PSE dealer school is a fairly in-depth "training course" on bow tuning, set-up, & maintenance. From what I understand it's a pretty good course. For many dealers, like Len or Pinwheel it's probably not something they'll learn anything from, but for many, many dealers it's probably sorely needed.

At the end of the course dealers get to build thier own bow to take home with them (in essence a custom model can be made if wanted).
