Here though is my issue with Tripoli Certification.
L1 is easy - no problem
L2 requires a test that is long and only shows how someone can memorize stuff. Kind of like many standardized tests that you can take over and over.
The Tripoli test (And maybe the NAR Test, not familiar with that one...) requires a 90% to pass. This is too high. You only need a 70% to pass the FAA exam to fly an airplane, with people in it. You only need 70% (In PA) to pass the drivers exam, again so you can transport people. You only need a 67% In PA, NY, NJ, and MD and I am sure others to pass the BAR exam and be able to represent people in court as an attorney... That is a D-minus grade...
Perhaps a more logical thing would be for a designated person be directly involved with observing a modeler prep his L2 rocket and show them what they are doing right or wrong. I.E. Help people, make them succeed, rather than look to bat someone down when they fail. A much more thorough safety check for the L2 certification flight.
L3 is ok, but I think that is where a test should be, if any.
