Greenacre International School

Educational Philosophy at Greenacre International School

Greenacre International School's philosophy is elegantly summarised in its mission: "providing a stimulating and enriching education within a supportive, inclusive community, where each person matters and in which all students have the opportunity to thrive and fulfil their potential as a global citizen."

This mission is anchored by five core values that spell out GREEN:

• Growth — fostering continuous personal and academic progress
• Respect — encouraging mutual respect among students, staff, and families
• Environmental — embedding environmental consciousness into everyday learning
• Empathy — cultivating emotional intelligence and compassion
• Nurture — providing a caring, supportive environment for every child

These values are not merely aspirational; they are actively embedded in curriculum design, daily school life, and extracurricular programming. The school's lush 7.5-rai campus — with its environmental gardens, outdoor classrooms, and green spaces — is itself a living expression of the Environmental pillar.

Restorative Practices in Wellbeing

In line with its Empathy and Respect values, Greenacre employs restorative practices — a conflict-resolution methodology rooted in dialogue rather than punishment. This approach encourages students to reflect on their actions and their impact on others, building self-awareness and community responsibility rather than simply enforcing disciplinary rules. Staff work extended school days to support student wellbeing beyond academic instruction.

Child-Centred Learning

The school's pedagogy is firmly child-centred. Rather than a one-size-fits-all model, classrooms are tailored by age and Key Stage, with small class sizes enabling teachers to personalise learning. The integration of Cambridge International pathways with the English National Curriculum ensures that students receive both rigorous academic preparation (through structured assessment towards IGCSE) and broad, holistic development through arts, sport, and environmental projects.

This philosophy makes Greenacre particularly attractive to expatriate families seeking a nurturing, values-rich environment where academic achievement is pursued without sacrificing the wellbeing and rounded development of the whole child.

The Founding of Greenacre International School

Greenacre International School opened its doors in 2017, born from both necessity and vision. When an existing school on Koh Samui closed, the island's international community was left with a significant educational gap. Three founders — Dara Nagle, Lindsey Archbold, and Viroj Junthong — recognised this need and set about creating something new: a forward-thinking, environmentally conscious international school that would serve not only expatriate families but the broader island community.

A Campus Rooted in Nature

Rather than establishing a conventional urban school building, the founders chose a 7.5-rai plot of lush tropical land in the southern part of Koh Samui. The campus was deliberately designed to integrate natural spaces — environmental gardens, outdoor classrooms, and green areas — into the fabric of daily school life. This physical environment reflects the school's core Environmental value and supports the experiential, outdoor-oriented learning that Greenacre champions.

Building on British Foundations

The curriculum framework chosen was the English National Curriculum, supplemented by Cambridge International pathways leading to IGCSE. This gave the school immediate credibility and familiarity for British expatriate families while ensuring internationally recognised qualifications for students at age 16. The founders' decision to adopt the Cambridge IGCSE pathway also positioned GIS as a rigorous academic institution despite its relatively young age.

Growth to 418 Students

From a standing start in 2017, the school has grown to approximately 418 students — a testament to both the demand for quality international education on the island and the community's trust in the school's approach. Greenacre now stands as a recognised provider of British-style education in Koh Samui, attracting students from across the island via its school bus service that covers the main Chaweng Big C route and beyond.

Campus Life at Greenacre International School

Step onto the Greenacre campus and the first thing you notice is the greenery. The school occupies a 7.5-rai (approximately 12,000 sqm) plot in Namuang, southern Koh Samui — lush, tropical, and designed to inspire curiosity and a love of the natural world. The campus feels distinctly different from the glass-and-concrete international schools found in Bangkok or Singapore; here, the environment itself is part of the curriculum.

Facilities Designed for Rounded Development

Despite being a relatively young school, Greenacre has invested in a comprehensive range of facilities:

• Library — stocked with age-appropriate resources supporting independent reading and research
• ICT Suite — equipped for computer science, digital literacy, and programming activities
• Science Laboratory — with dedicated apparatus for hands-on experimental science
• Swimming Pool — used for both PE lessons and after-school swimming activities (with full insurance coverage)
• Sports Hall & Outdoor Grounds — supporting indoor and outdoor team sports
• Music Room — with instruments for class lessons and ensemble practice
• Drama / Performing Arts Space — for school productions and creative expression
• Art Room — for visual arts and design technology
• Environmental Gardens & Outdoor Classrooms — enabling nature-based learning
• Cafeteria — providing affordable school lunches (approximately 50 THB per meal), with packed lunches also permitted

The Daily Rhythm

School begins at 8:40 AM and concludes at 3:00 PM. All students wear uniform — with separate uniforms for everyday wear, PE, and swimming — reinforcing a sense of community and equality. After school, a wide array of clubs runs until the late afternoon, with the school bus service collecting students from the Chaweng area on the return journey.

A Nurturing, Inclusive Atmosphere

The atmosphere at Greenacre is described as inclusive and community-oriented. With approximately 418 students spread across Kindergarten through Grade 9 (ages 3–16), the school is small enough that every child is known by name. The restorative practices approach to discipline means that conflicts are handled through dialogue rather than exclusion, and the extended presence of staff throughout the school day ensures consistent pastoral support.

Academic Culture at Greenacre International School

Greenacre International School delivers a British National Curriculum education, augmented by Cambridge International pathways that culminate in the IGCSE examinations at Key Stage 4 (Grades 9–10, approximately ages 14–16). The school is recognised as a Cambridge examination centre, and the Edexcel examination system is also referenced in third-party sources.

Key Stages and Structure

The academic journey at Greenacre follows the British Key Stage model:

• Early Years / Kindergarten (ages 3–5): Foundation stage focusing on play-based learning, language development, and early numeracy
• Key Stage 1–2 / Grades 1–6 (ages 5–11): Core subjects including English, Mathematics, Science, Humanities, Art, Music, PE, and Thai language
• Key Stage 3 / Lower Secondary (Grades 7–9, ages 11–14): Subject specialisation begins, with students studying English, Mathematics, Sciences (Chemistry, Biology, Physics), Humanities (History, Geography), Arts, ICT, Drama, Design & Technology, and Thai
• Key Stage 4 / IGCSE (Grades 9–10, ages 14–16): Cambridge IGCSE examinations in core and optional subjects, including English, Mathematics, Sciences, Humanities, Thai (as first or second language), and Arts/PE electives

EAL and Academic Support

The school explicitly acknowledges the challenges faced by students whose first language is not English and provides EAL (English as an Additional Language) support through experienced classroom teachers. The Secondary team in particular is described as helping students "engage fully in the curriculum" regardless of English background.

What Comes After?

It is important for prospective families to understand that Greenacre currently educates students up to Grade 9 / age 16 only. There is no Sixth Form, A-Level, or IB Diploma programme. Families seeking education beyond IGCSE will need to transition to another school. This is a common pathway for international families on Koh Samui who move their children to Bangkok, the UK, or another international school for the final two years of secondary education.

Small Class Sizes

One of Greenacre's most frequently cited advantages is its small class sizes, which enable greater individual attention and differentiated instruction — a significant benefit in a school serving children from diverse linguistic and cultural backgrounds.

Community and Extracurricular Life at Greenacre International School

Greenacre's approach to education extends well beyond classroom walls. The school places enormous value on the development of the whole child — socially, creatively, physically, and ethically — and this is reflected in the breadth and character of its extracurricular programme.

After-School Clubs

Greenacre's after-school clubs span a wide range of interests and abilities, from competitive sports to creative arts to community service:

• Mixed Martial Arts — open to all year groups, developing discipline and physical fitness
• Chess Club — fostering strategic thinking and healthy competition
• Environmental Club — engaging students in conservation projects on the island
• Creative Thai — exploring Thai language, culture, and traditions
• Art Club — painting, sculpture, and mixed-media creation
• Music and Choir — instrumental tuition and ensemble singing
• Drama Club — culminating in school productions that are a highlight of the school calendar
• Duke of Edinburgh Award — the internationally recognised leadership and service programme
• Community Service — volunteer work and fundraising in and around Koh Samui
• House Competitions — inter-house sporting events and team challenges

Environmental Commitment

The school's Environmental core value translates directly into action. The campus gardens are used as living classrooms, and the Environmental Club connects students with real conservation challenges on the island. Field trips to local natural sites further reinforce this connection to the Thai natural environment.

The School as Community Hub

Greenacre describes itself as an inclusive community where each person matters — and this ethos is evident in how the school relates to families and the wider Koh Samui community. The affordable school bus service ensures that families from across the island can access the school, and the competitive low-priced cafeteria makes school lunches accessible to all. The school's parent community is actively engaged, and the relatively small size of the school (around 418 students) means that relationships between families, teachers, and students are close and meaningful.
