Harrow International School, Bangkok is one of two schools licensed by the Harrow Foundation. It is a Kindergarten-Year 13 Independent School which follows a traditional British curriculum.

A Harrow education is a broad one, enabling pupils to fulfil their academic potential and enjoy many activities outside the classroom. The school is situated on a spacious campus in Don Muang and the facilities are excellent, including those for boarding. The teaching staff are primarily from the UK and very well qualified; many of them live on site which underpins the strong sense of community within the school.
