An author contribution statement for Frontiers is a mandatory, standardised disclosure — built on the CRediT taxonomy — that names each author’s initials against specific research tasks, placed just before the references. Because Frontiers also operates a collaborative, open peer review model in which reviewer identities are published alongside the article, that statement sits inside a visibly transparent record rather than behind a closed editorial process, raising the stakes for accuracy and completeness compared with journals that keep review closed.
The Contributor Roles Taxonomy (CRediT) is a structured set of 14 standardised labels — from Conceptualization to Writing – Review & Editing — used to describe what each named author actually did on a manuscript, replacing vague free-text authorship blurbs with a checkable, comparable record.

What does Frontiers require in an author contribution statement?
Frontiers’ author guidelines make the Author Contributions Statement mandatory for every submission across its journal portfolio, including titles operated under Frontiers Partnerships. The statement must represent all named authors, briefly describe individual tasks, and identify each person by initials rather than full names — with a middle initial added where two authors share the same first and last initials (for example, REW and RSW).
Practically, the submitting author enters each co-author’s contributions during the online submission process, and the system compiles them into the final statement, which is placed at the end of the manuscript, immediately before the References section. This mirrors the broader shift documented by publishers such as Elsevier and Wiley toward structured, submission-system-driven contribution capture rather than a free-text paragraph drafted after the fact.
Frontiers’ authorship threshold is explicitly anchored to the International Committee of Medical Journal Editors (ICMJE) criteria: substantial contribution to conception or design, data acquisition, analysis or interpretation; drafting or critically revising the work; final approval of the version to be published; and agreement to be accountable for all aspects of the work. A CRediT-tagged contribution statement does not replace this authorship test — it documents what qualifying authors did, once they already qualify.
What is CRediT, and where did it come from?
CASRAI originated the CRediT contributor role taxonomy in 2014, in collaboration with journal publishers and research funders seeking a shared vocabulary for describing authorship work. The standard is now stewarded by NISO as ANSI/NISO Z39.104-2022, which is the current authoritative specification of the 14 roles and their definitions.
Frontiers announced its adoption of CRediT on 20 July 2023, stating that the system “replaces the conventional free-text authorship descriptions with a standardized and transparent system that ensures consistency and accuracy in recognizing individual contributions.” Frontiers’ chief executive editor, Dr Frederick Fenter, framed the move as part of a wider commitment to openness within scholarly publishing.

Each role can be assigned to more than one author, and a single author can hold multiple roles — the taxonomy is designed to reflect real research teams, where contributions overlap rather than divide neatly by job title.
How does Frontiers’ open peer review model change the stakes?
Frontiers runs a collaborative review process in which reviewers interact directly with authors during revision and reviewer names are published on the final article. That design choice matters for contribution statements: in a closed-review journal, an inaccurate or vague CRediT statement is checked, at most, by an anonymous editor and reviewers whose identities never surface. At Frontiers, the same statement sits on a page where the reviewers who scrutinised the work are named too, creating a fuller, mutually visible accountability chain from idea to publication.
This does not mean reviewers audit CRediT tags line by line — Frontiers’ policy places that responsibility on the corresponding author — but it does mean the entire provenance record (who contributed what, and who reviewed it) is public and durable rather than partially hidden. For research integrity investigations, that visibility is a practical asset: a named reviewer trail alongside a role-based authorship record narrows the anonymity gap that closed models leave open.
| Feature | Traditional closed peer review | Frontiers’ collaborative open review |
|---|---|---|
| Reviewer identity | Anonymous to readers (and often to authors) | Published with the article |
| Author contribution statement | Visible to readers, but reviewed only by an anonymous editor | Visible to readers alongside named reviewers who assessed the work |
| Post-publication scrutiny | Contribution disputes are harder to trace to a specific review stage | Named reviewer record supports faster provenance checks |
| Incentive for precision | Lower — statement rarely cross-checked publicly | Higher — statement sits next to a public, named review record |
For research administrators advising on authorship disputes, this distinction is worth flagging explicitly: a Frontiers submission carries more public accountability infrastructure around a contribution statement than an equivalent closed-review journal, even though the CRediT taxonomy itself is identical across both.
What does a compliant example look like?
A CRediT-based Frontiers statement is typically compact — a handful of sentences, not a paragraph — and uses initials throughout. A representative, compliant format:
“AB: Conceptualization, Methodology, Writing – Original Draft. CD: Investigation, Formal Analysis, Visualization. EF: Data Curation, Software. GH: Supervision, Funding Acquisition. All authors contributed to the article and approved the submitted version.”
Three points distinguish a compliant statement from a weak one:
- Every named author appears at least once — omitting a listed author from the statement is a common submission-checklist rejection reason.
- Roles are drawn from the 14 standard CRediT labels, not invented descriptions (“helped with the project” is not a CRediT role).
- The closing sentence confirming collective approval is retained, satisfying the ICMJE’s fourth authorship criterion on accountability.
Common questions
What is a contribution statement example?
A contribution statement example lists each author’s initials against specific CRediT roles, such as “AB: Conceptualization, Writing – Original Draft.” It is a short, structured disclosure — typically two to five sentences — not a narrative account, and it appears at the end of the manuscript before the references.
How do I write an author contribution statement?
Assign each named author one or more of the 14 CRediT roles based on what they actually did, list contributions by initials, and add a closing line confirming all authors approved the submitted version. Frontiers’ online submission system compiles these entries automatically once authors provide them.
Do you have to pay to publish in Frontiers?
Yes — Frontiers is a gold open-access publisher and charges an article processing charge (APC) only after acceptance; no fee applies to rejected or withdrawn submissions. This fee transparency sits alongside the same openness principle that drives Frontiers’ published reviewer names and public contribution statements.
Implications for authors and institutions
Research offices advising authors on Frontiers submissions should treat the contribution statement as a document with two audiences at once: the editorial system checking ICMJE compliance, and a permanent public record sitting next to named reviewers. According to Frontiers Media’s own reporting on the Norwegian Scientific Index (NSD), 96 of its journals were listed in that register as of 2022 — a scale of output where standardised, auditable contribution data materially reduces the administrative burden of resolving authorship disputes after publication.
Institutions building CRediT literacy into researcher training should note that the taxonomy’s value compounds under open models: a precise, role-based statement becomes machine-readable metadata that can feed ORCID records, funder reporting, and institutional repositories, not just a line in a PDF.
Where this is heading
As more publishers combine structured contributorship data with visible review provenance, the author contribution statement stops being a compliance formality and becomes part of a public integrity record. Frontiers’ pairing of mandatory CRediT statements with named, published reviewers is one live example of that shift — and a template other open-review adopters are likely to follow as funders and institutions push for fuller contributorship transparency.
