Can I reopen the evaluation of individual students?

Yes, you can! Assuming you haven't locked or released the results yet. If you did lock the results, you have to unlock the evaluation first.

Go to your evaluation results where you see all students in a table. On the left of each student is a checkbox. Select each student evaluation you want to reopen and select Reopen from the buttons that appear at the top of the page. Optionally tune the email text and click Send.

Students will directly receive the email. With the link in it, they can double-check or adjust their evaluation and submit it again.
