Our Guiding Principles
We firmly believe that leadership is shared, and that with a common understanding of our roles, we can achieve our shared goals as a community. These guiding principles shape our approach not only as leaders, but also as learners.
- We will start with the belief that people are intelligent, capable, working hard and acting in good faith.
- We will seek to be solution-oriented, and use the school mission and a focus upon student achievement to guide discussions.
- We will advocate and support each other, and work as a team.
- We will value open discussion, aim for consensus in decisions, and constantly strive to follow up decisions and communicate effectively.
- We will strive to be transparent, make moral decisions and be fair in our dealings.
- We will create an environment based on trust and respect, which will enable our colleagues to function at their highest point of contribution.
Welcome from the Head of School
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 of a few 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 our admissions team, who can answer any questions you may have about our community. 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 that community.
James Dalziel
