Qualities and characteristics best defining the school

The first and only full, not-for-profit International Baccalaureate (IB) international school in Bangkok, Thailand, NIST International School was established in 1992 with the support of the United Nations. The school now welcomes over 1,700 students who represent more than 60 nationalities, and provides all three IB programmes. Governed by the parent-elected NIST International School Foundation, our community shares a singular goal, encapsulated in our mission: NIST inspires growth, empowers individual excellence and enriches lives.

Teaching approach of the school

The IB permeates our philosophy and approach at all levels, and we are recognized as one of the best IB schools in the world. From the early years, in which play and exploration play central roles in developing inquiry as a skill, to the Diploma Programme, in which students direct their own learning and adopt a growth mindset, we cultivate learners who are reflective, passionate and caring.
