The CDL Mill will not only survive -- but thrive -- because carriers are more than happy to hire the CDL Mill product.  As a result, an incredible amount of responsibility is placed on the shoulders of untrained trainers to do the job that by all rights, the school should have done.

  Some carriers institute "Train the Trainer" courses in an effort to better inform trainers.  While this is commendable, it is not even close to enough.  A 1 to 2 day course cannot teach someone how to teach.  Most trainers know how to perform their jobs well and they assume that this is enough qualification.  When their trainee cannot shift or back, few trainers truly know how to walk the trainee through the procedure.  Just because you know how to do something does not mean that you know how to teach someone else how to do it.
