In Minnesota, backflow preventer assembly testers are regulated by the Department of Labor and Industry, and the certification is a designation that is added to a plumbing license. Their website says that any program accredited as an ASSE 5110 course is acceptable.

No we don't. This website is mostly set up just to exist if we end up doing courses in the state at a later date.
All of our courses utilize the University of Southern California, Foundation for Cross Connection Control and Hydraulic Research ( USC-FCCHR ) 10th Edition testing procedures and diagnostics, using derivative materials and auxiliary tests if applicable by the local authorities.
On our YouTube Channel, we created a series of videos explaining the testing procedures:
