Authorship Criteria Versus Contributorship: The ICMJE Criteria and the CRediT Contributor Roles Taxonomy

ICMJE defines authorship by four specific criteria that all must be met. Contributorship, formalised through taxonomies such as CRediT (Contributor Roles Taxonomy), recognises specific types of contribution — data curation, methodology, writing, supervision, and others — made by anyone involved in the work, whether or not they meet the full authorship bar.

The four ICMJE authorship criteria and the requirement to meet all four

ICMJE's recommendations on the role of authors state that authorship should be based on meeting all four of the following: a substantial contribution to the conception or design of the work, or the acquisition, analysis or interpretation of data; drafting the work or revising it critically for important intellectual content; final approval of the version to be published; and agreement to be accountable for all aspects of the work, ensuring questions about its accuracy or integrity are appropriately investigated and resolved1. ICMJE is explicit that satisfying only one or two of these — for example, acquiring funding or providing general supervision alone — does not, by itself, justify authorship.

Purpose of the CRediT contributor taxonomy

Allen, Scott, Brand, Hlava and Altman, introducing the CRediT taxonomy, describe the problem it addresses: traditional authorship bylines and free-text acknowledgments fail to capture, in any standardised or searchable way, the specific nature of each person's contribution to a published work2. CRediT defines a fixed set of contributor roles — including conceptualization, data curation, formal analysis, investigation, methodology, project administration, software, supervision, validation, visualization, and writing (original draft and review/editing) — that can be applied to every person who contributed meaningfully, whether or not they qualify as an author under ICMJE's criteria.

Distinction between contributor status and authorship

A person can be a legitimate contributor — recognised by a CRediT role such as “data curation” or “software” — without meeting all four ICMJE authorship criteria, and such contributors should be acknowledged with their specific role stated, rather than being omitted entirely or granted authorship for which they do not fully qualify. The reverse does not hold: anyone who meets the full ICMJE authorship criteria should be listed as an author, not merely credited as a contributor1. Using both frameworks together — ICMJE to determine the byline and CRediT to describe what each author and non-author contributor did — provides a more complete and transparent account of individual contributions.
