GOVBIDFIT SCREENING LENS

What deserves attention before you spend bid time

Decision support

These screening signals are generated from the public notice fields stored for this specific opportunity. They are not eligibility findings or predictions; they are prompts for a faster, more disciplined review of the official solicitation.

Active solicitation stage

This record is in a solicitation stage, so submission instructions, evaluation factors, attachments and amendments should be reviewed before a bid/no-bid decision.

Planning window available

The stored response date leaves more than ten days, but amendments and pre-response milestones can shorten the usable preparation window.

Eligibility gate recorded

No Set aside used is recorded as the set-aside or restriction. Confirm the bidding entity actually satisfies the applicable program and size requirements before investing proposal time.

Classification signal

NAICS 541715 · PSC AJ12 is the recorded classification. Use it as a screening clue, then compare the actual scope and deliverables rather than treating the code alone as proof of fit.

What this opportunity record tells you

SAM.gov identifies this as a solicitation from NATIONAL SCIENCE FOUNDATION. The record was posted on September 18, 2026 and currently lists January 7, 2027 as the response deadline. GovBidFit keeps source facts separate from its matching guidance so you can see what comes from the federal notice.

The listed product or service classification is NAICS 541715 · PSC AJ12. The set-aside field is No Set aside used. These fields help narrow your search, but they do not replace the full solicitation, amendments, attachments, clauses or eligibility language on the official source.

Before deciding to bid

Read the complete official description and scope. Verify the exact response date, time and time zone on SAM.gov. Confirm NAICS/PSC and every set-aside eligibility requirement. Review attachments, amendments, Q&A and submission instructions. Check place of performance, staffing, insurance, bonding and execution requirements.
Source and trust

GovBidFit is independent and is not a U.S. government website. GovBidFit stores a structured mirror of SAM.gov public opportunity data in its own database and keeps the compact snapshot as a fallback. The official SAM.gov notice remains the controlling source. The official SAM.gov notice controls if anything here differs from the source or a later amendment.
