In Brief
Bangkok Adventist International School is a well-established American curriculum school serving 450 students from preschool through grade 12 with strong Christian values integration. Founded in 1990 by the Seventh-day Adventist Church, it offers solid academics with AP courses and impressive university placement rates at fees considerably lower than Bangkok's elite international schools.
Located on a secure 5-acre campus in the Phra Khanong area, BAIS delivers American curriculum education with WASC accreditation and a distinctly Christian foundation. The school serves a diverse community of 450 students from over 25 nationalities, with a balanced mix of Thai students (40%), Western expats (25%), and Asian families (35%). With annual high school fees ranging from $15,700-18,600, BAIS positions itself as an affordable alternative to Bangkok's premium international schools while maintaining strong academic standards through its 12:1 student-teacher ratio.
The school's facilities include modern classrooms with smart boards, science and computer labs with 1:1 device ratios from grade 6, an Olympic-size swimming pool, gymnasium, and performing arts spaces. Recent graduates achieve remarkable university placement rates of 98%, with 60% heading to U.S. universities and many receiving substantial financial aid averaging $20,000 annually. The school has expanded its AP offerings to 12 courses and recently added a sustainability wing with solar-powered laboratories, reflecting its commitment to modern educational approaches within its Adventist framework.
