Yes. There are grants for Graduate Students. You should consult your college advisor or professor because they can offer some sources of these grants. Often times in Graduate school professors are conducting research and they have already been awarded grant money. They may be able to employ you or you can get a job with the university and they will offer you reduced fees to attend classes. You should check to see if you university has a GGC-Graduate Grants Committee.
You may also be able to obtain graduate grants from private organizations and corporations that support students' research projects in specialist areas of study. Minority foundations and organizations are another popular source for graduate grants and fellowships for graduate students from ethnic populations, for example; the American Indian Graduate Center provides grants to and scholarships for American Indians and Alaskans pursuing graduate degrees.
