SISB is a leading provider and manager of Singapore International Schools in Thailand. Founded in 2001, SISB currently owns and manages four campuses, which adopt the Singapore and UK curricula as the foundation for teaching and learning. The SISB name is inspired by its first campus, Singapore International School of Bangkok, which pioneered the Singapore education curriculum in Thailand.

All campuses provide a standardised curriculum underscored by the twin principles of the Singapore education system and consistently deliver high-quality education that many have come to trust from SISB. Through a broad-based and unique multi-lingual curriculum, SISB fosters students as lifelong learners and future leaders. With more than 1,000 students of over 20 nationalities and strong teaching and support staff from over 20 countries, the SISB community is inspired by a global outlook and enriched by cultural diversity.
