Step 1: Project Pitch

NSF requires that you submit a Project Pitch. You may submit your Project Pitch at any time, and you will usually hear back within one month. If your Pitch is accepted, then you will receive an official invitation from the Program Director to submit a full proposal. Only one Project Pitch or Full Proposal is allowed in the NSF pipeline at a time.

Step 2: Full Proposal

You must submit your Full Proposal within the next two deadlines of the email date of your official Project Pitch acceptance. Proposals are then reviewed three times per year at the close of each submission window: Nov. 6, Mar. 5, and July 2. Only one Project Pitch or Full Proposal is allowed in the NSF pipeline at a time.

Step 3: Proposal Review & Decision

Proposals are reviewed by a panel for intellectual and technical merit, broader impacts, and commercial impact. You will usually be notified 5-7 months after your respective submission window closes whether your proposal is accepted or declined. You must wait for a determination from NSF on the pending proposal before submitting a new proposal in the next window.
