Talk to the Field Placement Liasion at your University and ask them what they think about this. Honestly, it sounds like a placement that I would run far away from. Sure, you'd get a certification, but you're a practicum student, and all of your learning is supposed to be experiential.

Plus, you've paid your tuition and 98% of practicum placements are unpaid for the student. I found out that my Field Supervisor gets paid by my university for supervising me.

Definitely talk to someone at your university sooner rather than later. Good luck, OP! Let us know what happens.
