KBV was set up in 1944 soon after the death of Mrs. Kasturba Gandhi, wife of Mahatma Gandhi by Harijan Sewak Sangh(HSS).
It was started on a plot of land of 2.5 acres donated by Shri Manmohan Dhar in Ishwar Nagar on main Mathura Road in South Delhi. Its initial funding was provided by prominent philanthropists who were close to Gandhiji and his ideals. The objective was to provide quality education to girls from underprivileged families. Mrs. Rameshwari Nehru worked as Manager of the school during its first 20 years.
It is said that Gandhiji himself was present in the school when it was opened on 2nd April 1944 by Shri C.Rajagopalachari who later became the first Governor General of India. KBV is a girls senior secondary school. As of 2020, it has about 900 girl students out of which about 170 live in the hostel which is only meant for scheduled caste (SC) girls. The school has classes from KG to 12th. It is affiliated to CBSE and is a Government aided school, which means that 95% of the salaries of teachers and other staff are paid by the Government of Delhi.
The school has Arts and Commerce stream in 11 and 12 classes. There is not much demand for science among the girls who typically join our school. Primary classes were started only in 2016.
