Carl Zeiss IMT offers a training course called "GD&T-Applied to Coordinate Metrology"
I have not yet take the course myself, but plan to in the near future. They are only offering 4 classes that I know of at this time and setting is limited to 25 people per session. For registration contact Kim Adkins at kadkins@zeiss.com or call (248) 486-7620, they may be able to give you more info.
Good Luck!
