Toyota USA has a complete training schedule for it's dealer techs. Starts with basic PM training, mast overhaul, general products and engines, electrical systems and theory and so on. It covers their whole line of products with 3 levels of certification. To get to their gold level, you have to work for a Toyota dealer for a minimum of 5 years.
An excellent system.

Makes sense. lately I have seen a lot of OEM advertising that their dealers have x number of certified technicians. I am curious what constitutes a certified tech

There is a lot of pre training required before you can take a specific model class. I am certified an all models except 2. I probably have 200 hours of class time plus hands on. I have been doing this for a long time. Times are changing, Some of our new hires have little experience so we have developed basic classes. These people will require at least 40-80 hours of basics before they start on the certification path. This does not include the hands on training during their first 6 weeks.

some classes are 3 days, it depends on the model and level you are learning. The more advanced classes take a week.
I took the I3 class that covered all electric models that had that system in it, that was a week long class and the test took several hours, part of it was hands on and the rest was online.
The hands on part i think was our trainers way of verifying you knew what you learned.

To get trained on all models it would take quite a while ;o)
Generally the dealership determines which classes they want you to take depending on the trucks in your customer base. No need to take classes on trucks you don't work on (their thinking not mine).
If i had my way i'd take em all ;o)

Thanks for the feedback. So only 3 days certifies a technician as a "factory certified" tech? or is that just a model specific course?

I answered this question once. It depends on the OEM and the dealership you work for. Hyster/Yale has certifications for all model groups. You have to attend a 3 day class and then complete a online exam. There are multiple layers of certifications that require additional training modules to be completed. this is a lot like automotive certification.
