In general, The admission in MNNIT in M.Tech programs are given in the following three categories :
1. Admission to students who qualify through GATE ( For M. Tech. in Comp. Sc., and M.Tech. Software Engg. there will be an additional entrance test).
2. Admissions to college teachers through the Quality improvement Programme.
