The British School of Bangkok Ltd. BSB British International Primary School, was established in March 1992. The School accepts children from all nationalities and believes that the diversity of the children’s experience is one of its major strengths. The school provides a British based curriculum for children aged between 2 years and 11 years.  



BSB accepts children from 2 years to 11 years old. Children are initially placed into classes according to their age on the 31st of August of the year of entry.

Class size

BSB believes that quality teaching is greatly improved when the child to teacher ratio is low giving the teacher more time to spend on small group and individual child teaching. Class sizes are kept small to ensure this. The staff to child ratio is 1:6 in the Nursery, 1:8 in Early Years, 1:9 in Reception, 1:10 in KS 1 and 1:12 in KS 2
