I’ve never heard of any formal training in CP being given (mum, dad, bro & sis all teachers, so you’d think I would’ve heard something over the years), but hark to the following…
At one time my girlfriend was the daughter of our school’s secretary, who hosted frequent Friday night parties, attended by many of my teachers. The information leaked back to me was, of course, total Goldust (who were the drunks, who was due in court the next week, etc) but among such valuable intelligence came news of the conversion from anti to pro-CP of Anya, our Russian teacher, whose pacifist principles had been destroyed by a year of trying to educate mouthy English teenage boys.
