i see.. yeh.. here you can't get liscensure with a MA... and you can get registered as a art therapist but since it's not truly really accepted, most places won't hire you with that alone unless it's a school or something with a program oriented toward art therapy. I love art therapy... i got a chance to take a few courses at my Uni's extension as they have a art therapy program and some of the classes were open to people not in the program.
Here, you can get liscensed as a therapist with a MFT, a MSW and some states a LRC which might be the same thing as a MFT. Other than that, you have to become a psychologist or you work under other people and can't have independent liscensure.... which i really think kinda sucks in some ways and not on other ways...
good fortune
