The National Science Foundation has released a revised Proposal and Award Policies and Procedures Guide (18-1), which will be effective for proposals submitted on or after January 29, 2018.
A few of the significant changes are:
- The budget justification page limit will be increased from 3 pages to 5 pages
- The Collaborators & Other Affiliations template that has been in pilot phase will become mandatory
- Project Descriptions will be required to have a section labeled "Intellectual Merit", in addition to the already required "Broader Impacts" section
