Vinoba Bhave University Doctoral Eligibility Entrance Test ( DEET ) Entrance Examination

Vinoba Bhave University, Jharkhand, came into existence as a teaching-cum-affiliating state university on the 17th of September, 1992, after the bifurcation of Ranchi University, by Act 3 of 1990 passed by Bihar Assembly.It fell under Jharkhand after the creation of the state on November 15, 2000. Its headquarters is at Hazaribag, a town of sylvan surroundings and tranquillity amid verdant forests.

Vinoba Bhave University Hazaribag is conducting the DEET 2017. Details of conduct of Doctoral Eligibility Entrance Test ( DEET ), 2017 are given here for interested applicants.
