Will your employer compensate you for being World Class? I work with 2 techs who are 100% in everything including hybrids and medium duty. They could just as easily become world class techs, but there is no more money to be made. Its just a title.
I stopped at the apprentice GM training, and only have 3 ASE's. The dealership didn't want to pay me any more, so no sense wasting my time.
