hello there

i cannot provide you the exact information but i can hep you a bit. first NIT trichy is a NATA participating college so one can expect it to be registered under coa. but i have checked the council of architecture 2016 list and nit trichy wasn't present in that list so i am not sure whether it is registered or not .the best way is to contact the college through their contact list and ask directly .here is the link for department page
