The Institute was renamed as National Institute of Criminology and Forensic Science (NICFS) in 1991 and again renamed after Lok Nayak Jayaprakash Narayan in 2003. In 43 years of its existence, the Institute has made significant headway in the areas of training of criminal justice functionaries and others, as well as research in applied aspects of the twin subjects.
Since 2004, the Institute has been offering M.A./M.Sc. degree courses in Criminology and Forensic Science, which are open to general public.
