There is a wide variety and range regarding almost every aspect of the functioning of VTCs. Geographically, for example, the VTCs are situated in villages, small towns, district headquarters and metro cities like Chennai and Hyderabad. Some have a handful of trainees per batch while others have a few hundreds. Some are new and have run a few batches as of December 2019, while others have been running for several years and have run more than 100 batches. The duration of courses also varies greatly – from a minimum of 10 days to a few that run for 6-9 months.
