The Fundamentals of GD&T class.  This class is 20 hours.  Historically it was done over 3 days, but most companies now prefer to do 5 half days.

The material used in the Fundamentals class is purchased material.  I have taught this class with material from several different sources and found this to be the best Fundamentals material.  

The class consists of a combination of lecture and exercises.  Exercises are often where the most learning takes place.  Normally the exercises are done together as a class with students volunteering answers and asking questions. Dimensional Consulting has developed special Powerpoints to use when going through the exercises.  These Powerpoints help clarify questions, explain why the answers are what they are, or point out exactly where in the book a given answer can be found.  Feedback from students has been that they find the use of these Powerpoints during the exercises to be quite helpful to the learning process.
