If you submitted all required assignments in a course but don't see a Course Certificate on your Accomplishments page, you may not have fully completed the course. Check to make sure:
Your Name Verification or ID Verification has been approved.
Some courses require Name Verification before your Certificate is released. Others require ID Verification. To check, open your Account Settings page. If you see a link asking you to complete Name or ID Verification, click the link and follow the instructions to set up Name or ID Verification.
All your assignments have received grades, including peer-reviewed assignments.
It may take some time to receive a final grade from your peers; if you just submitted your assignment, check back in a few days. You also need to submit the required number of peer reviews for other learners in the course to get a grade.
You passed all required assignments, or you met the course passing threshold.
In most courses, you need a passing grade on all required assignments to get a Course Certificate. In cumulative graded courses, you need to meet the course passing threshold. Check the Grades tab to see your current course grade or check for are assignments you still need to pass.
