Dear Colleagues:

The National Science Foundation's (NSF) Directorate for Computer and Information Science and Engineering (CISE) has changed the proposal submission due dates for the Computer and Information Science and Engineering (CISE): Core Programs solicitation (NSF 23-561).

The changes include three key points:

• The MEDIUM Projects and OAC Core Projects submission deadlines have changed. The new submission window for these project classes is October 1 to 23, 2023, and October 1 to 23, annually thereafter.
• MEDIUM Projects and OAC Core Projects submitted before December 23, 2022 do not count towards the limit on the number of proposals per PI, co-PI, or Senior Personnel
• Although proposal submissions to the SMALL Projects class are "Accepted Anytime", Research.gov requires a “due date” and displays one for you to select. You can choose any listed deadlines in Research.gov from the Due Date drop down window to submit to the SMALL Projects class.

Sincerely,

Margaret Martonosi
Assistant Director
Computer and Information Science and Engineering
