I have taken my courses at the following:
Compliance Education Institute, LLC
https://compliance-edu.com
The trainer is Mick Kless and he is amazing.
There are several levels of certifications for Vendor Management. I have completed levels 1 and 2 and am on the last chapter of level 3. It starts out at a beginner stage, then takes a deeper dive with each certification.
He also has specialized courses for certain things or can customize to your needs.
The certification courses are on-line for $499.00 and you work at your own pace. With the course, you get access to documents and he is available for you to answer any questions you have. I rely on him regularly. Especially, when I have a new type of vendor that I'm not sure how to vet.
Check out his website or email him.
I highly recommend him.
Sincerely,
Cheryl Turner, CRVPM II
Vendor Manager
