A typical onsite agenda for a Fundamentals of Geometric Dimensioning & Tolerancing course is shown below.

GD&T Fundamentals Typical 3-Day Onsite Course Outline

Note: Some training companies have spread this same content out into two, 2-day courses, which they typically call “Fundamentals” and “Advanced” GD&T, saving “more difficult to teach” topics (like composite vs. two single-segments) for the “Advanced” class. We’ve responded to the pressure of having increasingly greater content to teach by coming up with better ways to teach more content in a shorter period of time, allowing us to cover material in 3 days that many other companies require 4 days to cover.  Also, we are happy to customize the training to meet other time-lines or to include related content, including a version that emphasizes applications to fixtures and gaging described in ASME Y14.43-2011 Dimensioning & Tolerancing Principles for Gages and Fixtures.
