Dear Rachel,
Thanks for your question! I inquired with Dr. Bill Berkowitz, a core team member at the Community Tool Box, and prior administrator of the Community Psychology program at University of Massachusetts Lowell.
He shared that the field of community psychology doesn't designate clinics as "Community Psychology clinics" so there are not guidelines on this particular question.cHowever, the Society for Community Research and Action (SCRA) the professional community psychology association, has a Council on Education. They can likely give guidance on selecting practicum sites. You might write to them at CEP@scra27.org.
Hope this is helpful and good luck!
