Education Philosophy at Prem Tinsulanonda International School
At the heart of Prem Tinsulanonda International School lies a deeply humanistic educational philosophy articulated through its mission statement: "We are a community that challenges its members to act as compassionate, creative, knowledgeable and principled global citizens, working together for a sustainable future with continuous learning and good thinking."
This philosophy is not merely aspirational — it is operationalised through the full International Baccalaureate (IB) continuum from Early Years through Grade 12. Prem offers the IB Primary Years Programme (PYP), Middle Years Programme (MYP), Diploma Programme (DP), and — as the first school in Southeast Asia to do so — the IB Career-related Programme (CP). Each of these frameworks reinforces inquiry as the primary mode of learning, encouraging students to ask questions, make connections, and reflect critically on their role in a complex world.
Sustainability as a Core Pillar
Sustainability is woven into the school's DNA rather than treated as a standalone subject. Prem's 100-acre forested campus at the foot of Doi Suthep functions as a living classroom, with an organic farm and forest school areas providing hands-on environmental learning. Students engage with real ecological systems, growing food, studying local ecosystems, and reflecting on humanity's relationship with the natural world. This connects directly to the IB's emphasis on international-mindedness and the school's vision of students who "live sustainably."
Character Education and Core Values
Prem's four core values — Empathy, Integrity, Leadership, and Legacy — serve as pillars of the school's pastoral and academic culture. These values are deliberately chosen to shape not just academic performance but the kind of people students become. The school's vision statement captures this ambition clearly: "Prem educates global citizens who strive for excellence, live sustainably, lead responsibly, celebrate diversity, and whose integrity champions a just, more equitable and peaceful world."
Holistic Learning Beyond the Classroom
Prem's philosophy rejects a narrow definition of educational success. With over 100 co-curricular activities spanning sports, arts, service, and academic enrichment, the school provides structured space for students to discover and develop talents well beyond academic subjects. Specialist academies in Music, Golf, Tennis, and Swimming allow students to pursue excellence with professional-level coaching while remaining embedded in the school community.
The founding vision of Mom Luang Tridhosyuth Devakul — to create a school rooted in the Traidhos Three-Generation Community for Learning — reflects a belief that education is a communal responsibility extending across generations. By naming the school after General Prem Tinsulanonda, whose life embodied integrity and service, the school signals that character and contribution to society are as important as academic credentials. This ethos permeates everything from classroom culture to boarding life, creating a community where every student is challenged to grow intellectually, ethically, and personally.
From Traidhos Vision to Southeast Asia's IB Pioneer
Founded in 2001 under the Traidhos Foundation, Prem became the first school in SE Asia to offer all four IB programmes, growing into a multicultural community of 20+ nationalities.

History and Milestones of Prem Tinsulanonda International School
Founding and Origins (2001)
Prem Tinsulanonda International School was established in 2001 by Mom Luang Tridhosyuth Devakul, an architect and social entrepreneur committed to sustainable community development. The school was founded as an integral part of the Traidhos Three-Generation Community for Learning, a broader initiative designed to nurture environmental and social stewardship across age groups and communities in northern Thailand.
The school was named in honour of General Prem Tinsulanonda, Thailand's former Prime Minister and President of the Privy Council, whose life embodied integrity, public service, and principled leadership — virtues that the founders wished to instil in every student.
IB Authorisation and Pioneer Status
From the very beginning, Prem was designed as a fully IB school. The school received authorisation to offer IB programmes starting in 2002, offering PYP, MYP, and DP from its earliest years. Over time, Prem achieved a landmark distinction: it became the first school in Southeast Asia to offer the IB Career-related Programme (CP), demonstrating both innovation and a commitment to expanding pathways to success for students with diverse academic and vocational ambitions.
Campus Growth
Set on a 100-acre forested site at the foothills of Doi Suthep in Mae Rim district, Chiang Mai, Prem's campus has grown substantially over the years. Academic buildings for Early Years, Primary, and Secondary divisions are complemented by specialist facilities including a performing arts auditorium (600 seats), an outdoor amphitheatre (600 seats), an Olympic-size swimming pool, indoor gymnasium, squash courts, table tennis hall, two golf driving ranges, tennis courts, cricket pitch, and an organic farm. Boarding residences were developed to serve students from Grade 3 through Grade 12, creating a genuine residential community.
Growth of Community
From a modest start, the school has grown to approximately 555 students representing more than 20 nationalities. The teaching faculty, drawn largely from international backgrounds, numbers around 90, giving Prem one of the strongest student-to-teacher ratios in the region at approximately 6:1. This multicultural environment reflects the founders' vision of a school that transcends borders and prepares young people for a globalised world.
Recognition and Accreditation
Over its two decades of operation, Prem has earned accreditation from the Council of International Schools (CIS) and the New England Association of Schools and Colleges (NEASC), alongside its IB World School authorisation. It is also a member of the Chiang Mai Athletic Conference (CMAC) and the Mekong River International Schools Association (MRISA), anchoring it firmly in the regional international school community.
A 100-Acre Living Campus: Nature, Sport, and Community at Doi Suthep
Prem's forested 100-acre campus in Mae Rim blends world-class sports and arts facilities with organic farms, forest classrooms, and a vibrant boarding community across all grades.

Campus Life and Atmosphere at Prem Tinsulanonda International School
Setting and Environment
Prem's campus is one of its most striking features: 100 acres of forested land nestled at the foot of Doi Suthep mountain in Mae Rim district, approximately 20–30 minutes north of Chiang Mai city centre. Far from the urban bustle, the campus creates an environment where nature is ever-present — not as backdrop but as active learning environment. Students move between air-conditioned classrooms and outdoor forest classrooms, farm plots, and open athletic fields, making the physical campus an extension of the curriculum.
Academic Facilities
Academic buildings are purpose-built for each division — Early Years, Primary, and Secondary — with libraries, computer centres, and science laboratories integrated throughout. Prem holds the distinction of being an Apple Distinguished School, reflecting its commitment to technology-enhanced learning.
Arts and Performance
The performing arts are central to campus life. Two major venues serve the community: a 600-seat indoor auditorium for formal concerts, productions, and assemblies, and a 600-seat open-air amphitheatre for outdoor performances and events. A dedicated Music Academy building with practice rooms and a professional dance studio ensure that students pursuing arts have access to specialist facilities.
Sports Infrastructure
Sports facilities at Prem are exceptional for a school of its size. The campus includes an Olympic-size swimming pool (used for both training and competitive meets), a full-size indoor gymnasium, tennis courts, squash courts, table tennis hall, fitness room, multiple grass football and rugby fields, a full athletics track, two golf driving ranges, and a professional-standard cricket pitch. These facilities underpin a rigorous and varied athletics programme that competes in CMAC and MRISA conferences.
Outdoor and Experiential Learning
Uniquely, Prem's campus incorporates an organic farm and forest school area that functions as a genuine outdoor classroom. Students at all levels engage in farming, ecological study, and nature-based learning projects — a physical embodiment of the school's sustainability philosophy.
Boarding Community
Boarding is a significant dimension of Prem's campus culture. Students from Grade 3 (age 8) through Grade 12 (age 18) may board in residential apartments on campus, forming a tight-knit residential community with dedicated pastoral care. Approximately 100+ students board at any given time, creating a vibrant after-school life of sport, study, meals, and cross-cultural friendship that extends well beyond classroom hours.
Community Events
Prem International Day is an annual highlight, bringing the school's 20+ nationalities together to celebrate cultural heritage through food, music, games, and exhibitions — a vivid demonstration of the school's 'Many Cultures, One Community' ethos.
Inclusive Admissions: Open Enrolment with Support for All Linguistic Backgrounds
Prem takes a non-selective, inclusive approach to admissions, welcoming students of all English levels and backgrounds with IEP support, interviews, and grade-level assessments.

Admissions Culture at Prem Tinsulanonda International School
Open and Inclusive Philosophy
Prem Tinsulanonda International School is not academically selective in the traditional sense. The school's admissions philosophy is built on inclusion: a belief that students from diverse linguistic, cultural, and academic backgrounds all have the potential to thrive in its holistic IB environment. This stands in notable contrast to many international schools where high prior academic achievement is a prerequisite.
The Admissions Process
The process begins with an online inquiry and application form, accompanied by a non-refundable application fee of 5,000 THB. Following review, families are invited to a student and parent interview, which can be conducted either in person on campus or virtually — making Prem accessible to internationally-mobile families before relocation.
An age-appropriate academic assessment (covering English and mathematics) is also conducted to understand the student's current level and ensure appropriate placement and support. Importantly, this assessment is not used as a bar to entry but as a tool for planning individualised support.
Decisions are typically communicated within approximately 3–5 business days of the interview, making the process relatively quick and transparent.
English Language Support
One of Prem's most distinctive admissions features is its no minimum English requirement policy. The school actively welcomes students who are beginning English learners, supported by its Intensive English Programme (IEP) available to students in Grades 3 through 10. Ongoing EAL support is woven into the curriculum, enabling students from non-English backgrounds to access the full IB programme as their English develops.
Fee Structure at Admission
Beyond tuition (380,000–736,000 THB annually depending on grade), families pay a refundable security deposit of 50,000 THB (returned upon graduation or withdrawal) and a Foundation Fee (capital levy) of 130,000 THB (non-refundable, paid once). A sibling discount of 10% off tuition and boarding is available for second and subsequent enrolled children, reflecting the school's commitment to making education accessible for families.
Required Documents
Typical documentation includes previous academic reports/transcripts, identification documents, and recommendation letters. The school encourages campus visits for prospective families to experience the community before committing.
Scholarships
Three merit-based scholarship streams — Academic, Athletic, and Music — provide partial tuition support for students demonstrating exceptional talent, ensuring that financial circumstances do not prevent gifted students from joining the community.
Southeast Asia's First IB CP School: Academies, Athletics, and a Farm School
Prem uniquely combines full IB CP pioneer status, specialist academies in music/golf/tennis/swimming, a working organic farm, and one of the region's strongest student-teacher ratios at ~6:1.

What Makes Prem Tinsulanonda International School Unique
Pioneer of the IB Career-related Programme in Southeast Asia
Prem's most notable academic distinction is being the first school in Southeast Asia to authorise and offer the IB Career-related Programme (CP). While many international schools offer the IB Diploma Programme, the CP represents a different — and often overlooked — pathway that combines rigorous academic study with a professional or vocational focus. By pioneering this programme in the region, Prem has demonstrated both educational leadership and a commitment to serving students whose strengths and ambitions extend beyond the traditional academic route.
Specialist Academies
Uniquely among international schools in northern Thailand, Prem operates a portfolio of specialist Academies that offer professional-level training to enrolled students:
- Music Academy — Instruction across instruments and voice, with dedicated practice facilities
- Golf Academy — Year-round coaching using two on-campus driving ranges
- Tennis Academy — Progressive coaching programme on dedicated courts
- Swimming Academy — High-performance training using the on-campus Olympic pool
These academies blur the line between co-curricular enrichment and serious athletic/artistic development, giving students access to a standard of coaching rarely seen in school-based programmes.
Exceptional Student-to-Teacher Ratio
With approximately 555 students and 90 teaching staff, Prem operates at a student-to-teacher ratio of roughly 6:1 — significantly lower than most international schools in the region. This enables a degree of personalised attention that supports both high academic achievers and students who require additional language or learning support.
Organic Farm and Forest School
Perhaps the most unusual feature of Prem's educational environment is its working organic farm and forest school area, embedded within the campus grounds. These spaces are active learning environments where students grow food, study ecosystems, and engage with sustainability in a practical, embodied way. Rather than reading about environmental stewardship, Prem students live it — making this one of the most authentic expressions of the school's sustainability mission.
A Boarding School for Young Children
Prem accepts boarders from Grade 3 (age 8), which is notably young for a boarding programme. This allows internationally-mobile families to provide their children with continuity of education in a caring residential environment from an early age. The boarding community for over 100 students creates a genuine after-hours school life, with pastoral care woven throughout.
Connection to Thailand's National Legacy
The school's name and founding purpose connect it to Thailand's national heritage in a rare and meaningful way. Named after General Prem Tinsulanonda and founded under the Traidhos Community for Learning, the school embeds local cultural identity and values of integrity and service into a globally-oriented IB curriculum — a combination that few international schools anywhere in the world can claim.
