining consistent quality and values.

Sports and Recreation

Sports facilities are a genuine strength across all ASIS campuses. The school offers 25-metre outdoor swimming pools (at both the 64 campus and Korat campus), mini pools for younger students, five-a-side football pitches with artificial turf, FIBA-standard basketball courts, badminton courts, table tennis tables, and the notably modern addition of teqball tables — a sport that combines elements of football, tennis, and table tennis to develop reflexes and coordination.

These facilities support a rich competitive sports program. ASIS offers competitive sports in football, basketball, swimming, golf, Muay Thai, badminton, and table tennis, with the philosophy that sports participation develops character, teamwork, perseverance, and sportsmanship alongside physical fitness.

Academic Facilities

In keeping with its STEM emphasis, ASIS has invested in modern science laboratories across its campuses, equipped for biology, chemistry, and physics experimentation. Computer laboratories, libraries, and interactive classrooms with electronic learning technology complete the academic infrastructure. Air-conditioned classrooms are standard across all campuses — an important practical consideration in Thailand's tropical climate.

Co-Curricular Life

Beyond the classroom and sports fields, ASIS offers a broad range of co-curricular activities (CCAs) including drama, glee/choir, singing, dance, art, handicrafts, cooking classes, Chinese Club, Japanese Club, Spelling Bee, Eco-Science Club, Junior Robotics, Debate Club, and TV Journalism. This diverse CCA menu reflects the school's commitment to developing well-rounded students with interests spanning arts, sciences, culture, and media.

Location and Accessibility

The Bangkok campuses benefit from proximity to BTS Skytrain stations — the Sukhumvit 64 campus is within walking distance of BTS Punnawithi station, while the Sukhumvit 31 campus is accessible from BTS Phrom Phong. Both locations are well-served by Bangkok's extensive taxi and rideshare networks. The Korat campus, while more remote, serves a regional community that previously had limited access to internationally accredited schooling.

An Open Door with Standards

Anglo Singapore International School presents a nuanced admissions model: deeply inclusive in its welcome to students of all nationalities and backgrounds, yet selective in ensuring academic readiness through a structured assessment process. This balance reflects the school's dual commitment to diversity and educational quality.

The Admissions Process

All applicants — regardless of grade level — are required to complete entrance assessments covering English language skills (listening, speaking, reading, and writing) and Mathematics. Additionally, prospective students participate in a trial day, spending time in actual classes to experience the ASIS learning environment and allowing teachers to observe the student in context.

This two-stage process (formal testing plus trial day) is more thorough than many international schools that rely solely on written assessments or previous school reports. It reflects ASIS's commitment to understanding the whole student, not just their academic results on paper.

Year-Round Enrollment

For expatriate families whose relocation timelines do not align with the August academic year start, ASIS accepts applications and enrolls students throughout the year. This pragmatic flexibility is particularly valuable for diplomatic, corporate, and other internationally mobile families who may receive posting notifications with little advance notice.

Scholarships and Financial Support

For high-achieving students entering the Sixth Form (Junior College level), ASIS offers a range of merit-based scholarships including the Yeap Ban Har Scholarship, academic excellence scholarships, debate scholarships, and sports scholarships. These awards may provide full or partial tuition fee remission and are open to candidates who demonstrate outstanding academic performance, exceptional extracurricular talent, and a commitment to contributing to the school community.

Documentation Requirements

While not exhaustively published, the typical admissions documentation includes previous school academic transcripts and attendance records, passport copies, and photographs — standard requirements across international schools in Thailand.

EAL Support as an Admissions Enabler

The availability of English as an Additional Language (EAL) support effectively lowers the English-language entry barrier for capable students who may not yet be fully fluent in English. This support mechanism allows ASIS to remain genuinely accessible to families from non-English-speaking backgrounds while maintaining the integrity of its English-medium curriculum.

Diverse by Design

One of Anglo Singapore International School's most distinctive characteristics is the genuine diversity of its student community. With students from more than 20 nationalities enrolled across its three campuses, ASIS creates a genuinely international learning environment that enriches classroom discussions and broadens students' cultural horizons from an early age.

Campus-by-Campus Demographics

Interestingly, each of ASIS's three campuses has a notably different demographic composition, reflecting the varied communities each serves:

Sukhumvit 31 Campus (Bangkok): The most internationally diverse campus, with approximately 70% of students holding non-Thai nationality. The international mix includes significant populations from Singapore, China (approximately 20%), Japan (approximately 5%), Korea (approximately 5%), and other nationalities, with Thai students comprising around 30% of enrollment.

Sukhumvit 64 Campus (Bangkok): More locally integrated, with approximately 80% Thai students and 20% international students (including Japanese and others). This campus serves a broader cross-section of Bangkok families who seek Singapore/Cambridge curriculum quality while living in the city's southern districts.

Nakhon Ratchasima Campus (Korat): The most locally oriented of the three campuses, with approximately 90% Thai students. As the only campus of its kind in Thailand's northeastern region, the Korat campus serves primarily Thai families who value international-quality education while remaining in their home city.

Language as Community

The school's trilingual approach — English instruction, compulsory Thai, and mother-tongue support in Mandarin Chinese, Japanese, and Korean — both reflects and reinforces this multicultural community. Language clubs (Chinese Club, Japanese Club) provide cultural spaces within the school community, while the English as Additional Language (EAL) support program ensures that students still building their English proficiency can participate fully in school life.

Inclusive Admissions

ASIS positions itself as an inclusive community, welcoming students regardless of nationality or prior educational background. The admissions process involves entrance testing and a trial day, ensuring academic readiness, but the school is committed to supporting students with diverse linguistic backgrounds through its EAL and mother-tongue programs. Applications are accepted throughout the academic year, facilitating mid-year enrollment for newly arrived expatriate families.
