Graduates founded the NIT Alumni Network in November 2002 as a registered association. It is a self-governing association of alumni for alumni, closely cooperating with the Alumni Team at the NIT.

The principal objective of the alumni association is to maintain close personal and professional ties between classmates and members of different classes: keeping in touch and supporting each other in many ways via the valuable, close-knit, lifelong network founded at the NIT. The Board of the association hosts the Homecoming Weekend and launched the One of Us project.
