The school was founded in 1964 by the
Bharat Heavy Electricals Limited company to provide education for the children of the company's employees. Subsequently, the school opened admissions for non-BHEL students too. Initially, the school was given the name Boiler Plant Higher Secondary School, and was renamed to be R.S.Krishnan Higher Secondary School, in memory of the first executive director of BHEL. It was run by the
Montfort Brothers of St. Gabriel until 2006, when the
Singapore-based Global Indian Education Foundation took over the management of the school. R.S.K. was under their preview for a tenure of 5 academic years. From June 2011 to May 2016 the School was managed by Dr. K.K.R's Gowtham Concept Schools, a pioneer group of Educational Society from Andhra Pradesh. During September 2016, Pavai Varam Educational Trust took over the school's management and from 2021 it is being managed by the DAV Group of schools, Chennai, and had been running the school successfully ever since. == Infrastructure ==
