PLOS ONE Submission Process

Most journals evaluate papers on significance and novelty. Editors ask: is this important enough for our readers? Will it change the field? PLOS ONE doesn't ask those questions. The editorial criteria are technical: Is the science sound? Are the methods appropriate? Are the conclusions supported by the data?

That's not a lower bar: it's a different bar. A paper with modest scope but rigorous methodology belongs in PLOS ONE. A paper with an ambitious hypothesis but underpowered statistics doesn't. If you misread PLOS ONE as a fallback journal where "anything goes," you'll get desk rejected for scope mismatch and never understand why.

The journal publishes across all disciplines: biology, medicine, chemistry, physics, social sciences, computational fields. It's intentionally discipline-agnostic. That means a rejection almost never comes down to field fit. It comes down to methodology and rigor.

When you submit, a PLOS ONE academic editor: typically a researcher in your field: does an initial desk review. This is not a quick skim. They look at specific things:

Methods and reproducibility. PLOS ONE has strict reporting requirements. Clinical trials need CONSORT compliance. Animal studies need ARRIVE compliance. Observational studies need STROBE. If your study type has a reporting checklist, you need to follow it. Missing compliance is one of the most common desk rejection triggers.

Statistical adequacy. Underpowered studies get flagged at the desk stage. If you ran a study with n=12 and claim significant results, expect pushback before external review even begins.

Data availability. PLOS ONE requires that supporting data be available to reviewers and readers. Proprietary datasets with no access statement, or data available "upon reasonable request" without a formal repository link, will slow your paper or get it rejected outright.

Ethics documentation. Human subjects research needs IRB approval documentation. Animal research needs IACUC or equivalent. These aren't optional: they're required fields in the submission system.

Software and code. If your analysis relies on custom code, you're expected to make it accessible. A GitHub link is fine. "Code available on request" is not.

PLOS ONE publishes detailed processing data. Here's what typical timelines look like:

Total time from submission to published article: 4-8 months for straightforward papers. Complex revisions can push 12+ months.

One PLOS ONE-specific timing factor: the academic editor assigned to your paper matters. PLOS ONE uses a large pool of editors across disciplines, and workload varies significantly. If your paper sits at desk review for more than 3 weeks with no action, you can email the editorial office to ask about status.

PLOS ONE sends papers to 2 external reviewers, occasionally 3. The review criteria mirror the desk review: they're not judging whether this is the most exciting paper of the year. They're assessing whether it's technically correct.

The structured review form asks reviewers to evaluate:

• Study design and statistical analysis: appropriate methods for the research question?

• Reporting of key results: complete and accurate presentation of findings?

• Discussion and conclusions: do they stay within what the data support?

• Adherence to reporting guidelines: are the appropriate checklists followed?

• Ethical compliance: proper documentation of approvals?

Reviewers are explicitly told NOT to reject based on perceived significance or expected citation impact. In practice, experienced PLOS ONE reviewers stick to this. You'll rarely get a rejection that says "this isn't novel enough." If you do, that's inappropriate and you can flag it to the editor.

Based on patterns across the literature and author reports, the most frequent PLOS ONE desk rejections fall into these categories:

Reporting guideline violations. CONSORT, STROBE, ARRIVE, PRISMA: missing or incomplete compliance is probably the single most common fixable rejection reason. Download the relevant checklist and fill it out completely before submission.

Inadequate statistical power. Small sample sizes without a priori power calculations, or post-hoc tests that don't account for multiple comparisons, consistently get flagged. If your study is exploratory by nature, frame it that way explicitly.

Missing data availability statement. Not just vague: PLOS ONE needs a specific statement about where data are deposited and how to access them. Figshare, Dryad, Zenodo, a journal supplement, or a GitHub repository all work. "Available on request" has been unacceptable since 2014.

Ethics statement issues. Missing IRB/IACUC number, incorrect committee name, or absent consent statement for human subjects work will trigger an immediate request or desk rejection.

Out-of-scope conclusions. If your abstract or discussion makes claims that go beyond what your data support, editors flag it. PLOS ONE reviewers are specifically trained to catch overreach.

The key shift when writing for PLOS ONE is to make your rigor visible. Don't bury methodological decisions in the methods section: explain them. If you chose a sample size for a specific reason, say so. If you pre-registered the study, link to it prominently.

For the abstract, structure it tightly: background, objective, methods summary, key results (with numbers), and conclusion. PLOS ONE abstracts are indexed and read in isolation: make every sentence count.

For the discussion, stay close to your data. The PLOS ONE reviewer's checklist includes a specific item about whether conclusions are supported by the presented results. If you extrapolate significantly, expect a revision request.

For figures, PLOS ONE has specific formatting requirements (TIFF/EPS, minimum 300 DPI for halftones). Submit production-ready figures the first time. Reformatting after acceptance delays publication.

PLOS ONE's APC is $2,477 USD. This applies to all accepted papers. PLOS has institutional agreements with many universities that reduce or eliminate this cost: check the PLOS institutional account program before worrying about paying out of pocket. Many authors at US and European institutions pay nothing.

For authors without institutional support, PLOS ONE offers fee assistance and waivers. The waiver process is straightforward and based on self-reported financial need. If cost is an issue, apply: the journal approves most waiver requests.

PLOS ONE's data policy is stricter than most journals, and it trips up authors who aren't prepared. The requirement is straightforward: all data underlying the findings must be fully available without restriction at the time of publication. "Available upon reasonable request" hasn't been acceptable since 2014. Here's what that means in practice.

The exception pathway exists but it's narrow. If your data genuinely can't be shared publicly, patient-identifiable information, indigenous community data with restricted governance, or data owned by a third party, you must explain this in your Data Availability Statement and provide a contact point for access requests. PLOS ONE's editors review these exceptions case by case. Weak justifications ("our institution doesn't allow it") get rejected. Strong justifications ("data contain identifiable patient information; de-identified datasets are available from [specific contact]") get approved.

Prepare your data availability statement before you write the paper, not after acceptance. Depositing data in a public repository takes time, especially if your institution has data governance requirements.

Most PLOS ONE papers don't get accepted on the first round. The typical path is one to two revision rounds, with a small percentage requiring three. Understanding what each round usually involves helps you budget time and avoid unnecessary delays.

The most common revision requests follow predictable patterns. Statistical concerns top the list: missing power calculations, inappropriate tests for the data type, or uncorrected multiple comparisons. Methods detail is second, PLOS ONE's reproducibility standard means reviewers want enough information to replicate your exact procedure. Reporting checklist compliance is third, especially for clinical or animal studies where CONSORT, STROBE, or ARRIVE checklists are required.

How to respond efficiently: create a response document with numbered entries matching each reviewer comment. Quote the comment, state what you changed, and give the exact page/line numbers. Don't argue with reviewers unless they're factually wrong, if a reviewer asks you to justify a statistical choice, justify it rather than explaining why the question is unnecessary. Academic Editors read the response letter as carefully as the revised manuscript. A clear, systematic response that addresses every point (even minor ones) signals professionalism and usually leads to faster acceptance.

A PLOS ONE submission readiness check can identify the statistical, methods, and reporting issues that PLOS ONE reviewers most commonly flag.

In our pre-submission review work with manuscripts targeting PLOS ONE, three patterns generate the most consistent desk rejections among the papers we analyze.

Reporting guideline checklists that are incomplete or submitted without the checklist item numbers in the manuscript. PLOS ONE requires CONSORT for randomized controlled trials, STROBE for observational studies, ARRIVE for animal research, and PRISMA for systematic reviews. We see consistent desk rejection of papers where the checklist is submitted as a PDF with items marked "yes" but where the manuscript itself does not include the specific methodological elements those items require. An academic editor checking CONSORT item 17 (subgroup analyses) will look for pre-specified subgroup analysis in the methods section and the statistical analysis plan, not just for a checkmark indicating the authors believe they met the requirement. Incomplete alignment between the checklist and the manuscript text is the most fixable desk rejection cause at PLOS ONE, and the most common.

Data availability statements that reference restricted-access repositories or use "available upon request." PLOS ONE's data policy requires that all data underlying the published findings be fully available without restriction at the time of publication. We observe that many submissions include data availability statements that describe data as available through institutional repositories with access controls, through commercial data licenses, or upon request to the corresponding author. The journal's editors have been rejecting these statements since 2014, and the policy is consistently enforced. The only acceptable exceptions are patient-identifiable data and third-party-owned data with documented governance restrictions, and even those require a specific named contact for data access, not a generic "contact corresponding author" clause.

Sample sizes that are not justified with a priori power calculations. We see consistent reviewer pushback, and some desk rejections, on manuscripts where the sample size is small and no power analysis or sample-size justification appears in the methods section. PLOS ONE does not require that studies be large. It requires that the sample size be appropriate and justified for the question being asked. A study with n=15 per group can pass PLOS ONE review if the power calculation is presented and the research question supports this design. The same study without a power calculation, or with a post-hoc power calculation inserted after results were collected, consistently draws reviewer concern that the study is underpowered for its stated conclusions.

SciRev author-reported data confirms PLOS ONE's approximately 42-day median to first decision. A PLOS ONE submission readiness check can check whether your reporting checklist alignment, data availability statement, and statistical power documentation meet PLOS ONE's desk-review standard before you upload.
