The Certify & Route page includes the final compliance questions, a place to add information for the UW reviewers, and the ability to check for any remaining errors. Select Route to Reviewers to send your application to the reviewers. Once routed, you will see a Withdraw button. Use it to withdraw your application for editing. You would then re-route it with the changes.
The sections on the page vary depending on the application’s status and whether the person editing is the PI or not.
