Key Takeaways

Peer review is the process by which independent experts evaluate a manuscript’s validity, methodology, and significance before a journal accepts it for publication.
There are four widely used models of peer review: single blind, double blind, open, and post publication, each offering a different balance of anonymity and accountability.
Timelines vary considerably: most journals take anywhere from four weeks to six months to reach a first decision, depending on the field, journal tier, and reviewer availability.
Many manuscripts never reach peer review at all. They are desk rejected by an editor, usually because of poor fit, unclear writing, or formatting issues, rather than the quality of the underlying research.

What Is Peer Review?

Peer review is the process in which independent experts in a field assess a manuscript’s quality, validity, and significance before a journal decides whether to publish it. It acts as a checkpoint between a researcher’s draft and the published scientific record, ensuring that claims are supported by sound methodology and that findings add something meaningful to the field.

Nearly every reputable academic journal uses some form of peer review, though the exact model, timeline, and number of reviewers involved can differ significantly from one journal to another.

Why Peer Review Matters in Research

Peer review exists to protect the integrity of published research. It matters for several reasons:

Validation: subjecting a manuscript to expert scrutiny strengthens confidence in its findings and methodology.
Constructive feedback: reviewers often catch gaps in logic, missing controls, or unclear analysis that authors may have overlooked.
Quality control at scale: peer review filters out flawed methodology, unsupported claims, and, in rare cases, fraudulent data, before they reach readers.
Trust signal: funders, institutions, and other researchers use peer reviewed publication as a baseline marker of credibility when evaluating work.

The Peer Review Process: Step by Step

While details vary by journal, most peer review processes follow the same core stages.

Stage	What Happens
Submission	The author submits the completed manuscript to a journal, following its specific formatting and submission guidelines.
Editorial Evaluation	An editor checks whether the manuscript fits the journal’s scope, meets basic quality standards, and is ready to proceed.
Reviewer Assignment	The editor invites two or more independent experts in the manuscript’s subject area to review the work.
Peer Review	Reviewers evaluate the manuscript’s originality, methodology, data, and conclusions, usually over several weeks.
Reviewer Feedback	Reviewers submit written reports with a recommendation: accept, revise, or reject, along with detailed comments.
Revision	The author addresses reviewer comments, updates the manuscript, and prepares a point by point response letter.
Resubmission	The revised manuscript and response letter are sent back to the journal, and may go through another round of review.
Final Decision	The editor weighs the reviewers’ recommendations and the author’s revisions to issue a final publication decision.

Manuscript Submission System Explained

Here’s a reference table for the common manuscript status labels you’ll see in journal submission systems (ScholarOne, Editorial Manager, etc.). Exact wording varies by journal, but the stages map closely across platforms.

Status	What It Means	Editorial Manager	ScholarOne Manuscripts	OJS (Open Journal Systems)	How Long to Wait	Next Steps
Submitted / Awaiting Admin Processing	Manuscript received; automated checks running	“Submitted to Journal”	“Submitted”	“Submission”	3 to 5 business days	No action needed
With Editor / Awaiting Editor Assignment	Editor being assigned to handle the manuscript	“With Editor”	“Awaiting AE Assignment”	“Assigning Editor”	1 to 2 weeks	Wait
Editor Assigned / Awaiting Editor Decision	Handling editor doing initial read for scope and quality	“Editor Assigned” or “Editor Invited”	“Awaiting AE Recommendation”	“Assigned”	1 to 3 weeks	Wait, or a polite inquiry if delayed
Under Review / Reviewers Assigned	Reviewers evaluating the manuscript	“Under Review” or “Reviewers Assigned”	“Under Review”	“In Review”	4 to 12 weeks	Avoid contacting early
Required Reviews Completed	All reviewer reports are in	“Required Reviews Completed”	“Awaiting EIC Decision”	“Review Complete” or “Reviews Complete”	1 to 3 weeks	Wait
Decision in Process	Editor drafting the decision letter	“Decision in Process”	“Decision Pending”	“Decision Pending”	A few days to 1 week	No action needed
Minor Revision Requested	Small changes needed before acceptance	“Minor Revision”	“Minor Revision”	“Revisions Required”	2 to 4 weeks to resubmit	Address comments, resubmit
Major Revision Requested	Substantial changes needed before reconsideration	“Major Revision”	“Major Revision”	“Revisions Required”	4 to 8 weeks to resubmit	Revise thoroughly, request extension if needed
Revision Submitted	Revised manuscript sent back	“Revised Manuscript Submitted”	“Resubmitted”	“Revision Submitted”	2 to 6 weeks for next decision	Wait
Reject and Resubmit Invited	Declined as is; reworked version invited	“Reject and Resubmit”	“Reject and Resubmit”	Usually not a distinct status; handled as a new submission	No formal deadline	Treat as a new submission
Accepted	Approved for publication	“Accept”	“Accepted”	“Accepted”	Varies by production schedule	Await proofs, respond to queries
Rejected	Will not be published in this journal	“Reject”	“Decline” or “Reject”	“Declined”	Not applicable	Review feedback, consider another journal
Withdrawn	Author has pulled the manuscript	“Withdrawn by Author”	“Withdrawn”	“Withdrawn”	Not applicable	Confirm in writing before resubmitting elsewhere

A note on reliability: platform label text is configurable by each journal’s editorial office, so a journal on Editorial Manager or ScholarOne can technically relabel any of these statuses. The mappings above reflect the most common out-of-the-box defaults, not a universal standard.

A couple of practical notes worth keeping in mind:

When to actually email the journal: a polite status inquiry is generally acceptable once a manuscript has sat in one status well past the upper end of its typical range, not before.
“Under review” is usually the longest and most unpredictable stage since it depends on reviewer availability, not the journal’s internal speed.

Types of Peer Review Explained

Journals do not all follow the same review model. The four most common types differ mainly in who knows whose identity.

Type	Who Knows Whom	Best Suited For	Key Drawback
Single Blind	Reviewers know the author’s identity; authors do not know the reviewers.	The traditional default across most academic journals.	Can allow bias toward well known authors or prestigious institutions.
Double Blind	Neither authors nor reviewers know each other’s identity.	Fields where reducing bias tied to affiliation or reputation is a priority.	Anonymity is often incomplete, since writing style, citations, or datasets can reveal authorship.
Open	Both authors and reviewers know each other’s identity, and reports may be published alongside the article.	Journals that prioritize transparency and reviewer accountability.	Reviewers may hesitate to criticize senior or influential researchers openly.
Post Publication	Review and comment happen after the work is already public, often on preprint platforms.	Fast moving fields and preprint servers where speed matters.	Quality control depends on ongoing community engagement rather than a single formal gate.

How Long Does Peer Review Take?

Peer review typically takes between four weeks and six months from submission to a first decision, though the exact timeline depends on the field, the journal, and how quickly reviewers respond.

Journal or Field Type	Typical Time to First Decision	Typical Time to Publication
Fast track and open access journals	2 to 6 weeks	1 to 3 months
Mid tier specialty journals	6 to 12 weeks	3 to 6 months
High impact multidisciplinary journals	8 to 16 weeks	4 to 9 months
Clinical and medical journals with added ethics review	10 to 20 weeks	6 to 12 months

These ranges are general guidelines. Checking a target journal’s published turnaround statistics, when available, gives a more accurate estimate.

Understanding Editorial Decisions After Peer Review

Once reviewer reports are in, editors issue one of several standard decisions.

Decision	What It Means
Accept	The manuscript is ready for publication as is, or with only trivial copyediting changes.
Minor Revision	The core findings are sound, but small changes, such as clarifications, extra citations, or formatting fixes, are required.
Major Revision	Substantial changes to methodology, analysis, or framing are needed before the manuscript can be reconsidered.
Reject and Resubmit	The current version is not acceptable, but the editor invites a substantially reworked version as a new submission.
Reject	The manuscript will not be published in this journal, often due to scope, novelty, or fundamental methodological concerns.

Why Do Manuscripts Get Desk Rejected?

A desk rejection happens when an editor declines a manuscript before it ever reaches peer reviewers, usually within days rather than months. Common reasons include:

The topic falls outside the journal’s stated scope.
The writing is unclear, poorly organized, or contains significant English language errors.
The manuscript does not follow the journal’s formatting, length, or reference style guidelines.
The research lacks sufficient novelty or does not clearly state its contribution to the field.
Required elements are missing, such as ethical approval statements, data availability statements, or conflict of interest disclosures.

Peer Review Ethics and Integrity

Peer review depends on trust between authors, reviewers, and editors. Several integrity issues are worth understanding:

Conflicts of interest: reviewers with a personal, financial, or professional stake in a manuscript’s outcome are expected to decline the assignment.
Reviewer misconduct: this can include unreasonably delaying a review, using confidential material improperly, or appropriating ideas from an unpublished manuscript.
Fabricated peer review: some cases have involved authors manipulating the reviewer selection process to submit fake or self written reviews.
Confidentiality: manuscripts under review are treated as privileged information and should not be shared or discussed outside the review process.
Post publication checks: many journals now run plagiarism and image manipulation checks as a standard part of the integrity process, alongside human review.

How Are Peer Reviewers Selected?

Editors typically select reviewers based on their published expertise in the manuscript’s specific subfield, prior review history, and the absence of any conflict of interest with the authors.

Subject matter expertise: reviewers are matched to a manuscript’s specific methodology and subfield, not just its broad discipline.
Publication and review track record: editors favor reviewers with a history of publishing in the area and delivering timely, constructive reports.
Availability: many qualified experts decline review invitations due to time constraints, so editors often approach several reviewers before securing enough acceptances.
Author suggested reviewers: some journals allow authors to suggest potential reviewers during submission, though the editor decides whether to use them.
No conflict of interest: reviewers with close professional ties to the authors, such as recent co-authors or the same institution, are typically excluded.

The Growing Role of AI in Peer Review

Artificial intelligence tools are increasingly woven into the peer review workflow, though most journals still keep a human reviewer at the center of the decision.

Integrity screening: AI tools help detect plagiarism, duplicated images, and statistical anomalies before a manuscript reaches human reviewers.
Reviewer matching: some journals use AI to suggest suitable reviewers based on a manuscript’s subject matter and reviewer publication history.
Disclosure policies: a growing number of journals now require authors and reviewers to disclose any use of AI tools in preparing manuscripts or reviews.
Ongoing debate: questions remain about whether AI generated reviewer comments meet the same standard of accountability as human expert judgment.

Strengthening Your Manuscript Before Submission

Unclear language is one of the most common, and most avoidable, reasons a manuscript struggles at desk review or draws critical reviewer comments. Reviewers who have to work hard to decode a sentence are more likely to question the research behind it, even when the underlying work is sound.

Having a manuscript professionally edited before submission can reduce the risk of language related rejections and help reviewers focus on the science itself rather than the phrasing. Editage’s English editing services are built specifically for researchers preparing work for journal submission.

What Authors Can Do for Faster Peer Review

Authors cannot control reviewer speed directly, but a surprising amount of the timeline is shaped by decisions made before and during submission. Here is what actually moves the needle.

Before Submission

Choose a journal that matches scope tightly. A manuscript that clearly fits a journal’s stated aims and scope is less likely to sit in editorial evaluation or get desk rejected, which is the single biggest time-saver since it avoids a full resubmission cycle elsewhere.
Check the journal’s published turnaround data. Many journals report average time-to-first-decision on their “About” or “Instructions for Authors” pages. Picking a journal with a track record of fast, reliable review avoids gambling on an unusually slow one.
Follow formatting and reference style exactly. Manuscripts that need to be sent back for formatting fixes lose time before they even reach an editor.
Get a professional English edit if English is not your first language, or if the writing is dense. Editors and reviewers who struggle to parse a sentence are more likely to request revisions on clarity grounds, or desk reject outright. Services like Editage exist specifically to reduce this risk before submission.
Write a clear, focused cover letter. A cover letter that states the paper’s contribution in a few sentences helps the editor make a faster scope and significance judgment.

During Editor and Reviewer Assignment

Suggest qualified reviewers, if the journal allows it. Many systems let authors recommend reviewers during submission. Suggesting genuinely qualified experts (not close collaborators) can shorten the search for reviewers, which is often the slowest part of the whole process.
Flag non-preferred reviewers, if relevant. If there is a legitimate conflict of interest, excluding those individuals can prevent a review cycle from stalling with a reviewer who should not have been assigned in the first place.
Make data and code available upfront. If a data availability statement or repository link is required, having it ready avoids a back-and-forth request from the editor before review even starts.

While Under Review

Resist the urge to follow up too early. Under review is typically the longest stage and is driven by reviewer availability, not editorial delay. Premature inquiries rarely speed things up and can sometimes irritate an editor managing hundreds of manuscripts.
Respond quickly to any editor requests. If an editor asks for a missing form, clarification, or additional information mid-review, answering promptly prevents the file from sitting idle while waiting on the author.

During Revision

Treat revision deadlines as real deadlines. Late resubmissions can result in the manuscript being treated as a fresh submission, effectively restarting the clock.
Respond to every reviewer comment individually. A clear, point-by-point response letter reduces the chance of a second full review round, since vague or incomplete responses often prompt reviewers to ask for another look.
Do not over-argue minor points. Pushing back extensively on small, low-stakes comments can trigger additional review rounds; save firm pushback for points that genuinely affect the science.
Proofread the revised manuscript again. New language errors introduced during revision can create fresh delays, especially if the paper goes back to the same language-sensitive reviewer.

General Habits That Help Across the Whole Process

Track the manuscript status regularly, using the status table above, so you know when a stage has genuinely run long versus when it is still within normal range.
Keep communication professional and infrequent. One well-timed status inquiry after a stage has clearly overrun is far more effective than repeated check-ins.
Build in buffer time when planning around conferences, grants, or tenure deadlines. Peer review timelines are inherently variable, and planning around the optimistic end of the range is a common source of avoidable stress.

Frequently Asked Questions

How long does the peer review process take for a journal article?

Most journals take between four weeks and six months to reach a first decision, and often several more months after that to reach final publication. Fast track and open access journals tend to move faster, while high impact and clinical journals typically take longer due to added scrutiny and additional review rounds.

What is the difference between single blind and double blind peer review?

In single blind peer review, reviewers know who the authors are, but authors do not know who reviewed their work. In double blind peer review, neither party knows the other’s identity, which is intended to reduce bias based on an author’s reputation or institution, though complete anonymity is not always achievable.

Can a manuscript still be rejected after peer review has been completed?

Yes. Completing peer review does not guarantee acceptance. Editors can still reject a manuscript after review if reviewers raise serious concerns about validity, novelty, or methodology, or if the authors’ revisions do not adequately address those concerns.

What should I do if I receive a major revision request?

Treat a major revision request as a genuine opportunity rather than a rejection. Address every reviewer comment individually in a point by point response letter, make the corresponding changes in the manuscript, and clearly explain your reasoning wherever you respectfully disagree with a suggestion.

How many peer reviewers typically review one manuscript?

Most journals assign two to three independent reviewers per manuscript, though some fields or high stakes submissions may involve additional reviewers or a statistical reviewer if the editor has concerns about the data analysis.

What is a desk rejection, and how can I avoid one?

A desk rejection is an editor’s decision to reject a manuscript before it is sent out for peer review, often because of scope mismatch, unclear writing, or formatting issues. Carefully reviewing a journal’s aims and scope, following its author guidelines closely, and ensuring the writing is clear can significantly reduce this risk.

Is peer review the same thing as professional editing?

No, they serve different purposes. Peer review evaluates the scientific validity and significance of a manuscript, while professional editing improves language, clarity, and formatting before submission. Many authors use Editage’s English editing services ahead of submission specifically to reduce the chances that language issues distract reviewers from the substance of the research.

What happens when two peer reviewers disagree?

When reviewers reach different conclusions, the editor typically weighs both reports, considers their reasoning, and may invite a third reviewer to help resolve the disagreement. The final decision rests with the editor, not with either individual reviewer.

What do I do if a peer reviewer has misunderstood my study?

In your response letter, thank the reviewer for their comment, then clearly restate what your study actually did or claimed, pointing to the specific section, page, or line number where this is explained. If the misunderstanding is plausible, that is often a sign the manuscript itself needs to be clearer, so consider revising the relevant passage rather than only correcting the reviewer. Avoid language that suggests the reviewer was careless or wrong; frame it as an opportunity to sharpen the writing. Editors read these exchanges closely, and a respectful, evidence-based clarification tends to land far better than a defensive rebuttal, even when you are confident the reviewer simply misread the text.

What do I do if I find the peer reviewer comments rude or biased?

First, separate tone from substance. Reviewer comments can be blunt, even harsh, while still containing valid technical points worth addressing. Respond to the scientific content professionally in your revision letter, regardless of how it was delivered. If comments cross into personal, discriminatory, or clearly unprofessional territory rather than criticizing the work itself, it is appropriate to raise this directly with the handling editor in a separate, calm email, since editors are responsible for managing reviewer conduct. Most journals have policies against abusive review and will look into credible complaints. Avoid responding to the reviewer with matching hostility in your rebuttal letter, since that communication often becomes part of the editorial record and can affect how your revision is perceived.

What do I do if I cannot address the peer reviewers’ comments?

Not every comment can or should be implemented, and reviewers generally understand this. If a request is outside the scope of your study, requires data you do not have, or conflicts with your methodology for a defensible reason, say so directly in your response letter rather than ignoring the comment. Explain your reasoning with evidence: cite literature, describe a methodological constraint, or clarify why the suggested change would not improve the study. Editors expect some pushback and generally respect well-reasoned disagreement more than forced, superficial compliance. What matters is that every comment receives a response, even if that response is a respectful explanation of why no change was made, rather than silence.

What do I do if I can’t understand the peer reviewers’ comments?

If a comment is genuinely unclear, do not guess or ignore it. Reasonable options include asking your co-authors or colleagues in the field to interpret the comment, since a fresh set of eyes often catches an intended meaning you missed. If it remains unclear, you can address it as best you understand it in your response letter, while politely noting your interpretation, so the editor and reviewer can correct you if you read it wrong. In some cases, contacting the editorial office to ask for clarification on a specific comment is acceptable, though this should be reserved for genuinely ambiguous cases rather than routine questions.
