NIST International School in Bangkok is a not-for-profit IB World School offering the full International Baccalaureate curriculum (PYP, MYP, DP) from ages 3 to 18. Founded in 1992 with support from the United Nations, NIST serves over 1,800 students from 50+ nationalities. In August 2025, NIST completed Phase 2 of its campus development. This expansion introduced a Pavilion Building featuring a Lecture Hall, meeting rooms, and The Lounge. It also added two Elementary Buildings that nearly double previous spaces. These specific additions include a two-level Elementary Library, a Learning Kitchen, a Science Lab, an Elementary Gymnasium, and three Makerspace areas. Link bridges now connect these new structures with the Innovation and Creative Arts Buildings to ensure accessible movement across the school. NIST is distinctly known for its Global Citizen Diploma, a signature initiative offered alongside the IB curriculum. As part of an eleven-school consortium, this programme allows secondary students to formally document their values, qualitative learning experiences, and community service beyond standard report cards.
