BASIS International School Bangkok

The school’s mission is to educate students to the highest international levels using a spiraling liberal arts and sciences curriculum benchmarked against top global education systems. It fosters a joyful learning culture that celebrates hard work and intellectual pursuit, aiming to develop students' critical thinking, creativity, and problem-solving skills.

The school offers a comprehensive K-12 program: Early Years (Pre-K to Kindergarten) focuses on literacy and numeracy; Primary Years (Grades 1-3) emphasizes core subjects and "Connections" projects; Bridge Years (Grades 4-5) transitions students to abstract thinking; Middle School (Grades 6-8) provides a rigorous schedule including physics, chemistry, biology, economics, and logic; and High School (Grades 9-12) offers university-level content and Advanced Placement (AP) courses. An optional Chinese Language Program and a Thai Language and Culture Program are also integrated into the curriculum.

Graduates of the BASIS network consistently gain admission to top colleges and universities worldwide. The school reports that 100% of its graduates are accepted to one or more universities, with students frequently earning AP Scholar recognition and significant scholarship awards.

The school employs a two-teacher model in classrooms, featuring both Subject Expert Teachers (SETs) and Learning Expert Teachers (LETs) to provide individualized support and guidance. Teachers are required to reserve a minimum of two hours per week for after-school student support.

The school maintains a selective, multi-step admissions process for students from Nursery to Grade 12. Prospective families are encouraged to attend campus tours and admissions events, and the school provides a referral program and sibling discounts to support enrollment. Interested families may join an interest list to receive updates on deadlines, events, and application requirements.

The school operates on an academic calendar that typically spans from August to the following year. Specific dates for the 2025-2026 academic year are available through the school's official calendar resources.
