Call for Researchers: What It Means & Vetting

What “call for researchers” means

“Call for researchers” is a plain-language, funder-agnostic term for a public solicitation inviting researchers to submit proposals for funding — a grant, fellowship, collaborative research program, or award. It’s used loosely across government funding councils, private foundations, corporate research programs, and international bodies to mean the same thing more formal terminology names precisely: an open competition for research funding, with a defined scope, eligibility criteria, and submission deadline.

It is functionally a synonym for “call for proposals,” “funding call,” “request for proposals (RFP)” in the research context, and “funding opportunity” — the exact label a given funder uses is mostly a matter of institutional convention, not a different underlying process.

Call for researchers vs. call for papers: a common mix-up

“Call for researchers” is frequently confused with call for papers (CFP), but the two solicit fundamentally different things:

Call for researchers / call for proposals — asks for a research proposal: a plan for work not yet done, submitted to compete for funding to carry it out. The output of a successful submission is a grant or award.
Call for papers — asks for completed or in-progress research findings, submitted to a journal or conference for publication or presentation. No funding changes hands; the output is a publication slot or conference presentation.

The confusion is understandable because both are formal, deadline-driven solicitations aimed at researchers, both get circulated through similar channels (society mailing lists, aggregator sites, institutional research offices), and both are targeted by scams that mimic the same legitimate format. But confirming which kind of call you’re looking at is the first step in evaluating it — the verification steps differ, covered below.

How “call for researchers” maps to formal funder terminology

Research administrators rarely see “call for researchers” as an official document title — funders use their own precise terms, and knowing the mapping helps when a colleague or investigator uses the informal phrase and you need to identify what they actually mean:

NIH issues a Funding Opportunity Announcement (FOA) — renamed Notice of Funding Opportunity (NOFO) for announcements issued from 2023 onward, though “FOA” remains embedded in NIH’s own Grants Policy Statement numbering. Every NIH FOA/NOFO is either an RFA (Request for Applications) — a one-time competition with set-aside funds and a dedicated review panel — or a Program Announcement (PA, PAR, or PAS), which is standing and recurring.
NSF doesn’t use FOA/NOFO terminology at all. Per its Proposal & Award Policies & Procedures Guide (PAPPG), NSF’s hierarchy runs from a broad, standing Program Description, to a more formal Program Announcement, to a focused, time-limited Program Solicitation (the closest NSF equivalent to an NIH RFA) — plus a separate Dear Colleague Letter (DCL), which signals funder interest without itself being a funding announcement.
Federal agencies government-wide were directed, under OMB’s 2024 revision to the Uniform Guidance (2 CFR Part 200, Appendix I), to standardize on “Notice of Funding Opportunity (NOFO)” as the common term, replacing agency-specific labels for awards issued on or after October 1, 2024.
Non-US and multinational funders — UKRI, Horizon Europe, national research councils such as South Africa’s NRF or Australia’s ARC — typically just say “call” (a Horizon Europe “call,” a UKRI “call for proposals”), which is where the informal “call for researchers” phrasing is most often used verbatim, including by the funders themselves.
Private foundations and corporate research programs (e.g. disease-specific foundations, corporate research-award programs run by technology and industry funders) almost always use “call for proposals” or “call for research proposals” rather than any of the government-specific terms above.

Where legitimate calls for researchers are published

The reliable discovery channels mirror the ones used for call for papers, with funding-specific additions:

The funder’s own website — always the authoritative source. For US federal funding, that means the awarding agency’s site and Grants.gov, which aggregates NOFOs across federal agencies (an institution must complete Grants.gov registration before an authorized official can submit through it).
Funder-run portals — NIH’s Guide for Grants and Contracts, NSF’s Research.gov and PAPPG-referenced solicitation pages, the European Commission’s Funding & Tenders Portal for Horizon Europe calls.
Aggregator and discovery databases — commercial and institutional tools such as Pivot-RP and GrantForward compile funding opportunities across thousands of funders, searchable by discipline, career stage, and deadline. Like call for papers aggregators, these are discovery tools, not vetting mechanisms — listing does not itself confirm legitimacy.
Institutional research/sponsored-programs offices — most universities’ research offices curate and circulate funding opportunities relevant to their faculty, which functions as an informal first filter similar to a library’s CFP guide.
Disciplinary and professional societies — many run their own smaller research-award programs and circulate calls from aligned funders to their membership.

How to evaluate whether a call for researchers is legitimate

Genuine research-funding calls and predatory or scam solicitations both circulate through the same channels, so the same discipline that applies to vetting a call for papers applies here, adapted to what a funding scam actually looks like:

Verify the funder independently. Go to the funder’s own official website directly, not just the link in the email or aggregator listing, and confirm the specific call is posted there with matching details (scope, deadline, award amount).
Treat any request for payment as a hard stop. Legitimate research funders do not charge an applicant an “administrative,” “processing,” or “registration” fee to submit or receive a research grant. A demand for payment before funds are released is one of the most reliable signals of a funding scam, distinct from the CFP world, where fees (APCs, registration) are normal and disclosed — the direction of money flow is the tell: in a legitimate call, funding flows to the researcher, not from them.
Be skeptical of guaranteed or unusually fast funding decisions. Genuine competitive review — whether NIH study section review, an NSF panel, or a foundation’s scientific advisory board — takes real time and involves real named reviewers. An offer of funding within days of a first contact, with no defined review process, doesn’t match how research funding actually works.
Check that the eligibility and institutional-affiliation requirements make sense. Most legitimate research funding requires an eligible institution to receive and administer the award (via its sponsored-programs or grants office) rather than paying an individual directly with no institutional oversight; a call that bypasses this entirely is unusual for anything beyond genuinely individual fellowships, and even those are administered through a named, verifiable program.
Watch the same language red flags as CFP scams — excessive flattery, generic salutations, urgency pressure (“apply within 48 hours”), and overuse of “global”/”prestigious” without independently verifiable evidence.
Cross-check with your research office. Sponsored-programs and research-development offices deal with funding opportunities daily and can usually confirm within minutes whether a specific call or funder is one they recognize.

What a call for researchers typically requires

Requirements vary by funder and mechanism, but most calls for researchers ask for some combination of: a letter of intent or pre-proposal (used by some funders to gauge volume before inviting full proposals), a full research narrative or project description, a budget and budget justification, biosketches or CVs for the research team, letters of institutional or collaborator support, and confirmation of any required compliance approvals (human subjects, animal welfare, biosafety, conflict of interest) relevant to the proposed work. CASRAI’s guides on letters of support and budget justification narratives cover two of these components in more depth.

Frequently asked questions

Is “call for researchers” the same as “call for proposals”?

Yes, in practice. Both describe an open solicitation inviting researchers to submit a proposal in competition for funding. Neither is a formal, universally standardized term — individual funders use their own precise labels (FOA/NOFO, RFA, Program Solicitation, or simply “call”) for the same underlying process.

What’s the difference between a call for researchers and a call for papers?

A call for researchers solicits proposals competing for research funding; a call for papers solicits completed or in-progress research findings for journal publication or conference presentation. See the section above for the full comparison.

How can I tell if a call for researchers is a scam?

The single most reliable signal is money flow: a legitimate research funder pays the researcher or their institution, never the other way around. Any solicitation that asks the applicant to pay a fee before funding is released should be treated as a strong scam indicator. Verifying the funder directly on its own official website, and checking with your institution’s research office, resolves most cases quickly.

Where can I find legitimate calls for researchers in my field?

Start with your institution’s research or sponsored-programs office, which typically curates relevant opportunities; funder-run portals such as Grants.gov (US federal) or the EU’s Funding & Tenders Portal (Horizon Europe); and discipline-specific aggregators such as Pivot-RP or GrantForward, which most universities provide access to.
