Lamai International School

Educational Philosophy at Lamai International School

Lamai International School (LIS) was founded on a clear and purposeful mission: "to foster the potential of every student to thrive as a global citizen." This mission permeates every aspect of school life, from curriculum design to daily classroom interactions.

Cambridge Curriculum as Foundation

Since opening in January 2016, LIS has implemented the Cambridge International Curriculum, providing students aged 3–11 with a rigorous, internationally recognised educational framework. The Cambridge approach emphasises inquiry-based learning, critical thinking, and transferable skills — preparing students not just for the next stage of schooling, but for a rapidly changing world.

Small Class Sizes and Personalised Learning

Central to the school's pedagogy is its commitment to small class sizes, with a cap of approximately 20 students per class. This results in an exceptional student-to-teacher ratio of approximately 5:1, allowing teachers to adapt instruction to "individual differences and learning styles." The school explicitly acknowledges in its vision that development-appropriate instruction must account for the varied needs of each child.

Vision: Safety, Nurture, and Academic Excellence

The school's vision statement underscores the importance of a "safe and nurturing environment" that "promotes academic excellence while creating an atmosphere of cooperation and mutual respect." This dual focus — on both emotional safety and intellectual rigour — positions LIS as a school that treats pastoral care and academic achievement as complementary, not competing, goals.

Sustainability and the UN SDGs

A distinctive feature of LIS's philosophy is the integration of the UN Sustainable Development Goals (SDGs) into the curriculum through programmes such as the LIS Green Team and the Education for Sustainable Development (ESD) Programme. Students are encouraged to see themselves as active agents of change, responsible for their environment and community. This commitment to sustainability reflects a belief that education should produce not just academically capable individuals, but conscientious global citizens.

Community and Family Culture

Beyond academics, LIS cultivates a "family-like" school community. The combination of a small student body (~500 students), a strong teacher-student relationship, and a shared commitment to community values creates an environment where every child is known and valued. This community ethos is central to why families on Koh Samui choose LIS.

History of Lamai International School

Founding (2016)

Lamai International School opened its doors in January 2016, established to bring high-quality, Cambridge-based international education to the families of Koh Samui — one of Thailand's most internationally diverse communities. The island's growing expat and tourist population created demand for a school that could offer globally recognised qualifications in an accessible, community-oriented setting.

Cambridge International from Day One

From its very first academic year, LIS implemented the Cambridge International Curriculum, distinguishing itself from local Thai schools and positioning itself as a genuine international primary school. This curriculum choice signalled the school's ambition: to prepare children not just for Thai higher education, but for schools and universities worldwide.

Growth and Community Development

Over the years since its founding, LIS has grown to serve approximately 500 students with around 100 teaching staff — a remarkable ratio that underscores the school's enduring commitment to personalised education. The school has remained focused on its founding principles: small classes (capped at ~20 students), individual attention, and a community-minded ethos.

Sustainability as a Core Theme

A significant development in LIS's institutional identity has been the deepening integration of sustainability education. Through the LIS Green Team and the Education for Sustainable Development (ESD) programme, the school has woven the UN SDGs into everyday learning, transforming the campus into a living laboratory for environmental responsibility.

Continuity of Vision

Under the leadership of Headteacher Dana Clumpus, LIS has maintained continuity with its founding vision while adapting to the evolving needs of its international community. The school continues to serve children from Foundation 1 (age 3) through Year 6 (age 11), providing the full primary educational journey within a single, cohesive institution on the island of Koh Samui.

Academic Culture at Lamai International School

Cambridge International Curriculum

At its academic core, LIS follows the Cambridge International Curriculum for the full primary phase, from Foundation 1 (age 3) through Year 6 (age 11). Cambridge Primary is designed to develop learners who are confident, responsible, reflective, innovative, and engaged — qualities that align closely with LIS's own mission to produce global citizens.

Small Classes, High Personalisation

With class sizes capped at approximately 20 students and a student-teacher ratio of roughly 5:1, LIS offers a level of individual attention that is rare in international schools of its size. Teachers are able to identify and respond to each child's learning style, pace, and interests, making differentiated instruction a practical reality rather than an aspirational policy.

Development-Appropriate Instruction

The school's philosophy explicitly emphasises "development-appropriate instruction that accounts for individual differences." This means that assessment and teaching strategies are calibrated to where each child actually is developmentally, not just where they are expected to be by age or year group. The Cambridge framework supports this through its staged progression model, which allows flexibility without sacrificing rigour.

Languages in the Curriculum

While English is the primary language of instruction (100%), Thai language is also offered as a compulsory subject — an important provision for students integrating into Thai life and for compliance with local educational regulations. This bilingual thread ensures students gain cultural fluency alongside academic skills.

Sustainability Across the Curriculum

Uniquely, LIS integrates the UN Sustainable Development Goals across subject areas, so that science, humanities, and even English lessons are connected to real-world global challenges. The Education for Sustainable Development (ESD) Programme formalises this approach, giving students structured opportunities to engage with issues such as climate change, biodiversity, and social justice from an early age.

Extracurricular Academic Support

Beyond the formal curriculum, LIS offers Extra English Lessons and a range of after-school clubs covering arts, science/robotics, chess, music, and drama. These provisions ensure that students who need additional academic support or who wish to extend their learning have clear pathways to do so.

Community at Lamai International School

An International Community in a Tropical Setting

Situated in the Maret district of Koh Samui, Thailand's second-largest island and a major international tourism and expatriate hub, LIS serves a diverse, multicultural community of families. The school's community reflects the island's cosmopolitan character, bringing together expat families, long-term residents, and local international families in a shared educational environment.

The Family-Like Culture

One of the most frequently cited qualities of LIS is its "family-like" atmosphere. With approximately 500 students spread across Foundation through Year 6, the school is large enough to offer a full primary education yet small enough for every child to be known by name. This culture of personal connection extends from the classroom to the wider school community, with parents describing a sense of genuine belonging.

The LIS Green Team: Community Through Action

The LIS Green Team is a student-led environmental initiative that has become one of the school's most visible community programmes. Students take active roles in reducing the school's environmental footprint, organising recycling drives, and advocating for sustainable practices. This initiative exemplifies LIS's belief that community is built through shared purpose and action, not just proximity.

Inclusive Approach

LIS provides EAL (English as an Additional Language) support and SEN (Special Educational Needs) support, ensuring that students who are still developing English fluency or who have additional learning needs are fully included in school life. This inclusive ethos means the community is genuinely diverse, not merely demographically so.

Daily Life: Lunch, Sports, and Clubs

The provision of daily free lunches and snacks contributes to the community atmosphere, bringing students together at mealtimes in a shared dining space. A wide range of sports (athletics, badminton, basketball, cricket, volleyball) and after-school clubs (art, music, drama, chess, science/robotics) give students multiple ways to connect with peers beyond the classroom, building friendships and community ties that complement their academic journey.

Unique Features of Lamai International School

UN SDG Integration: Education for Sustainable Development

Perhaps the most distinctive feature of LIS among international primary schools in Thailand is its systematic integration of the UN Sustainable Development Goals (SDGs) into the Cambridge curriculum. Through the formal Education for Sustainable Development (ESD) Programme, sustainability is not an add-on or an occasional project — it is woven into the fabric of daily learning across all subject areas.

Students from Foundation through Year 6 engage with real-world challenges — climate, biodiversity, inequality, clean water — through age-appropriate inquiry projects that connect their classroom learning to global realities. This approach produces students who are not just academically capable, but genuinely informed and motivated about the world they are inheriting.

The LIS Green Team

The LIS Green Team is the student-facing expression of this sustainability commitment. This initiative has "begun transforming LIS into a" more sustainable campus, with students taking ownership of environmental improvements. The Green Team develops leadership, teamwork, and civic responsibility in a way that few other primary school programmes can match.

Exceptional Student-Teacher Ratio

With a 5:1 student-teacher ratio — among the lowest possible for a school of LIS's size — every child receives an extraordinary degree of individual attention. This is a direct and tangible expression of the school's commitment to personalised learning, and it is a feature that parents of young children in particular find highly compelling.

Cambridge Curriculum in a Tropical Island Setting

LIS offers the rigour and global recognition of the Cambridge International Curriculum in the unique, relaxed setting of Koh Samui. For expat families on the island, this combination — world-class academics in a beautiful, community-oriented environment — is a key differentiator from both local Thai schools and larger, more impersonal international schools.

Free Daily Meals

The provision of free lunches and snacks for all students is an unusual and valued feature that reduces the logistical burden on families and ensures all students are nourished and ready to learn throughout the school day. This reflects the school's holistic approach to student wellbeing.

Rolling Admissions

Unlike many international schools with fixed annual intake windows, LIS operates rolling admissions throughout the year, making it accessible to families arriving on Koh Samui at any point in the academic calendar — a practical and welcoming feature for the island's transient international community.
