There are many things to consider when deciding whether to review. It may help to ask yourself the following questions:
The time it takes to review an article varies depending on a number of factors, including:
In one 2008 study (1), the median time it took was about 5 hours, and the mean was about 9 hours.
Things that should be assessed in a review are:
Some journals will give clear instructions on what to cover, or will present you with a form to fill out as part of a review.
The format of the comments will depend on the journal you are reviewing for. Some journals accept in-document comments, while others use writing and editing software. Make sure to follow instructions for reviewers, if available, and quote line and page numbers when using evidence from the article.
The best place to find out about your duties and responsibilities as a peer reviewer is the website of the Committee on Publication Ethics , or COPE. You can also visit the section on this page called Ethics in peer review to find out more.

You can find out more about peer review models used in journals on the How to peer review journal articles page.
Editors may invite reviewers based on their own knowledge of the field, references in the article, through various searches with keywords, through journal or society databases, recommendations by the author or through industry tools. If you're interested in becoming a reviewer for a journal published by Cambridge, you can get in touch with with the editor for the relevant journal (you'll be able to find their name on the journal page) or email authorhub@cambridge.org .
Different journals have different policies about monitoring peer reviewers, but usually, yes, they do. Tools in submission systems can provide metrics on rejection rates to invitations to review, reviewer turnaround times, and time since the reviewer's last review.

In journals that allow co-reviewing, an invited reviewer can work with a more junior colleague to review a manuscript for the purpose of reviewer training. This allows the co-reviewer to gain experience with the review process and become a viable reviewer for a journal.
An invited reviewer can have a co-reviewer on a manuscript as long as the journal’s editorial office is made aware of this and approves the co-review. The invited reviewer will need to reach out to the journal’s editorial office about the co-reviewer when they accept the review. The co-reviewer must also declare any relevant conflicts of interest.
The co-reviewer must be specifically identified during the completion of the review, either in the ‘Confidential Comments to the Editor’ section or, if a journal has a specific question about co-review, in the reviewer report form. This allows the co-reviewer to be credited for the review and to be added to a journal’s reviewer pool.
All journal reviewers must follow the COPE ethical guidelines for peer reviewing at all times . Please see the additional Cambridge guidelines for peer review: A Guide to Peer Reviewing Journal Articles
