What is the reason behind the low rank of NIT Warangal and NIT Calicut in MHRD, NIRF ranking?

As some of my friends are from NIT Calicut, I might be able to share some information about the college I gathered from them.

• The major reason for the diminishing NIRF ranking is its lack of proper administrative procedures during MHRD document verification.
• The details about the alumni network are really poor.
• Another reason is the college is trying to maintain its age-old legacy by keeping the infrastructure as it is.
• They are rarely repaired, There is no construction of new buildings.
• Even the facilities are old and are not replaced by modern technologies.

If you think that the drop in the rankings is because of the quality of education, faculty, or placements, let me assure you that it is not. Because NIT Calicut is still considered among the top 4 NITs.
