No, they never did. I would've never allowed it. I wanted my process to be completely private, never wanted my personal private life to become a didactic material for students.

That said, when I was a student, we got to watch through the "two way mirror" real therapy sessions with real clients conducted by our instructors (the clients were informed and signed a consent form, of course). They got a good number of free sessions (I think, it was 20) in exchange to being watched by the students.
