I agree with stilrsnation's thoughts on this issue. Although, I think realistically there are probably a few candidates that will still be eliminated. More than likely, some folks will not accept EPA STAR because they may have accepted other fellowships. This would then free up a fellowship to give to other students who have not been denied yet but may be ranked at the bottom end of the stack. I can't imagine they would deny a student first by mail only to turn around and offer a fellowship later. More than likely the secrecy is related to offering first tier candidates fellowships, see who takes them, then offer second tier candidates fellowships and so on. At the end, some students will accept and others will decline and their may be a few left at the end that will still be denied.
