Dear Simna,

You can check the counselling criteria below

Universities/colleges and states offering B.Arch programmes will conduct their own separate counselling based on NATA scores for admission. These institutes will conduct the NATA counselling after the declaration of result by COA, for the qualified candidates. Candidates who wish to participate in NATA counselling 2018 must check and meet the eligibility criteria of the university/college to which they are applying for.
