NSF Graduate Research Fellowship Program (GRFP)

NSF GRFP is out 2.5 months late w/key changes

1. 2nd year graduate students not eligible.

2. "alignment with Administration priorities"

3. Unlike prior years, they DO NOT specify the expected number of awards... that is a BIG problem.

What this administration is teaching Universities is that even if you comply - punish students for protests, ban masks, remove DEI from websites and classes - they will still defund you and try to break you apart. Basically, there is no point in complying.
