Hope you are doing great. Broadly, there are many things that need to be look into for calculating the rank or rating of any of the colleges. They can be divided into nine categories: student excellence, faculty resources, expert opinion, financial resources, social mobility, graduation and retention, graduation rate performance, graduate indebtedness, and alumni giving. You can find NAAC ratings on the college's website by going there and using the NAAC ratings.
