NSF requires you to report on your project at two junctures:

• Annual Project Report. Required at least for each year except the last of a multi-year award, project reports go to your program officer, who uses them to monitor and report on the progress of your project.

• Final Project Report. Required within ninety days after your award ends.

The information you and other PIs provide through these stages of reporting is also used by your program officer, by NSF, and by other audiences – including Congress and many other non-scientific audiences – to report on and evaluate the results achieved by your program, its parent organization, and NSF. NSF welcomes and encourages you to update your report at any time by submitting an:

• Interim Report. Using this option you can update the information on record about your project at any time during or after the award period.
