ISD is part of STS Educational Group Limited

In 1998, the STS Group decided to diversify into the supply of educational and medical services and consequently set up subsidiaries. It acquired land in Bashundhara; a site in the northeast quadrant of the city. Bashundhara is a short drive from the main residential and diplomatic areas of Baridhara and Gulshan.

In 1998, construction of the school began on a 5.5 acres plot and was completed during the course of the 1999-2000 school year, when the first classes from Nursery to Grade 5 were admitted.

Today the school fully occupies a rich landscape with classroom space for Nursery (aged 3-4 years) to Grade 12 students. The facilities include a swimming pool, gymnasium, sports field, cafeteria, fully-equipped theatre with seating for 360, science laboratories, computer suites and a purpose-built library.

The International School Dhaka (ISD) was granted NEASC accreditation on 4th November 2004 and CIS accreditation on 25th November 2004.
