Our history

The Founding Orientation

NIVA considers every student a unique gift from God and all students are treated equally irrespective of their age, gender, race, nationality, and religion. NIVA provides a high standard of holistic education that develops the intellectual, social, physical, emotional and spiritual faculties to the optimum. 


NIVA was first established in September 1991 as a private non-church affiliated Seventh-day Adventist (SDA) Christian school named NIVA Overseas School (NOS). There were only six international schools in Thailand at that time. NOS restricted its admissions to international students and overseas Thai students. In August 1997, NIVA extended its operation by opening NIVA International Kindergarten (NIK). Five years later, in 2002, NOS and NIK were merged and relocated to the present site as NIVA International School. In 2018 after providing American-based education for fifteen years, the school was rebranded and the name was changed to NIVA American International School  


The name “NIVA” was coined from the first two letters of Nicholas and Vanisara, the children of the school’s founders. The current meaning of “NIVA” stands for Nurturing, Innovative, Virtuous, and Achieving: the hallmarks of NIVA American International School.
