ICMJE Authorship Criteria
Also known as: ICMJE Authorship, Authorship Guidelines
The International Committee of Medical Journal Editors (ICMJE) established the most widely adopted authorship standard in biomedical research in 1978. These criteria define who qualifies as an author and distinguish authors from contributors, establishing accountability and preventing disputes over publication credit. Used by over 10,000 journals globally, ICMJE authorship criteria form the foundation of authorship practices in medical, life science, and health-related research.
Key highlights
- Internationally standardized and recognized by 10,000+ journals, eliminating ambiguity across different publishing contexts.
- Operationally clear—four concrete requirements eliminate subjective judgments about 'significance' of contribution.
- Protects authors by requiring accountability; an author cannot later disavow responsibility for the work.
- Reduces authorship disputes by forcing explicit discussion early in the project.

When to use it
Apply ICMJE criteria at the start of any research project, especially those involving multiple researchers. Use these criteria when writing a manuscript intended for publication in a biomedical or clinical journal. Review criteria before manuscript submission to ensure all authors agree and no disputes will arise. Use them as a basis for institutional authorship policies. Apply to thesis committees to clarify supervisor vs. student author status.
Strengths & limitations
- Internationally standardized and recognized by 10,000+ journals, eliminating ambiguity across different publishing contexts.
- Operationally clear—four concrete requirements eliminate subjective judgments about 'significance' of contribution.
- Protects authors by requiring accountability; an author cannot later disavow responsibility for the work.
- Reduces authorship disputes by forcing explicit discussion early in the project.
- The four criteria can be interpreted flexibly, especially criterion 1 ('substantial contribution'—no minimum threshold defined).
- Does not address relative weighting of contributions (first author vs. middle author).
- Does not resolve situations where multiple people contribute equally or where roles overlap.
- Some fields (e.g., large physics collaborations, field ecology) have adapted ICMJE criteria in discipline-specific ways.

Frequently asked
Does providing funding or equipment make someone an author?
No. Providing funding, materials, or lab space does not meet ICMJE criteria unless that person also contributed intellectually to conception, design, data analysis, drafting, revision, or approval. Such contributors are listed in Acknowledgments, not as authors.
Can a supervisor always be an author on a student's work?
Only if the supervisor meets all four criteria. If the supervisor designed the study and critically revised the manuscript, yes. If they only provided oversight or laboratory facilities, they should be acknowledged but not listed as an author.
What if team members contributed equally—how should we list authors?
All co-equal authors must meet the same four criteria. The author order is a convention issue (not addressed by ICMJE) and is decided by the research team. Some journals allow a footnote stating 'these authors contributed equally.' Order does not determine authorship validity.
If I disagree about authorship, what should I do?
Document your concern in writing to the corresponding author and journal editor before submission. If unresolved, contact your institution's research integrity office. Many journals will not process a manuscript if authorship is disputed.
Can an author be removed after publication?
Yes, but it is rare and requires all remaining authors' agreement and explanation. The journal publishes a correction or retraction notice. This is different from a formal retraction (which invalidates the entire paper) and signals serious authorship misconduct.
