State of CRediT adoption — 2026

Why “CRediT adoption” resists a single number

“Publisher X supports CRediT” can mean several genuinely different things, and publishers rarely specify which one they mean: a policy that mentions CRediT in author guidelines; a submission-system field where authors pick roles from the controlled vocabulary; structured JATS XML with a canonical NISO role URI on each contributor; a Crossref deposit that carries the role metadata; or propagation of that role data onto contributors' ORCID records. A publisher can be genuinely truthful in saying “we support CRediT” while doing any one of these without the others. CASRAI does not have a verified, sourced measurement of how many publishers clear each of these layers — no study we could locate publishes that breakdown — so rather than estimate percentages, this section names the distinction and leaves the quantification for future work (see the note on the Hosseini et al. 2026 paper below, which is the most promising lead we found).

The official registry, and its limits

The single best current source for “who has adopted CRediT” is NISO's own maintained adopter registry at credit.niso.org/adopters. As of this review it lists:

• 40 named publisher/society adopters — including AACR, BMJ, Cambridge University Press, Cell Press, eLife, Elsevier, Frontiers, MDPI, MIT Press, Oxford University Press, PLOS, SAGE, Springer, and Wiley-VCH.
• 14 integrator/vendor adopters — submission-system and workflow vendors including Aries Systems/Editorial Manager, Clarivate/ScholarOne, Coko/PubSweet, Scholastica, and Worktribe.
• 3 publishing-outlet platforms — Gates Open Research, HRB Open Research, and Wellcome Open Research.
• 1 institution — the University of Glasgow.

The registry does not itself state a running total, and it is a self-reported, publisher-submitted list rather than an independently audited census — so it almost certainly undercounts real adoption to some degree. What it is useful for is the opposite: it is reasonable evidence about who has not formally registered. Some names conspicuous by their absence: IEEE has no listing and CASRAI found no public IEEE statement on CRediT anywhere. PNAS is absent — its author-contributions field remains free-text rather than the controlled CRediT taxonomy, though PNAS did publish a 2018 commentary by Holcombe et al. advocating standardized contributor roles. Taylor & Francis does not appear as a distinct registry entry, despite being widely assumed to support CRediT across its portfolio. ACMis also absent; CASRAI found no primary-source confirmation of ACM adoption anywhere, despite claims to the contrary circulating in some AI-generated search summaries.

A verified timeline

Rather than a synthetic adoption curve, here is every dated, sourced individual adoption event CASRAI could verify against a primary source — the publisher's own announcement or the NISO registry's own dated entry:

One entry worth flagging explicitly: the ACS entry above is a pilot (18 journals, optional, not required) rather than a full-portfolio mandate — treat “adopted” on any adopter list as a spectrum, not a binary, per the layer distinction above.

The freshest real development: Crossref Schema 5.5

The most concrete, dated, verifiable news in the CRediT ecosystem this year did not come from a publisher announcement — it came from Crossref. On July 9, 2026, Crossref released deposit Schema 5.5, whose headline addition is native support for multiple CRediT contributor roles per person inside the standard contributors element. Crossref's own announcement describes this as the schema's “most significant enhancement,” explicitly citing compatibility with “CRediT (Contributor Roles Taxonomy): a community-owned taxonomy of 14 contributor roles,” and frames adoption as incremental — publishers “can be adopted gradually, where it fits your editorial or production workflow.” Existing deposits using the older single-role attribute continue to work unchanged.

This matters more than another publisher press release would, because Crossref sits downstream of every publisher's submission system and upstream of ORCID auto-update and most institutional CRIS ingestion. A schema-level fix to how many roles a single contributor can carry removes a structural bottleneck that existed regardless of how good any individual publisher's intake form was. Whether publishers' production pipelines actually start emitting the richer metadata is, as with everything else in this article, a separate and currently unmeasured question.

The one paper worth reading — once it's accessible

Hosseini, Kerridge, Allen, Kiermer & Holmes published “Enhancing, Understanding and Adoption of the Contributor Roles Taxonomy (CRediT)” in Learned Publishing on March 19, 2026 (DOI 10.1002/leap.2048). Two of the authors — Liz Allen and Véronique Kiermer — are among CRediT's original architects, and the paper is co-written from within the CRediT Standing Committee, the body NISO formed to steward the taxonomy after 2022 standardization. The publicly visible abstract confirms the Standing Committee has developed worked examples mapping research tasks to each of the 14 roles, states CRediT “has been adopted by hundreds of journals,” and flags that “further integration of CRediT within scholarly communication will require ongoing attention to technical, social, and financial challenges” — alongside the Crossref centralization point covered above. The full text sits behind a Wiley paywall; CASRAI was unable to access it directly and is not in a position to cite figures from it beyond the abstract. If your institution has Wiley access, this is the single most promising source for a real, current adoption statistic, and we'll update this article if we can obtain the full text.

Note the “hundreds of journals” figure from this March 2026 abstract sits well below NISO's own Feb 2022 “thousands of journals” claim. We cannot reconcile the two — they may be counting different things (registered publisher policy vs. active structured usage) — and flag the discrepancy rather than pick one.

The narrative-CV context

The clearest institutional link between CRediT-style contribution data and researcher evaluation is UKRI's Résumé for Research and Innovation (R4RI), a narrative-CV framework trialled across UKRI funding calls since 2021. Its use expanded after The Funding Service replaced Je-S as UKRI's submission platform in January 2024, though R4RI is not universally mandatory — individual funding-opportunity guidance specifies whether and how applicants should use it. We could not verify that any funder currently mandates a CRediT statement at the grant-application stage specifically, and do not assert one does.

What CASRAI recommends

These are editorial recommendations, not measured facts:

1. Publishers already on the NISO registry: consider whether Schema 5.5's multi-role support changes what your production pipeline can now emit to Crossref.
2. Publishers not yet on the registry (including Taylor & Francis, IEEE, ACM, and PNAS): a public statement of position — adopted, piloting, or declined — would resolve a genuine ambiguity that currently exists in the public record.
3. Institutions: don't treat “Publisher X is on the CRediT registry” as evidence that role data actually reaches your CRIS — verify the specific pipeline (JATS → Crossref → ORCID/CRIS) for the journals your researchers actually publish in.
4. Researchers: if your publisher captured CRediT roles at submission, check whether they show up on the article's Crossref record and your ORCID profile. If they don't, that gap is common, not unusual.
