It occurred to me while reading through this thread that, much as I and some others have sung the praises of the USFS chainsaw training and certification program, it really puts emphasis the ability to perform skills to achieve certification. The cert. is based on a day of classroom presentation and discussion, followed by a day cutting in the field under the eye of the instructor. If the trainee fails to perform adequately on that day, they just don't get certified and don't get to cut on the job, rather than automatically getting additional training as a matter of course.
This is a far cry from the sort of mentoring of apprentices over an extended period of time that Stig offers, and is obviously an inferior system.
A few of us experienced FS instructors take it a lot farther than the basic S-212 program, taking the time to actually help cutters learn the ropes, but it's done on our own initiative...frequently responding to a special level of interest we see in a particular youngster. That was what was going on in the hazard tree fell in the Day in the Life thread. Too bad it's not more on the model of a true mentoring program.
Our tree climbing training and certification program is a little better, generally training is spread over 4 or 5 days, with lots of 1 on 1 time between instructor and student, but in the end it's just a week. To really produce a fully qualified, safe and efficient climber clearly takes longer. We help that process along by utilizing a trainee climber cert. level, requiring a specified amount of time working as climbing partner with a fully certified climber, with more experience. But that fully cert. climber doesn't have to be certified as an instructor, so it's a crap shoot as to how well they mentor.
We do better than average on training people, I guess...but there surely is room for improvement. It definitely would cost more to do it better, but I wish we did.
