Previously known as Little Star School, the foundation of SIS, Ranchi was laid in 1980 by Mrs Kabita Das Roy with the sole intention of serving the society. She believed that children were the future and their empowerment would lead to progress. The school is a co-educational English medium Senior Secondary school affiliated to Central Board of Secondary Education (CBSE) under All India 10+2 pattern in both science and commerce streams.
The school was built with the sole purpose of bringing the marginalized and underprivileged at par with rest of the society by providing them with an environment and facilities that would induce progress in these children. Children from all walks of life receive education under the same roof which helps us maintain a favourable and amicable environment at school. It is our attempt at giving the underprivileged students a chance to interact with their relatively privileged counterparts and feel included.
