What is the future after doing a PG in rural development from IGNOU?

It's one of those insignificant programs that won't help you advance in your career. MA courses in rural development or MA courses in public administration are worthless yet they are useful in Social Work though. However, too many have MSW degrees and are preferred over MPA and MARD candidates. Even in the government sector, Master's degrees in social work or sociology are required.

So it makes no difference whether you enroll in this PG program at IGNOU or another university. It might not work. You can, however, use this as a postgraduate degree. You should pursue a postgraduate degree in social work.
