After you complete a CE class module you will be required to enter your license number on your class dashboard, and e-sign the certification that you completed the courses on your own.
After you complete the certification your completion certificate will be made available shortly, and you will be able to download your certificate of completion on your courses page by clicking on the Completion Certificates option.
Please keep in mind that you'll need to repeat this process for each course completed. Also, please note that CE certificates are only valid for 2 years from the date of your course completion, and you should only use valid certificates for your license renewal.
