Certainly there would be an advantage to have a cross checking audit of training. But from my past experience the likelihood of this happening is minimal. In the mid 90's I was involved in dealer training, I & all lift truck ITA members were polled by a very proactive member of the lift truck industry to produce a "consistent" message & content for lift training videos that would be OSHA compliant. At this point in time new OSHA regs were being implemented and everyone needed to up date their training materials. One of the objectives was to reduce cost of production from about $60K (do it on your own) to $30K per video/CD master by setting up a consistent scene with one "video house" and each participant would have their lift truck brand videoed the same way in each scene with no "advertising" messages - just good operator safety instructions. Each company could add to there video/CD master a brand specific leader and trailer messages. The company I worked for was in favor of this approach as we built two brands and would need to produce 3 videos for at least 3 types of equipment (counterbalanced, narrow-aisle & walkie) for each brand. Great idea but there was not enough overall support by the other members to move this project forward (legalize and the "competitive spirit" got in the way) so the idea & project "died the death of a rag doll".
Heck, we have 50 different states and probably have 50 different ways to be "tested" for our drivers license. In the great state of Georgia you only need to be able to pass a parallel parking maneuver for the road test part of the examination (and the results show). In Illinois (and other states I'm certain) they "were" very strict in the late 60's you actually went on the road & the examiner deducted points for every minor infractions - like not using a turn signal when pulling away from a curb at the exam center and not having both hands on the steering wheel.) At that time, I had been driving for 10 years ( only had two tickets - one speeding 5 over and a citation for a my fault one minor accident - when I was younger) and I passed by only 6 points.
