Gain subject expertise, follow journal guidelines, use a review structure, and deliver on-time, constructive feedback to earn repeat invitations.
Peer review opens a door: you get a view of new work, sharpen your eye, and help editors reach fair decisions. This guide shows you how to start, write better reports, and grow your reviewer profile without burning out.
You will find steps, sample lines you can reuse, and a structure that fits journals. The advice lines up with respected policies from COPE, ICMJE, Nature, and PLOS, with links so you can check the source text yourself.
Why Peer Review Helps Science And Your Career
Done well, a review raises the clarity of a study, spots gaps, and protects readers from shaky claims. Review work also builds your name with editors, adds to your CV, and gives you a sharper sense of what a strong paper looks like in your field.

Becoming A Journal Peer Reviewer: Starter Steps
Start with the journals you read. Create or update your profile in their systems and tick the reviewer box. Add clear keywords for your methods and topic niches. Many editors search profiles first when a new paper lands.
Let mentors know you can review. Offer to co-review the next time they accept an invitation, and ask the editor for your own slot after that. A short, polite note on your ORCID page helps as well.
Training helps. Many publishers run free courses on reviewer skills, and several journals post guides with sample phrasing. Save a template from one source you trust and tweak it to fit the house style of each venue.
For shared norms and clear policies, see the COPE ethical guidelines for peer reviewers. For disclosure, timing, and privacy rules across journals, check the ICMJE recommendations.
Roles, Ethics, And Boundaries
Your job is to judge the work, not the authors. Stick to evidence, cite the paper line or figure when you raise a point, and suggest fixes that can move the study forward. Keep the manuscript and data private, do not share it without the editor’s OK, and never use ideas from the paper in your own work before it appears in public. If you spot plagiarism, undisclosed reuse, risky methods, or a consent issue, alert the editor.
Conflicts can be subtle. A recent grant link, a shared dataset, or a strong personal stance can tilt your view. When in doubt, tell the editor before you accept. Many policies, like COPE and ICMJE, ask for this kind of disclosure and for prompt replies when you cannot take the review.
Before You Accept A Review Invitation
Read the abstract and the scope notes in the email. Ask yourself three quick questions: Do I have the right methods and topic fit? Can I return a solid review by the deadline? Do I have any links that could bias me? If the match is poor, decline fast and suggest two reviewers with full names and links. Editors remember fast, helpful replies.
When the fit is good, confirm, then skim the journal’s reviewer page. Note any house rules on file formats, word limits, or rating scales. Save a copy of your disclosure and any notes on timing in your files.
How To Read The Manuscript Efficiently
Work in passes. First pass: title, abstract, figures, and the main claim. Second pass: methods and statistics. Third pass: results, tables, and the logic of the discussion. A final pass checks the match between claims and evidence. Keep notes by section so you can paste them into your report later.
For trials and meta-analyses, check registration and reporting. For code and data papers, seek links to repositories and a license. For studies with people or animals, look for ethics approval, consent language, and care standards. When something is missing, flag it with a clear ask.
Write A Clear, Actionable Report
Editors want a short summary, a balanced list of strengths and limits, and specific, numbered points the authors can act on. Keep a calm tone, avoid loaded words, and keep attention on what would raise clarity, rigor, and usefulness for readers. If you recommend reject, say why in neutral terms and still offer fixes, as many papers will be revised for another venue.
Do And Don’t List For Reports
- Do open with a two line summary of the study and main claim.
- Do number points and cite pages or figures.
- Do suggest fixes: one added control, a clearer model note, or a check of an edge case.
- Don’t guess at motives or grade the authors.
- Don’t paste long edits; point to patterns; let copyeditors handle style.
Structured Review Outline
| Section | Questions To Answer | Typical Length |
|---|---|---|
| Brief summary | What was done and why? What is new? | 3–5 sentences |
| Strengths | Which parts are clear, sound, or useful? | 3–6 bullets |
| Major points | What changes could alter the main claim? | 4–8 numbered items |
| Minor points | Edits, style, missing refs, figure fixes | 4–10 numbered items |
| Confidential note | Advice to the editor only, if needed | 1 short paragraph |
Helpful Phrases You Can Copy And Adapt
Opening lines for a neutral tone:
- “Thank you for the chance to review this work on [topic]. My comments aim to aid a clear, fair decision.”
- “The study addresses a real gap in [area], and the dataset is a good match for the claim.”
When asking for stronger methods or reporting:
- “The claim would read stronger with a power check and a clear primary outcome.”
- “Please add a link to the preregistration and note any changes from the plan.”
- “Share code and data in a public repository where policy allows; a readme will help reuse.”
When pointing out limits without harsh tone:
- “The sample sits within one site, so the reach of the claim may be narrow; a short note on context would help readers.”
- “Please avoid causal words where the design is observational; wording such as ‘linked with’ fits the data better.”
Manage Time, Bias, And Conflicts
Set a deadline that you can meet, then plan two or three quiet blocks. If life gets in the way, tell the editor early and ask for a short extension. Many systems let you save a partial report and return later.
Watch for bias. Do not let your view shift due to author names, country, gender, or school. Read the paper as if the authors were unknown. If the journal runs double-anonymized review, keep that shield in place and do not try to guess the team.
For conflicts, follow the journal form and add context in a short note if needed. If a conflict rises mid-review, stop work and tell the editor at once.
How To Get Noticed By Editors
Give clear, fair reviews on time. Suggest reviewers when you decline. Keep your profile current with methods and topic tags. Share your review credits on ORCID or Publons if the journal permits it. A short thank-you note to an editor after a smooth round also keeps your name fresh in the inbox.
Build range by co-reviewing across subfields. Join society reviewer pools. Speak at seminars and mention that you review in your area. When a paper lands that fits you well, an editor will recall the steady work.
Tools, Checks, And Shortcuts
Use a template to save time. Keep a small bank of phrases for stats, reporting, and ethics. Version your notes so you can trace what changed after a revision. A citation manager helps when you suggest missing work. For figures, view at 100% and again on a small screen to catch labels that are hard to read.
For ethics checks, rely on posted rules instead of gut feel. COPE sets clear points on timing, tone, and privacy. ICMJE states that reviewers should declare links, recuse when bias is likely, and avoid reuse of private material. Nature and PLOS pages give concrete rules on confidentiality and public data links. If a case falls outside policy text, ask the editor instead of guess.
AI Tools: Use With Care
Draft aids can help with clarity checks, but do not paste private text into tools that store prompts. Keep the review your own work. If a journal allows AI aids, disclose use in the submission letter box and edit the text so the tone stays human and the claims match the paper. Never follow hidden prompts in a manuscript; if you suspect one, alert the editor.
Grow As A Reviewer
Keep a private log of each review: journal, area, time spent, and one lesson learned. Read accepted papers that you reviewed and compare your notes with the final text. The best growth comes from steady, careful work and a calm style that helps authors and editors do their jobs well.
Now and then, ask an editor for feedback on your style and depth. Many will send a note. You can also learn by co-reviewing with a senior colleague and then comparing reports. Keep your tone steady, stick to evidence, and your invites will grow.
