How can I search for courses that have a specific Certifying Agency for my CECs?

Go to the Courses (https://hub.ideafit.com/courses) section.
Click the Search (https://hub.ideafit.com/cec-search-results?search=) button or the View All Courses(https://hub.ideafit.com/cec-search-results) button above it.
The page will reload, and you will see the CEC Agencies section.
Select the Certifying Agency you are certifying with to view courses that offer their credits.
