In 2003 seventeen erstwhile Regional Engineering Colleges (RECs) were rechristened as National Institute of Technology (NITs) were taken over as fully funded institutes of the Central Government and granted deemed university status. In addition, Central Government has also taken over some Other college, and converted them into National Institute of Technology(NITs). Thus the total number of NITs has gone up to 30 and the total sanctioned strength for the NITs is 15165 (2009-10).
