Authorship & Editorial Ethics

CRediT Author Statement: 14 Contributor Roles & Templates (2026)

12 min read•Updated October 2026•NISO Z39.104 Standard

Authorship disputes remain among the most common and damaging ethical conflicts in academic research. For decades, scientific credit was inferred solely from author order—with first authors assuming primary execution credit and senior authors claiming supervisory prestige. However, in modern multidisciplinary science involving bioinformaticians, clinicians, statisticians, and laboratory technicians, traditional author lists fail to capture who actually performed the work.

To establish transparency and eliminate honorary, guest, and ghost authorship, major publishers—including Elsevier, Wiley, Springer Nature, PLOS, and Taylor & Francis—have adopted the CRediT (Contributor Roles Taxonomy) standard (formalized as ANSI/NISO Z39.104-2022).

When submitting a research paper through Editorial Manager or ScholarOne, you will be prompted to provide a formal CRediT authorship contribution statement. This technical guide explains all 14 standardized contributor roles, details exact punctuation syntax, provides copy-pasteable templates for common lab structures, and illustrates proper placement in Microsoft Word.

Elsevier & Editorial Manager Mandate: In over 2,000 Elsevier journals and hundreds of partner titles, submitting a CRediT statement is a mandatory checkpoint. Manuscripts without a dedicated "CRediT authorship contribution statement" heading in the Word file will be unsubmitted by technical editorial assistants prior to peer review.

The 14 ANSI/NISO CRediT Contributor Roles Defined

The CRediT taxonomy comprises exactly 14 standardized roles. When authoring your statement, use these exact role titles. Do not invent colloquial roles such as "Lab Manager" or "Data Collection"—map all research activities into these 14 categories:

CRediT Role	Official NISO Definition	Practical Research Examples
Conceptualization	Ideas; formulation or evolution of overarching research goals and aims.	Developing the initial scientific hypothesis; designing the overarching project scope.
Data curation	Management activities to annotate, scrub, and maintain research data.	Formatting sequencing reads; archiving datasets into Zenodo/Dryad; data scrubbing.
Formal analysis	Application of statistical, mathematical, or computational techniques to analyze data.	Running ANOVA, regression, machine learning training, or biostatistical pipelines.
Funding acquisition	Acquisition of financial support for the project leading to this publication.	Writing grant proposals (NIH, NSF, Horizon Europe); securing internal department funds.
Investigation	Conducting the research and investigation process, specifically performing experiments.	Pipetting assays; running wet-lab protocols; conducting patient interviews; field surveys.
Methodology	Development or design of methodology; creation of models.	Synthesizing new chemical compounds; designing novel algorithmic workflows or assays.
Project administration	Management and coordination responsibility for the research activity planning and execution.	Coordinating cross-institutional meetings; ethics compliance tracking; lab logistics.
Resources	Provision of study materials, reagents, materials, patients, or computational resources.	Providing cell lines, clinical patient cohorts, specialized hardware, or HPC clusters.
Software	Programming, software development; designing computer programs; testing code.	Writing Python/R scripts; maintaining GitHub repositories; building custom simulation tools.
Supervision	Oversight and leadership responsibility for research activity planning and execution.	Mentoring graduate students and postdocs; clinical direction; lab head oversight.
Validation	Verification of overall replication and reproducibility of results or experiments.	Independent blind replication of findings; running controls; verifying code outputs.
Visualization	Preparation, creation, and presentation of the published work (specifically data visualization).	Creating multi-panel figures; rendering 3D molecular models; designing schematics.
Writing – original draft	Creation and presentation of the published work, specifically writing the initial draft.	Authoring the initial manuscript narrative (Introduction, Results, Discussion).
Writing – review & editing	Critical review, commentary, or revision by those from the immediate research group.	Refining arguments; editing prose; responding to peer-review revisions.

Punctuation Syntax & Formatting Conventions

Publishers use automated text-mining scripts to extract contributor roles from your Word document and inject them into Crossref and PubMed Central XML metadata. To ensure automated parsers recognize your text, you must follow the Elsevier standard punctuation formula:

Author Name: Role 1, Role 2, Role 3. Next Author: Role 1, Role 4.

Essential Punctuation Rules:

Author Identity: Use full names (Jane Doe:) or initials (J.D.:) consistently. Full names are preferred by Elsevier; initials are standard in Nature.
Colon (:): Place a colon immediately after the author name or initials.
Comma (,): Separate multiple roles with a comma and a space.
Period (.): Place a period at the end of each author’s contribution string before starting the next author.
Hyphen vs. En-Dash in Writing Roles: The official NISO role title is Writing – original draft and Writing – review & editing with an en-dash (–) or spaced hyphen. Automated parsers accept both.

Publisher-Specific CRediT Implementation Differences

Different publishers format contributor statements under slightly varying headings:

Elsevier Journals: Mandates the exact heading CRediT authorship contribution statement. During submission in Editorial Manager, you will also be prompted to check corresponding contributor boxes for each co-author. See our Elsevier formatting guide.
Springer Nature & BioMed Central: Uses the heading Authors' contributions or Author contributions.bmc and SpringerOpen journals require full CRediT mapping. Consult our Springer Nature guidelines.
Wiley Journals: Uses Author Contributions. Wiley strongly encourages CRediT and supports automated ORCID-linked contributor attribution. Review our Wiley manuscript guidelines.
PLOS ONE: Authors enter contributor roles directly into Editorial Manager; PLOS compiles the statement automatically into the final proof under the CRediT standard. Check our PLOS ONE formatting guide.

Frequently Asked Questions (FAQ)

What is CRediT and why do academic journals require it?

CRediT (Contributor Roles Taxonomy) is a high-level standard formalized as ANSI/NISO Z39.104-2022. It replaces ambiguous author order with 14 standardized contributor roles. Journals require it to provide transparent attribution for individual scientific contributions, resolve credit allocation in multidisciplinary research, and eliminate honorary, guest, or ghost authorship.

Can an author be assigned multiple CRediT roles in the same paper?

Yes. Most academic authors perform several roles. For example, a doctoral student or postdoc frequently leads Conceptualization, Methodology, Investigation, Formal analysis, Visualization, and Writing – original draft, while a principal investigator may contribute to Conceptualization, Supervision, Project administration, Funding acquisition, and Writing – review & editing.

What is the difference between 'Writing – original draft' and 'Writing – review & editing'?

'Writing – original draft' refers to the primary creation and composition of the initial manuscript prose. 'Writing – review & editing' refers to critical review, commentary, revision, and intellectual refinement by other co-authors prior to or during peer review. All listed co-authors should typically be credited with at least 'Writing – review & editing'.

What punctuation syntax is required by Elsevier and Editorial Manager?

The accepted standard syntax uses author full names or initials followed by a colon, a comma-separated list of roles, and a period ending the entry. For example: 'Jane Doe: Conceptualization, Methodology, Writing – original draft. John Smith: Investigation, Software, Writing – review & editing.' Multiple authors are separated by a space and capitalized initials.

Where should the CRediT author statement be placed in a Word document?

In Microsoft Word, the CRediT author statement belongs in the back matter, typically under the heading 'CRediT authorship contribution statement' or 'Author Contributions', immediately before the Acknowledgments, Funding, or References section.
