Hello aspirant,

Your college or Institute will renew the NBA Accreditation by providing the evidence, improvements, quality of education, work they have done to whomsoever is concerned.If your college has been doing well in all the years then your college will acquire NBA accreditation for the extended years.And if your college fails to acquire it for any branch unfortunately it cannot certify you as a candidate who passed graduation in a NBA accredited college.Do not worry, check the past years performance of your college.

I hope this is helpful.
