Go to "My assessments," select the relevant assessment, then click on the candidate you want to rate.
On the candidate's results page, scroll down to the list of his or her answers to your custom questions. By clicking the icon in the "View answer" column, you'll be able to view the detailed answer for each question.
After reviewing an answer, click on a star rating to rate it. If you want to give a rating of 4 out of 5, for instance, you'd click the fourth star from the left.
