All courses on the Web of Science Academy results in a certificate once successfully completed. Completing the 'Co-reviewing with a mentor' course earns you an Academy graduate badge (see below) on your Publons profile as long as the email you are using in the Web of Science Academy is associated with your Publons account. 

To complete the 'Co-reviewing with a mentor course' you need to complete a co-review assignment together with a mentor (either your own or a community mentor), and submit a filled out peer review report form as your assignment. The quality of the review needs to meet minimum requirements of what constitutes a peer review (summary statement, impact statement, and at least one suggestion for the authors of what they can do to improve their manuscript), and ideally show that you have learnt something from the course and that you have incorporated feedback from your mentor.
