Just to clarify some misconceptions in here and to put some know-it-alls in their proper place....
When a TSO is newly hired, upon completion of the basic screener training course, that new TSO has to pass an x-ray imagery test. Upon completing 60 hours of on-the-job training, that TSO has to pass another x-ray imagery test but at a higher standard. From that point on, that TSO takes a quarterly x-ray imagery test that he/she must pass at an even higher standard. And on top of that comes an annual skills certification test that includes yet another x-ray imagery test but at the same standard as the quarterly test. If they fail to meet TSA standards during any one of these tests, the TSO is terminated.
When a TSO fails to detect a Red Team test bag, that TSO undergoes remedial training. At the end of remedial training, the TSO must pass an x-ray imagery test. And again, if that TSO fails to meet TSA standards, then that TSO is terminated.
For those of you who think that the TSOs who failed to catch those bombs only received a slap on the wrist, please do yourselves a favor and think again, cupcakes.
