“NIELIT Guwahati” is in operation w.e.f. 5th August’1998, in the name & style of “CEDTI Tezpur” after signing of an MOU between Tezpur University & erstwhile Dept. of Electronics, Govt. of India. The centre started its operations from the Tezpur University campus at Na Paam near Tezpur. However, due to operational difficulties, the location was later shifted to Law College Campus, Tezpur.

As per decision of the Executive Committee meeting held on 18-7-2002, the CEDTI, Tezpur has been re-named as “CEDTI, North East (Upper)” with area of operation extending to the states of Assam , Arunachal Pradesh, Meghalaya and Sikkim and to initially function from Guwahati and Tezpur with administrative set up at Guwahati. After the merger of CEDTI’s with DOEACC Society (except CEDTI, Mohali) in December’2002, the centre was renamed as DOEACC Centre Guwahati/ Tezpur and later on as the “DOEACC Society Guwahati/ Tezpur Centre”. In October’2011, DOEACC Society was renamed as “National Institute of Electronics & Information Technology” in sort “NIELIT” and the centre is thus renamed as “NIELIT Guwahati”.

In April’2012, the union cabinet has approved a project under Ministry of Electronics & Information Tecnology (MeitY), Govt. of India named as  “Development of the North Eastern Region by enhancing Training/ Education capacity in the IECT Area” under which 6 (six) existing NIELITs of the NE region located at Imphal, Aizawl, Guwahati, Shillong, Gangtok, Itanagar are to be upgraded as NIELITs with own campus and also create/upgrade 12 (twelve) Extension Centres in the entire NE region in order to increase training capacity of the NIELITs in the NE region. Of the 12 (twelve) Extension Centres, 5 (five) are to be commissioned in Assam at locations Tezpur, Jorhat, Dibrugarh, Kokrajhar and Silchar under NIELIT Guwahati.

The NIELIT Extension Centres at Dibrugarh, Jorhat , Kokrajhar and Tezpur are  presently operational from newly constructed permanent campuses  whereas Guwahati Centre and Silchar EC is operational from rented premises.

Presently NIELIT has established a Centre in all the state capitals of the NE region and accordingly the jurisdiction of NIELIT Guwahati is now restricted to the state of Assam only.
