If Performance Reviews are set up in your Academy, you can access yours easily and complete a self-review. No matter your job and role, finding this option follows the same path:
In the left navigation, make sure you are in the Learner Workspace.
When in the Learner Workspace, select Development -> Performance Reviews.
Under the My Reviews tab, find the incomplete review in question and click on the blue Review Now button.
Under the Reviews tab, you can start adding your review, the Holistic Dashboard is practically a quick view of your dashboard, and by clicking the "View profile" option, you can be redirected to your profile page where you can view all certificates/badges.
Click on the arrow next to the Performance Area, add a rating and a review, and don't forget to click Save when finished.
Repeat the same process for all performance areas and your review will be saved as draft. Once you have finalized your review, feel free to click on the Release button at the bottom of the page.
Please note that once you'll release your self-review, you won't be allowed to make any changes. The review will appear now as completed and you'll have only the option to view it and not to edit anything.
