Well great segue..
50 yo... Got certified on the snowboard two years back and just went through the level II ski test. Didn't pass. Another "old fart" lady went with me (I'll be gracious on the age thing).
She didn't pass either. We come from the same ski area. We have been teaching for a long time.
After video taping myself, confering with her, watching the standards video, and talking with some guys who went to LIII we have decided that the examiners is looking for a specific body profile. You can decide for yourself if that translates to anything meaningful. My imprssion is that these guys beat around skier videos so that they get a picture in their head of the perfect level x. Problem is that it is big picture. The comments made by the examiners following the test were vague. Once again, this suggest again that it is a big picture thing. Our technical director also seemed just as confused as we were.
: So we are going to try again armed with our own support system and some educated guesses. FYI ... based on our exam feedback, folks on the PSIA alpine video don't seem match the standard either. Lots of "too much knee flex, butt behind the heels etc. So get the latest "standards" video from the ski school director. We will let you know how it turns out. The exam is long so conditioning is critical. If you are teaching each weekend it shouldn't be an issue.
Side effects of this effort were too bad. Several other guys who have been teaching forever and contemplating the test decided to skip the upgrade because they don't want the BS. At a certain point there is that BS vs Desire curve to consider. I think anyone can do it. What the hell else are you going to do at your age?
