ISM Dhanbad got the IIT tag a few years back.
It offers pretty good placements and research facilities. The campus is well-maintained and of decent size. It is being further improved and even has its own mall now. Other than that, the college has a fully centralized air-conditioned technical library- the largest in Asia.
IIT Dhanbad is at par with the old IITs. It is the best college in India for Earth Science branches (Mining, Mining Machinery, Applied Geology, Mineral, etc). Other branches have also developed in recent years, especially since ISM has received the IIT tag.
This institute has one of the largest alumni networks in the public sector. It has an MHRD-funded faculty development centre, which is one of its kind in the entire country. It is constructing a Central Research facility within its campus, in collaboration with Australian universities, as a result of an MoU signed by PM Modi during his visit to Australia a few years back. Many centrally funded projects are also taking place within the campus.
So IIT Dhanbad is far ahead of new IITs and at par with the old ones.
