The journey of IISF was started with its inaugural event at Delhi in 2015. Six editions of IISF have been organized since then in northern, southern and the eastern regions of the country. The pandemic in 2020 due to Covid19 posed a serious challenge for the conduct of this annual event, but the challenge was overcome by conducting the event on a virtual platform to maintain the uninterrupted flow of journey.
Responsibility of conducting this mega annual event is given either to one of the departments of the Ministry of Science and Technology, viz. DST, CSIR and DBT or to the Ministry of Earth Science in rotation. Several other ministries and departments related to S&T have always been involved in the organization of the event. Vijnana Bharati has been a consistent organizing partner in the forward march of IISF.
IISF has evolved progressively through its innovative design of programs and activities connecting various aspects of life to science. Representation of the diverse strata of society in the event has emerged as a remarkable feature of IISF. The number of participants from India and abroad has grown steadily with every edition and the journey is on involving more and more people to attain the desired outcome.
