I'm seriously contemplating returning to primary teaching. I passed my pre-reg year then quit. This was 15 years ago. I think I chronically lacked self-confidence back then. I see Edinburgh now does a return to teaching online course but I want to get some classroom time before I make the financial commitment of the course. How much time should I request to work-shadow in a particular school(s)? I want to see as much as I can/ask lots of questions without out-staying my welcome.
