Head of School's Welcome

Head of School's Welcome

It is with great pleasure that I welcome you and your family to NIST International School. NIST is unique in Thailand, being the first full International Baccalaureate World School to offer the Primary Years, Middle Years and Diploma Programmes. Initially established through efforts by United Nations families, NIST remains one of the few not-for-profit international schools in the country with strong ties to the diplomatic community.

Although our rigorous academic standards and performance often receive the most attention, we feel that the NIST programme provides a comprehensive and globally focused education for all of our students. Our school is a celebration of diversity, innovation and continuous growth. Our heritage is one of a multicultural, multinational and multilingual community. We have continued to develop our facilities to support new thinking, especially in the areas of science, technology and social entrepreneurship. We are primarily a community of learners who support the pursuit of individual excellence while also exploring ways that we might enrich the lives and experiences of others.

We encourage you to browse our website and speak to one of our Admissions team who will answer any questions you may have about our school. Every school bases its success on the collaborative efforts of teachers and parents and we are fortunate to have a community of caring parents to help support us as we aim to provide the best possible education to every student in our care. I hope that you and your family will consider joining our community.
