How to Write a Peer Review

When you write a peer review for a manuscript, what should you include in your comments? What should you leave out? And how should the review be formatted?

This guide provides quick tips for writing and organizing your reviewer report.

Review Outline

Use an outline for your reviewer report so it’s easy for the editors and author to follow. This will also help you keep your comments organized.

Think about structuring your review like an inverted pyramid. Put the most important information at the top, followed by details and examples in the center, and any additional points at the very bottom.

Here’s how your outline might look:

1. Summary of the research and your overall impression

In your own words, summarize what the manuscript claims to report. This shows the editor how you interpreted the manuscript and will highlight any major differences in perspective between you and the other reviewers. Give an overview of the manuscript’s strengths and weaknesses. Think about this as your “take-home” message for the editors. End this section with your recommended course of action.

2. Discussion of specific areas for improvement

It’s helpful to divide this section into two parts: one for major issues and one for minor issues. Within each section, you can talk about the biggest issues first or go systematically figure-by-figure or claim-by-claim. Number each item so that your points are easy to follow (this will also make it easier for the authors to respond to each point). Refer to specific lines, pages, sections, or figure and table numbers so the authors (and editors) know exactly what you’re talking about.

Major vs. minor issues

What’s the difference between a major and minor issue? Major issues should consist of the essential points the authors need to address before the manuscript can proceed. Make sure you focus on what is  fundamental for the current study . In other words, it’s not helpful to recommend additional work that would be considered the “next step” in the study. Minor issues are still important but typically will not affect the overall conclusions of the manuscript. Here are some examples of what would might go in the “minor” category:

• Missing references (but depending on what is missing, this could also be a major issue)
• Technical clarifications (e.g., the authors should clarify how a reagent works)
• Data presentation (e.g., the authors should present p-values differently)
• Typos, spelling, grammar, and phrasing issues

3. Any other points

Confidential comments for the editors.

Some journals have a space for reviewers to enter confidential comments about the manuscript. Use this space to mention concerns about the submission that you’d want the editors to consider before sharing your feedback with the authors, such as concerns about ethical guidelines or language quality. Any serious issues should be raised directly and immediately with the journal as well.

This section is also where you will disclose any potentially competing interests, and mention whether you’re willing to look at a revised version of the manuscript.

Do not use this space to critique the manuscript, since comments entered here will not be passed along to the authors.  If you’re not sure what should go in the confidential comments, read the reviewer instructions or check with the journal first before submitting your review. If you are reviewing for a journal that does not offer a space for confidential comments, consider writing to the editorial office directly with your concerns.

Giving Feedback

Giving feedback is hard. Giving effective feedback can be even more challenging. Remember that your ultimate goal is to discuss what the authors would need to do in order to qualify for publication. The point is not to nitpick every piece of the manuscript. Your focus should be on providing constructive and critical feedback that the authors can use to improve their study.

If you’ve ever had your own work reviewed, you already know that it’s not always easy to receive feedback. Follow the golden rule: Write the type of review you’d want to receive if you were the author. Even if you decide not to identify yourself in the review, you should write comments that you would be comfortable signing your name to.

In your comments, use phrases like “ the authors’ discussion of X” instead of “ your discussion of X .” This will depersonalize the feedback and keep the focus on the manuscript instead of the authors.

General guidelines for effective feedback

• Justify your recommendation with concrete evidence and specific examples.
• Be specific so the authors know what they need to do to improve.
• Be thorough. This might be the only time you read the manuscript.
• Be professional and respectful. The authors will be reading these comments too.
• Remember to say what you liked about the manuscript!

Don’t

• Recommend additional experiments or  unnecessary elements that are out of scope for the study or for the journal criteria.
• Tell the authors exactly how to revise their manuscript—you don’t need to do their work for them.
• Use the review to promote your own research or hypotheses.
• Focus on typos and grammar. If the manuscript needs significant editing for language and writing quality, just mention this in your comments.
• Submit your review without proofreading it and checking everything one more time.

Before and After: Sample Reviewer Comments

Keeping in mind the guidelines above, how do you put your thoughts into words? Here are some sample “before” and “after” reviewer comments

✗ Before

“The authors appear to have no idea what they are talking about. I don’t think they have read any of the literature on this topic.”

✓ After

“The study fails to address how the findings relate to previous research in this area. The authors should rewrite their Introduction and Discussion to reference the related literature, especially recently published work such as Darwin et al.”

“The writing is so bad, it is practically unreadable. I could barely bring myself to finish it.”

“While the study appears to be sound, the language is unclear, making it difficult to follow. I advise the authors work with a writing coach or copyeditor to improve the flow and readability of the text.”

“It’s obvious that this type of experiment should have been included. I have no idea why the authors didn’t use it. This is a big mistake.”

“The authors are off to a good start, however, this study requires additional experiments, particularly [type of experiment]. Alternatively, the authors should include more information that clarifies and justifies their choice of methods.”

Suggested Language for Tricky Situations

You might find yourself in a situation where you’re not sure how to explain the problem or provide feedback in a constructive and respectful way. Here is some suggested language for common issues you might experience.

What you think : The manuscript is fatally flawed. What you could say: “The study does not appear to be sound” or “the authors have missed something crucial”.

What you think : You don’t completely understand the manuscript. What you could say : “The authors should clarify the following sections to avoid confusion…”

What you think : The technical details don’t make sense. What you could say : “The technical details should be expanded and clarified to ensure that readers understand exactly what the researchers studied.”

What you think: The writing is terrible. What you could say : “The authors should revise the language to improve readability.”

What you think : The authors have over-interpreted the findings. What you could say : “The authors aim to demonstrate [XYZ], however, the data does not fully support this conclusion. Specifically…”

Time to Submit the Review!

Be sure you turn in your report on time. Need an extension? Tell the journal so that they know what to expect. If you need a lot of extra time, the journal might need to contact other reviewers or notify the author about the delay.

Tip: Building a relationship with an editor

You’ll be more likely to be asked to review again if you provide high-quality feedback and if you turn in the review on time. Especially if it’s your first review for a journal, it’s important to show that you are reliable. Prove yourself once and you’ll get asked to review again!

How to Review a Journal Article

• Request Info Request info for....     Undergraduate/Graduate     Online     Study Away     Continuing & Professional Education     International Student Services     General Inquiries

For many kinds of assignments, like a  literature review , you may be asked to offer a critique or review of a journal article. This is an opportunity for you as a scholar to offer your  qualified opinion  and  evaluation  of how another scholar has composed their article, argument, and research. That means you will be expected to go beyond a simple  summary  of the article and evaluate it on a deeper level. As a college student, this might sound intimidating. However, as you engage with the research process, you are becoming immersed in a particular topic, and your insights about the way that topic is presented are valuable and can contribute to the overall conversation surrounding your topic.

IMPORTANT NOTE!!

Some disciplines, like Criminal Justice, may only want you to summarize the article without including your opinion or evaluation. If your assignment is to summarize the article only, please see our literature review handout.

Before getting started on the critique, it is important to review the article thoroughly and critically. To do this, we recommend take notes,  annotating , and reading the article several times before critiquing. As you read, be sure to note important items like the thesis, purpose, research questions, hypotheses, methods, evidence, key findings, major conclusions, tone, and publication information. Depending on your writing context, some of these items may not be applicable.

Questions to Consider

To evaluate a source, consider some of the following questions. They are broken down into different categories, but answering these questions will help you consider what areas to examine. With each category, we recommend identifying the strengths and weaknesses in each since that is a critical part of evaluation.

Evaluating Purpose and Argument

• How well is the purpose made clear in the introduction through background/context and thesis?
• How well does the abstract represent and summarize the article’s major points and argument?
• How well does the objective of the experiment or of the observation fill a need for the field?
• How well is the argument/purpose articulated and discussed throughout the body of the text?
• How well does the discussion maintain cohesion?

Evaluating the Presentation/Organization of Information

• How appropriate and clear is the title of the article?
• Where could the author have benefited from expanding, condensing, or omitting ideas?
• How clear are the author’s statements? Challenge ambiguous statements.
• What underlying assumptions does the author have, and how does this affect the credibility or clarity of their article?
• How objective is the author in his or her discussion of the topic?
• How well does the organization fit the article’s purpose and articulate key goals?

Evaluating Methods

• How appropriate are the study design and methods for the purposes of the study?
• How detailed are the methods being described? Is the author leaving out important steps or considerations?
• Have the procedures been presented in enough detail to enable the reader to duplicate them?

Evaluating Data

• Scan and spot-check calculations. Are the statistical methods appropriate?
• Do you find any content repeated or duplicated?
• How many errors of fact and interpretation does the author include? (You can check on this by looking up the references the author cites).
• What pertinent literature has the author cited, and have they used this literature appropriately?

Following, we have an example of a summary and an evaluation of a research article. Note that in most literature review contexts, the summary and evaluation would be much shorter. This extended example shows the different ways a student can critique and write about an article.

Chik, A. (2012). Digital gameplay for autonomous foreign language learning: Gamers’ and language teachers’ perspectives. In H. Reinders (ed.),  Digital games in language learning and teaching  (pp. 95-114). Eastbourne, UK: Palgrave Macmillan.

Be sure to include the full citation either in a reference page or near your evaluation if writing an  annotated bibliography .

In Chik’s article “Digital Gameplay for Autonomous Foreign Language Learning: Gamers’ and Teachers’ Perspectives”, she explores the ways in which “digital gamers manage gaming and gaming-related activities to assume autonomy in their foreign language learning,” (96) which is presented in contrast to how teachers view the “pedagogical potential” of gaming. The research was described as an “umbrella project” consisting of two parts. The first part examined 34 language teachers’ perspectives who had limited experience with gaming (only five stated they played games regularly) (99). Their data was recorded through a survey, class discussion, and a seven-day gaming trial done by six teachers who recorded their reflections through personal blog posts. The second part explored undergraduate gaming habits of ten Hong Kong students who were regular gamers. Their habits were recorded through language learning histories, videotaped gaming sessions, blog entries of gaming practices, group discussion sessions, stimulated recall sessions on gaming videos, interviews with other gamers, and posts from online discussion forums. The research shows that while students recognize the educational potential of games and have seen benefits of it in their lives, the instructors overall do not see the positive impacts of gaming on foreign language learning.

The summary includes the article’s purpose, methods, results, discussion, and citations when necessary.

This article did a good job representing the undergraduate gamers’ voices through extended quotes and stories. Particularly for the data collection of the undergraduate gamers, there were many opportunities for an in-depth examination of their gaming practices and histories. However, the representation of the teachers in this study was very uneven when compared to the students. Not only were teachers labeled as numbers while the students picked out their own pseudonyms, but also when viewing the data collection, the undergraduate students were more closely examined in comparison to the teachers in the study. While the students have fifteen extended quotes describing their experiences in their research section, the teachers only have two of these instances in their section, which shows just how imbalanced the study is when presenting instructor voices.

Some research methods, like the recorded gaming sessions, were only used with students whereas teachers were only asked to blog about their gaming experiences. This creates a richer narrative for the students while also failing to give instructors the chance to have more nuanced perspectives. This lack of nuance also stems from the emphasis of the non-gamer teachers over the gamer teachers. The non-gamer teachers’ perspectives provide a stark contrast to the undergraduate gamer experiences and fits neatly with the narrative of teachers not valuing gaming as an educational tool. However, the study mentioned five teachers that were regular gamers whose perspectives are left to a short section at the end of the presentation of the teachers’ results. This was an opportunity to give the teacher group a more complex story, and the opportunity was entirely missed.

Additionally, the context of this study was not entirely clear. The instructors were recruited through a master’s level course, but the content of the course and the institution’s background is not discussed. Understanding this context helps us understand the course’s purpose(s) and how those purposes may have influenced the ways in which these teachers interpreted and saw games. It was also unclear how Chik was connected to this masters’ class and to the students. Why these particular teachers and students were recruited was not explicitly defined and also has the potential to skew results in a particular direction.

Overall, I was inclined to agree with the idea that students can benefit from language acquisition through gaming while instructors may not see the instructional value, but I believe the way the research was conducted and portrayed in this article made it very difficult to support Chik’s specific findings.

Some professors like you to begin an evaluation with something positive but isn’t always necessary.

The evaluation is clearly organized and uses transitional phrases when moving to a new topic.

This evaluation includes a summative statement that gives the overall impression of the article at the end, but this can also be placed at the beginning of the evaluation.

This evaluation mainly discusses the representation of data and methods. However, other areas, like organization, are open to critique.
