We recommend prior to using this section that you search your specialty if listed.

This list of online providers offer CEU and CME credits approved by the Accreditation Council for Continuing Medical Education (ACCME) as well as many other accrediting bodies, such as the American Medical Association (AMA) and others.

Before beginning any course of study and testing, please be sure to verify the accrediting agency. Most impotantly, please verify the acceptance of the creditials by your state’s licensing board. In addition, ensure that the date of the CEU and CME is current and not expired.

Please be mindful that we are a portal to hundreds of sites found on the internet. Some sites are simple to use while others are a little more tricky to navigate. While we have tried to make our site as easy as possible to use, we can not guarantee the success of navigating on individual sites.

We will be updating this list periodically as we find more sites offering free credits.

All disciplines are well represented and usually can be found on some of the larger sites.


AARC Web Cast 1 CEU each, many to choose from RCP

There are a couple of things to consider before we classify these as free CEU’s. First, in order to get free CEU’s directly from AARC education you have to be a member which is not free to join. Secondly, these webcasts are only good for free CEU’s to AARC members for viewing the LIVE feed. “Live” is the key word as it means you have to be present during the scheduled showing. Once the show is no longer live, any replays of their archived broadcasts is going to cost $15.00.
