NSF FastLane (Legacy Grants Portal)

NSF FastLane was the National Science Foundation’s original electronic system for preparing and submitting grant proposals and administering active awards, in continuous use from the 1990s through the early 2020s. It has been decommissioned as a submission channel and is not a system a principal investigator or sponsored-programs office can use to submit a new NSF proposal today.

What FastLane did

At its peak, FastLane handled the full NSF proposal-and-award lifecycle for the research community: proposal preparation and electronic submission, panel review support, award notifications, and post-award administration functions such as project reports. It long predated the more granular, form-driven interfaces research administrators now expect, and NSF progressively migrated pieces of that lifecycle out of FastLane and into Research.gov over more than a decade before finally retiring the submission function itself. See eRA Commons vs. Research.gov for how NSF’s current system compares to NIH’s electronic-research-administration platform.

Current status: decommissioned for submissions

FastLane is no longer a live proposal-submission system. Per NSF’s Proposal & Award Policies & Procedures Guide (PAPPG NSF 23-1), FastLane was removed as a proposal-submission option for all NSF funding opportunities effective January 30, 2023. NSF phased out most of FastLane’s remaining functions — award documents, organizational reports, and Grants.gov integration — in the months that followed, including a further decommissioning phase in November 2023. The fastlane.nsf.gov domain itself now 301-redirects to research.gov, which is the practical, verifiable confirmation that there is no active FastLane instance left to log into for new work.

This was not a single, one-time cutover. NSF had already moved all project reporting — annual reports, final project reports, and the Project Outcomes Report — out of FastLane and into Research.gov years earlier, effective March 18, 2013. The 2023 change was specifically about proposal submission, the last major function FastLane still handled by that point.

What replaced it

Research.gov is NSF’s current system of record for proposal preparation and submission, award management, and reporting; it is the direct functional successor to FastLane, not a parallel option. See NSF Funding Search for how researchers use Research.gov to discover open solicitations. Grants.gov remains an alternate submission pathway for certain NSF funding opportunities, as it did before the FastLane retirement, so an institution may legitimately submit an NSF proposal through either Research.gov or Grants.gov depending on the specific program solicitation — but never through FastLane.

Worked examples

• Legacy documentation reference: A sponsored-programs office locates an NSF award file from 2018 that references a “FastLane proposal number.” This is a correct historical usage — the award predates the 2023 retirement and was genuinely processed through FastLane.
• Institutional process guide that needs updating: A university’s internal grants-administration handbook still instructs PIs to “log into FastLane to submit your NSF proposal.” This is now inaccurate and should be corrected to reference Research.gov (or Grants.gov, where applicable) as the current submission system.

Counter-example

A PI preparing a new NSF proposal in the current award cycle who is told to submit “through FastLane” is receiving outdated guidance. There is no FastLane submission workflow to complete; the correct action is to prepare and submit via Research.gov, consistent with the current PAPPG.

Why this still matters for research administrators

FastLane remains a live term in research-administration vocabulary for two practical reasons: first, historical award records, older training materials, and some institutional SOPs still reference it, and administrators need to recognize it as a legacy reference rather than a current option; second, the FastLane-to-Research.gov transition is a useful case study in how funder electronic-research-administration (eRA) systems evolve over time — comparable to NIH’s own long-running consolidation of proposal and reporting functions into eRA Commons, discussed in the eRA Commons vs. Research.gov comparison.
