As of April 24, 2017, NSF will require the use of a spreadsheet template for identifying Collaborators and Other Affiliations information for Principal Investigators (PIs), co-PIs, and other senior project personnel identified on FastLane proposals. This is the template that CISE has been using for Collaborators information. Be sure to load it as an xls or xlsx and let FastLane do the conversion on it (do not pdf it beforehand). A separate form will be uploaded for each individual on the proposal.
The template and associated instructions may be accessed directly at https://www.nsf.gov/bfa/dias/policy/coa.jsp
All are strongly encouraged to complete the form well before a proposal deadline is looming, as it will take some time. The good news is that once you have completed this template, you can reuse it for subsequent proposals, only updating as needed.
