A family-founded school since 1992, combining the standards of a large international school with the personalised care of a small British one.
BSB British International Primary School is a family-founded school established in 1992, now a highly regarded, internationally accredited school. As a dedicated primary school, every part of BSB — our curriculum, our facilities, our teaching — is designed exclusively around the development and wellbeing of early years and primary-aged children.
Our campus is a tranquil green oasis in the heart of Bangkok on Sukhumvit Soi 4, just steps from Benjakitti Park — a safe, stimulating outdoor space families enjoy before and after school, and on weekends.
BSB is committed to nurturing the holistic development of every student, empowering them to become confident, compassionate, and innovative global citizens. We strive for excellence in all aspects of our educational practices, continuously seeking improvement to meet the evolving needs of our students in the 21st century.
Our vision is to develop global citizens and equip every student to thrive in a rapidly changing world — cultivating empathy, curiosity, creativity, and resilience, so our students become lifelong learners and proactive contributors to a diverse, interconnected global community.
A small school fosters a warm, family-like environment where children, parents, and staff build meaningful relationships.
Smaller class sizes mean every child gets individual attention and tailored support to thrive academically, socially, and emotionally.
We prioritise the whole child — academically, creatively, and morally — encouraging independence, curiosity, and higher-order thinking.
Passionate, experienced teachers adapt to the individual needs and strengths of every pupil.
A unique blend of British and Thai curricula, fostering cultural understanding for success in a globalised world.
