OK, it's been a while since I was instructing, but for what it's worth.....
ALL of my PPL students were exposed to some spinning - even if it was only a demo - just so they could see how fast things could go wrong. Some students wanted to go futher and I was happy to spin with them and let them do the recovery - some had one demo and never wanted to see a spin again....
I would NEVER suggest that ANY PPL student went off solo to practice spinning -
The same applies to PEF - I encouraged the students to think about the 'what ifs' - field selection, where they would go if it all went horribly quiet up front, what there action whould be, etc, etc but I wouldn't encourage them to practice without an instructor sat next to them.....
Unless things have changed a lot since I left instructing, I would keep to the same rules now....
