“A Warm Welcome to Siam International School”
“Welcome to Siam International School! We are proud to offer a nurturing environment where students from all over the world come together to learn, grow, and thrive.”
Brief Overview of the School
Siam International School, established in 2003, has been under its current management since 2012. Located in Thanyaburi, Pathum Thani, Thailand, we offer a world-class education for students from Pre-Kindergarten to Year 13, following the British curriculum. Our mission is to empower students to reach their full academic and personal potential within a nurturing and supportive environment. We are committed to fostering a culture of excellence, creativity, and global citizenship.
Who We Are
At Siam International School, we are a dynamic and inclusive community committed to shaping the next generation of global citizens. Our school is not just a place of academic learning but a nurturing environment where students are encouraged to grow holistically, both in their academic pursuits and personal development.
We believe in empowering students with the values and skills they need to succeed in a rapidly changing world. Guided by our core principles—Sustainability, Citizenship, Imagination, Aspiration, and Mentorship—we foster an atmosphere that encourages lifelong learning, creative thinking, and compassionate action.
Sustainability
We instill a deep understanding of the importance of environmental and social sustainability. Our students are encouraged to engage with the challenges facing our world today and become active participants in building a more sustainable future. Whether through curriculum initiatives, eco-friendly projects, or community service, sustainability is embedded in every aspect of our school culture.
Citizenship & Responsibility
We teach our students the importance of being active citizens who are responsible, compassionate, and engaged members of society. At SIS, we emphasize the value of responsibility—not only toward the environment but also toward the well-being of our local and global communities. Our students are encouraged to contribute meaningfully to society and become thoughtful, empathetic individuals who understand the value of service and social justice.
Imagination
Imagination is the cornerstone of creativity, and at SIS, we cultivate an environment that encourages creativity, originality, and critical thinking. Our curriculum and extracurricular activities are designed to inspire students to think beyond the ordinary, exploring new ideas and solving problems in innovative ways. We nurture curiosity and push boundaries, allowing our students to imagine a better world and work toward bringing that vision to life.
Aspiration
We believe that aspiration is key to achieving success. At SIS, students are encouraged to set goals, develop ambition, and pursue entrepreneurship. Whether it's academic achievement or personal development, we support our students in reaching their highest potential. Our approach to education helps students discover their passions, build resilience, and achieve greatness, both inside and outside the classroom.
Mentorship
Our educators are not just teachers—they are mentors who guide students toward personal and academic success. We foster leadership, social skills, and collaboration, equipping students with the tools they need to succeed in today’s complex world. Through mentorship, we empower students to become leaders who can inspire and collaborate with others to create positive change in their communities and beyond.
