In August 1997 a pre-school called Tiny Tots was established in a villa on Nguyen Van Thu Street in District 1. Starting with only two classes, two overseas teachers and 40 toddlers, Tiny Tots quickly became the pre-school of choice for expatriates living in Ho Chi Minh City. Building on this success a second pre-school called Fundino was quickly established in District 3.

The original Tiny Tots villa was extended in 2000 to accommodate an additional 10 primary classrooms bringing the total school roll to 300 children. This was the first year the school was officially called The British International School, with Ms Marjorie Hunt being the first Head Teacher.

Two years later a new Primary campus was built in the residential An Phu area of the city. Mr Alun Thomas was appointed as Principal of the three campuses and enrolment jumped to 600 children. In August of 2005 a purpose built Secondary campus was opened on land close to the new Primary campus in An Phu. The number of students on roll had now risen to almost 1,000.

In August 2007 another new primary school was built on Tu Xuong Street in District 3, combining the Nguyen Van Thu campus and the Fundino campus into one new school. Mr Shaun Williams was appointed as Principal and the school roll had risen to 1,350 children aged 2 – 18.

In August 2008 an extension to the An Phu Primary campus was opened followed by an extension to the An Phu Secondary campus in August 2010. These extensions provided additional classrooms and specialist facilities allowing the school to grow towards its projected target of 2,000 students.

As the school grows from strength to strength it is now the school of choice in Ho Chi Minh City and is recognized as one of the leading international schools in the region.
