Click the green Upgrade to Verified button under the course on your edX dashboard or the Upgrade to Verified Certificate link on the right side of the course's Home tab inside of the course to access he payment form.
If these do not appear, then the upgrade deadline of your course has already passed or this coure does not offer certificates.
On the payment page enter your credit card information or click the PayPal button in the upper right to pay from your PayPal account. All fees are charged in US Dollars.
If this is your first upgrade, you will need to successfully verify your identity on edX. ID verification involves taking 2 photos using a webcam, one of your face, and one of a photo identification card that has your name and photo. For tips on how to do this successfully, see Best Practices for edX Photo Verification.
You can check the status of your verification via your dashboard. Approval generally takes 2-3 business days. You can start working in your course while the approval is pending.
Do I have to upgrade at the beginning?
You are welcome to begin a course in the audit track, then upgrade to the verified track soon after the course begins. We recommend upgrading as soon as possible so you can access the graded assignments needed to progress towards earning a certificate.
Note: You will not be able to upgrade to the verified track after the upgrade deadline has passed, or after the course has ended.
To find the specific deadline for your course, go to the course Home page, and then locate Verification Upgrade Deadline under Important Course Dates.
