If you would like to reassign a CARA Approval from one Student-Athlete to another, you can do this from either the Time Management > Cara Approval page or the Time Management > Submitted Logs pages.
Click on the "Pending Approvals" link and a page will pop up with the list of pending approvals and options to either send them a reminder email or reassign the approval.
When you click the reassign button, you will be prompted to search for other Student-Athletes associated with that roster, and you can select the one you want to move the task to, and hit reassign in the bottom right.
