Which course is better to do at NIRDPR, i.e. a one-year or two-year programme?

If you already have a master's degree and want to get into the development sector, then pursuing the one-year-long PGDRDM is a better option. It is more practical oriented. But if you are a graduate and want to build a strong academic profile before joining this sector, then choosing the 2-year long course is better. It is an AICTE approved program. However, both courses require you to have a bachelor's degree.
