The school was welcomed its first set of students on 2 July 1978. The school celebrated its Golden Jubilee (50 years) on 1 November 1991. Though originally a Gujarati medium school, in June 1987 the school decided to convert the medium of instruction to English.

Before 1993 it was situated at different locations and the growing demand for admission began to strain facilities. It was, therefore, decided to shift the school to a larger building that would offer better facilities in terms of a large playground, spacious classrooms, laboratories, a hall, and adequate administrative space.

In 1992, it was upgraded to secondary level. An application for a composite affiliation was made in the academic year 1992–93. The rented premises of the school and its plans for a school building were inspected in November 1992 and the school was granted composite affiliation until Grade X for 1993 (see CBSE letter reference number CBSE/Aff/91/61304, dated 22-12-1992). The first batch of Class X students appeared at the AISS Examination of the CBSE in March 1996. It was upgraded to Senior Secondary School in 1999 and the first batch of Class XII students appeared at the Board examination in 2001.

The current school building was constructed in 1992–93 and occupied in the beginning of the following academic year. As it is located in an area called Al Wadi Al Kabir, Indian School Muttrah as it was called from 1987, was renamed Indian School Al Wadi Al Kabir as per the instructions of the Directorate of the Ministry of Education. This building has science laboratories, IT laboratories, two libraries, an art room, a music room, a multi-purpose hall with facilities for indoor games, and space for outdoor games.

By the time the school moved to the new premises in Wadi Kabir, the number enrolled had increased and an afternoon shift was introduced on the same premises. However, because the two-shift system was very inconvenient to parents and students, it was abolished and pre-primary and some of the primary classes were shifted to rented premises. At the same time plans were being prepared for a new building in Wadi Kabir, which was ready in July 2000. It houses Kindergarten and Classes I to V. The primary grounds have been extended to accommodate larger crowds for events. In 2008, two more floors were added to the senior school. By 2015-16 every classroom was equipped with smart boards and projectors and in December 2015 construction was started in the senior school to add more class rooms. Pre-primary classes had already been housed in premises very close to the building in 1997. In 2018 elevators were installed in every floor for easy movement of students and teachers. the principal of the school was Mr.Lobo from 1990 to 2008 the current principal joined Mr D.N Rao in 2012.

In November 2024, Indian School Al Wadi Al Kabir (ISWK) established its first international partnership with StockGro, an Indian financial education platform. This collaboration aims to enhance financial literacy among students through various initiatives, including a virtual stock market competition designed to educate participants about stock trading and investment strategies.
