Resubmitted proposals involve significant effort--not just yours but also the community's, as resubmissions are often assigned to new reviewers.
Proposals focused on an area in which the PI has prior accomplishments tend to get the best reviews.
If you list multiple programs on the cover sheet, list first the program most central to your topic.
A critical point to consider is whether the idea you're proposing is easily differentiated from the work included in your existing grants.
This article provides suggestions and ideas about how to make your next National Science Foundation (NSF) proposal more competitive.
NSF provides proposal information in a variety of ways: Dear Colleague Letters, Program Descriptions, Announcements, and Solicitations.Your proposal should not look too similar to work that is already funded; even titles and summaries should be distinct.The new proposal should go beyond your already-funded work in terms of both intellectual merit and broader impacts.In certain types of proposals, broader impacts tend to take up even more space.For example, a successful CAREER (Faculty Early Career Development) proposal typically will include three to five pages on broader impacts, focused specifically on the integration of research and education and its likely impact.Be very clear about what you expect to accomplish scientifically, why it matters, and how it's different from what others have done. Finally, ask yourself: If the project is successful, will it make an important impact?Explain in your proposal why you want to do the work–-your motivation and the scientific rationale.If you do not have documented expertise in the area, consider adding a co-PI who has that expertise or waiting until you have some preliminary results.A strong application always demonstrates an appreciation of the background of the field, with appropriate references to the results of others.This factor is critical for the success of renewals and future submissions.Before resubmitting a proposal, consider each of the reviewers' concerns and, if you want, contact the program director to gather further insight into how the proposal might be improved.
