Another member, Christine, posted the answer to this a few threads below, so I’m just copying and pasting her answer. Thanks, Christine!
“I have found two ways. One, when you first log in to IDEA on your home page there are a number of blue boxes to the right and under your information. See the box for free CEUs.
Or, from the top of the page, if you go to My Account, you will be on Overview. Scroll over to the right and find My Education. I believe you can scroll down and choose from a number of free courses.”
Personally, I’ve used the second method she describes, going to My Account and then through Education.
