As the founder of Prem Tinsulanonda International School, I am delighted to welcome you to our vibrant community of learners, where we provide an education that fosters creativity, sustainability, and community engagement.

At Prem, we believe in providing our students with an education that inspires and challenges them to become compassionate, knowledgeable global citizens. Our stunning natural campus and commitment to engendering 'good thinking' encourages our students to think critically, communicate effectively, and develop leadership skills that enable them to succeed in a rapidly changing world.

We take great pride in being an integral part of the Traidhos Three-Generation Community for Learning and embracing our shared vision for sustainable education and community engagement. Together, we work towards a common goal of creating a better world by fostering creativity, environmental stewardship, and social responsibility.

Through our ongoing work with Traidhos, we offer our students unique opportunities to engage with the world around them, ensuring that our students develop a deep understanding of environmental and cultural diversity, and acquire the skills and knowledge necessary to become change-makers in their communities.

At Prem, we firmly believe that education is a partnership between families and our school, and we work tirelessly to ensure that our students thrive academically, socially, and emotionally. We are excited to welcome you and your family to our community, where we can continue to learn, grow, and make a difference together.

It is my pleasure to welcome you to a virtual tour of Prem Tinsulanonda International School, or simply Prem, as it is best known. If you are looking for a stimulating, engaging environment where your children will flourish daily, find their passions, and fulfill their potential, then you have found the right place.

The majority of students at Prem follow the academically rigorous IB programme; typical of its innovative spirit, Prem was the first school in South East Asia to offer all four IB programmes – The Primary Years Programme (PYP), Middle Years Programme (MYP), Diploma Programme (DP) and the Careers-related Programme (CP). 

The IB facilitates an approach to learning which has enquiry, critical-thinking and problem-solving at its heart; it also requires students to bring their heart to class. Curriculum content presents real-world global issues and students continually engage with subject matter that requires intercultural understanding.

Students at Prem are similarly challenged and engaged by the amazing co-curricular programme here. ‘Exploria’ does as the name suggests: allows students to explore a rich range of offerings from over 100 sports and activities. Most of these take place on the beautiful 100-acre campus, complete with its own farm, award winning Artist Residency Programme, Forest School, Cookery School, olympic-sized swimming pool, golf-driving range and even an ICC-approved cricket-pitch. Prem offers the most stimulating of learning environments – and one which is most appreciated by our 80 plus boarders who are proud to call Prem their home.

We invite you to come and visit us and see for yourself this unique learning centre. Prem is an exceptionally special school and one that offers the very best in personalised learning, individual support and pathways that allow students to succeed at the very highest levels.

We look forward to your visit.
