Bilingual Inquiry: Windfield's Child-Centered Learning Philosophy
Windfield places inquiry-based, bilingual education at its core, immersing children in English, French, and Thai cultures to develop globally minded graduates.

Educational Philosophy at Windfield International School
Windfield International School's philosophy is built on a clear conviction: that children thrive when learning is joyful, purposeful, and immersed in language and culture. The school's official mission — "We seek to inspire children to become global citizens through an inquiry-based learning environment, immersed in multiple languages and cultures" — encapsulates this approach with directness.
Inquiry-Based Learning
At its heart, Windfield's pedagogy is inquiry-based. Rather than rote memorisation, students are encouraged to ask questions, investigate, and construct their own understanding. This aligns the school with progressive international education models used by the Cambridge and French national systems, both of which reward analytical thinking and applied reasoning.
The child is positioned at the centre of the learning experience, with teachers acting as facilitators rather than mere content deliverers. This is especially evident at the Chiang Mai campus, where mixed-age classes allow older students to model curiosity and younger ones to aspire upward — a deliberate design choice that mirrors Montessori and Reggio-influenced pedagogies.
Bilingual and Multilingual Immersion
Windfield's most distinctive philosophical pillar is its commitment to genuine bilingualism. English and French are both full languages of instruction, not simply subjects. From the earliest years, students are immersed in both linguistic streams simultaneously, developing what the school calls "language fluency and cultural intelligence."
Beyond English and French, Thai is introduced from age 2, and Spanish and Chinese are offered as students progress. This multilingual scaffolding is not merely practical — it reflects a belief that language shapes cognition and empathy, and that a child who navigates multiple linguistic worlds is better prepared for the complexity of the 21st century.
Core Values in Practice
Windfield identifies five core values that translate philosophy into daily school life:
- Global Citizenship — students engage with global issues and local community service
- Language & Cultural Fluency — bilingual instruction and multicultural community
- Academic Excellence through Inquiry — rigorous but student-led learning
- Innovation & Future-Readiness — preparing students for a changing world
- Responsibility & Reflection — character development and self-awareness
These values are visible in the school's co-curricular design: from community service clubs and dance to STEM exploration and student council, every activity is framed as an opportunity for character growth, not just skill acquisition.
Balancing Tradition and Modernity
The school consciously integrates Thai cultural traditions alongside French and British educational heritage. This is not superficial — the Chiang Mai campus is located on land historically connected to France's educational presence in Thailand, and the curriculum deliberately weaves in Thai language, arts, and cultural awareness as non-negotiable components. The result is an institution that respects its hosts while offering a world-class international education.
From a French School on Koh Samui to a Two-Campus International Network
Windfield grew from the French School of Koh Samui into a dual-campus bilingual institution, opening its Chiang Mai campus in September 2024 as the city's first French-curriculum international school.

The History of Windfield International School
Origins: The French School of Koh Samui
Windfield International School traces its roots to the French School of Koh Samui, a small French-language international institution catering to the expatriate community on Thailand's popular island. The school was directed by M. Stéphane Salaun, a French educator who recognised both the demand for quality bilingual education in Thailand and the opportunity to scale that vision into something larger.
The founding partnership brought together Salaun's educational expertise and the resources and local knowledge of the Yongsiri family, a Thai family with deep ties to the region and a shared passion for education. This Franco-Thai collaboration became the institutional DNA of what would become Windfield International School.
Expansion to Two Curricula
As the Koh Samui campus evolved, the school formalised its relationship with two prestigious international educational bodies:
- Cambridge Assessment International Education (CAIE) — enabling the school to offer the British curriculum pathway including IGCSE and A-Levels
- AEFE (Agence pour l'Enseignement Français à l'Étranger) — the French Ministry of Education's global network, giving Windfield official French international school status
This dual accreditation transformed Windfield from a single-language community school into a genuinely bilingual institution with pathways to both British and French university entrance qualifications.
The Chiang Mai Chapter: 2024
The most significant milestone in Windfield's recent history was the opening of its Chiang Mai campus on 2 September 2024. Located at 288 Charoen Rat Road in the Wat Ket neighbourhood, the campus occupies land with a historic connection to France — a plot long associated with France's cultural and educational footprint in northern Thailand.
The campus launched modestly: 8 students of 5 nationalities, 12 staff members including 3 teachers. But its significance was outsized: Windfield Chiang Mai became the first and only French-curriculum international school in Chiang Mai, filling a gap that had long existed in the city's international education landscape.
French Embassy Recognition: 2025
In 2025, a delegation from the French Embassy in Thailand visited the Chiang Mai campus, an endorsement that underscored Windfield's standing within France's global educational network. The visit was covered by Chiang Mai Citylife, cementing the school's profile in the regional press.
Windfield's trajectory — from a single island school to a two-campus bilingual institution with diplomatic recognition — reflects both the growing demand for international education in Thailand and the founders' ambition to build something durable and distinctive.
Dual Curriculum Excellence: Cambridge and French Bac Under One Roof
Windfield uniquely offers both the Cambridge British pathway (IGCSE, A-Level) and the French National curriculum (AEFE), preparing students for universities worldwide in a small-class bilingual environment.

Academic Culture at Windfield International School
A Rare Dual-Curriculum Model
Few international schools outside Europe offer genuine parallel British and French curriculum tracks under one roof. Windfield does. Students can follow the Cambridge Assessment International Education pathway — moving through Cambridge Primary, Lower Secondary, IGCSE, and A-Levels — or the French National Curriculum as an AEFE-affiliated school, progressing through Maternelle, Primaire, Collège, and ultimately the Baccalauréat.
This is not a hybrid or watered-down version of either system. Windfield holds official affiliations with both bodies, meaning its qualifications are recognised by universities in the UK, France, and internationally.
Bilingual Instruction from Early Years
Academic life begins bilingually from age 2. English and French are both used as languages of instruction — not simply taught as subjects — creating an immersive environment that linguists and educators recognise as the most effective path to genuine bilingual competency. Thai is introduced from the earliest years, and Spanish and Chinese are available as students progress.
For non-native speakers of either English or French, the school provides dedicated EAL (English as an Additional Language) support and tailored English intervention classes, ensuring that language gaps do not become barriers to academic achievement.
Small Classes, High Attention
Windfield's classes are described as small and multicultural. At the Chiang Mai campus, mixed-age groupings mean that each child receives a high degree of individual attention. The Chiang Mai launch ratio of 8 students to 3 teachers (approximately 2.7:1) is exceptional by any measure, though this will change as enrolment grows.
The Koh Samui campus, which has been operating longer, offers a more established setting with specialist subject teachers and dedicated learning support staff.
Assessment and Qualifications
Students are prepared for:
- Cambridge IGCSE (typically at age 16)
- Cambridge A-Levels (age 18, UK university gateway)
- French Baccalauréat (age 18, French and international university gateway)
This dual-exit qualification structure is particularly valuable for families with international mobility — a child can begin their education on the French track and transition to the British track (or vice versa) without losing academic continuity.
Pedagogy in Practice
The school's inquiry-based approach means that even within the structured Cambridge and French curricula, teaching prioritises understanding over memorisation. Students are encouraged to investigate, debate, and apply knowledge to real-world contexts — skills that serve them whether they proceed to French grandes écoles or British Russell Group universities.
A Multicultural Franco-Thai Community at the Heart of Windfield
Windfield cultivates a tight-knit multicultural community blending French, British, Thai, and international families, with strong pastoral care and a broad co-curricular programme.

Community Life at Windfield International School
Who Makes Up the Windfield Community?
Windfield's community is genuinely multicultural. At the Chiang Mai campus opening, students of 5 nationalities enrolled in the inaugural cohort of just 8 pupils — a microcosm of the diverse international community the school seeks to build. The school draws primarily from expatriate families (French, British, and other nationalities) living in Thailand, as well as Thai families who value bilingual education for their children.
The founding partnership between a French educator (Stéphane Salaun) and a Thai family (the Yongsiri family) is itself symbolic of the school's identity: not a transplanted European institution, but a genuinely Franco-Thai creation that belongs to its host country while offering world-class international credentials.
Pastoral Care and Wellbeing
The school takes a holistic view of student wellbeing. At the Koh Samui campus, the following pastoral services are explicitly listed:
- Student counselling — professional pastoral support
- Dedicated learning support — for students who need additional academic assistance
- EAL intervention — for students developing English or French proficiency
- School nurse — (not explicitly confirmed, though support services are described)
The school's emphasis on character development — expressed through community service, reflection, and responsibility as core values — suggests that pastoral culture is woven into the academic programme rather than bolted on.
Co-Curricular Life
Despite being a relatively small school, Windfield offers a broad co-curricular programme spanning:
- Sports: Basketball (inter-school competitive), swimming, yoga/wellness
- Arts: Art club, dance, drama, music ensemble, choir
- Languages & Culture: French Culture Club, Thai Culture Club, Spanish Club, Chinese Club
- Service & Leadership: Community Service Club, Student Council
- STEM: Science Club, Robotics & Coding, Environmental Club, Math Club
- Character Development: Duke of Edinburgh Award Scheme
The inter-school basketball competition with ISS (International School Samui) indicates that even at this scale, Windfield participates in the broader international school sporting community — an important signal for families who want their children to compete and connect beyond campus.
Parent Partnership
The school's admissions language emphasises a welcoming, caring environment, and the relatively small scale of both campuses means that parent-school relationships tend to be direct and personal. The school communicates in both English and French, making it accessible to both language communities within the parent body.
The Broader Thai Context
Windfield consciously integrates Thai culture into its community life. Thai language is taught from age 2, and the school positions itself as a bridge between international and Thai educational traditions — not a bubble insulated from its host country, but an institution that celebrates and learns from Thailand while offering pathways to the world beyond.
Thailand's First French-Curriculum School in Chiang Mai — and a Dual British/French Model Unique in the Region
Windfield is the only AEFE-affiliated French-curriculum international school in Chiang Mai, and one of very few schools globally offering both Cambridge and French Bac pathways in a bilingual setting.

What Makes Windfield Unique
The Only French-Curriculum School in Chiang Mai
When Windfield opened its Chiang Mai campus in September 2024, it created something genuinely new: the first and only French-curriculum international school in Chiang Mai. For the French expatriate community — and for any family seeking a French-language educational pathway in northern Thailand — this was a landmark development.
The significance extends beyond the French community. AEFE accreditation means Windfield's French Bac is recognised globally, opening doors to universities in France, Belgium, Switzerland, Canada, and beyond. For families rotating through international postings, a school that issues AEFE-recognised diplomas is not merely convenient — it is often essential for educational continuity.
A Genuinely Dual-Track Curriculum
Windfield's second distinctive feature is the coexistence of two complete international curricula:
- Cambridge International (CAIE) — from Cambridge Primary through IGCSE and A-Levels
- French National Curriculum (AEFE) — from Maternelle through the Baccalauréat
This is not a marketing statement — it reflects formal accreditation from both bodies. Most international schools choose one curriculum system. Windfield's dual-track model means families have genuine choice, and children with mixed Franco-British educational histories can be accommodated without disruption.
Multilingual from Age Two
Very few international schools offer five languages of instruction or study from early childhood. At Windfield:
- English and French are both instructional languages from age 2
- Thai is introduced from age 2
- Spanish and Chinese are offered as students progress
This multilingual environment is a significant differentiator for families who value linguistic capital as a long-term investment in their children's futures.
A Franco-Thai Founding Partnership
Unlike many international schools in Thailand that are founded by foreign corporations or individual foreign educators, Windfield was created through a genuine Franco-Thai partnership — French educational expertise combined with Thai family investment and local knowledge. This is reflected in the school's DNA: it integrates Thai culture and language into its curriculum rather than treating Thailand as merely a geographic backdrop.
Intimate Scale with Ambition
The Chiang Mai campus opened with 8 students — a scale that might appear modest but which has significant advantages: every child is known personally by every teacher, mixed-age classes allow peer mentoring, and the school can adapt rapidly to the needs of individual learners. This intimate scale, combined with the credibility of dual international accreditation, positions Windfield as a boutique alternative to larger, more anonymous international schools in the region.

History
Windfield International School was established through a partnership between Stéphane Salaun, then Director of the French School of Koh Samui, and the Thai Yongsiri family, driven by a shared passion for education. The Koh Samui campus evolved from the French School of Koh Samui.
