I did them both at ITO in the early 90s when I was in the SO there. There was nothing handwritten in the study materials then. That LOC ended up creating problems for SO management because it basically gave the student pretty much free choice over his "hat in life", as far as I recall. So if someone posted as Toilet Cleaning I/C for the previous three years suddenly discovered he had always wanted to be a rock singer, the course checksheet went in the direction of him working out how to change his life and achieve that. Obviously this didn't go down too well with those trying to keep the show on the road. Some people were accommodated. Later, the materials were, er, "clarified" to remove this opportunity. I didn't see the revised materials, just vaguely heard about it. I was very happy to be a course sup, after some of the shitty posts I had held, so it was never a problem for me.
On KTL, the CT commands booklets were never given to someone buying the materials, although all the other books/booklets were. They were handed out by the sup and returned at the end of the session. The only confidential KTL items I know of were those on the KTL Delivery Course (which I did). I'm not sure if the confidential statements of the CT EPs were on that course or not--they certainly wouldn't be in the KTL materials given to students, just the sups. When I did KTL, the first CT process, a de-PTSing one, was mandatory for all. If you didn't need de-PTSing, it would have been a wrong step. (We won't look at the fact that pretty much everyone would be PTS to the :shark: but wouldn't be allowed to address that if they even thought of it).
