The mental health aspect isn't mentioned on the DOJ website.

Copy and paste of the relevant section:
"Out-of-state Licenses Recognized in Wisconsin
Licensees from any of the listed states will be recognized in Wisconsin as an out-of-state licensee per Sec. 175.60 (1)(g) Wis. Stats. This was determined based on the statutory requirement in s. 165.25 (12) that the listed state requires, or designates that the holder chose to submit, to a background search that is comparable to Wisconsin’s background check in s. 175.60 (1)(ac). Wisconsin’s background check includes only two components (1) A criminal history record search; (2) A search of the national instant criminal background check system (NICS). If another states background check meets the same requirements a Wisconsin resident must meet, the DOJ has recognized that state. The DOJ has tried to be as inclusive as possible and will periodically check and update the list if other states can be added. This list is current as of 10/18/11:
Arizona, Arkansas, California, Colorado, Connecticut, Georgia, Hawaii, Idaho, Iowa, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Nebraska, New York, North Carolina, North Dakota, Pennsylvania, Tennessee, Texas, Utah, Washington, Wyoming, Puerto Rico, U.S. Virgin Islands"
And I know the training 'shouldn't' have anything to do with it, but since they decided we needed a minimum of 4 hours, I thought maybe the DOJ decided others we would recognize would as well.
That being said, I wonder if MO just didn't respond by the date listed (10/18/11)?
And I guess it's just semantics, but it would be reciprocity since Missouri will recognize ours as of Nov1. Not an official agreement, but the same result. They recognize all other states' permits by statute. source:

ETA: According to Missouri's website we do honor their permit!?!
