Introductory FRED Tutorial

Our in-person FRED Introductory Tutorial training class is indefinitely postponed due to the COVID-19 pandemic.  We are hopeful to resume our in-person classes at some future date.

We are currently offering an online version of our 3-day FRED Introductory Tutorial class online in a self-paced, on-demand format.  Although we cannot entirely replace the in-person training experience, we believe that the online tutorial format will still be a highly effective and convenient way for you to come up to speed quickly on FRED.

The online tutorial format is built around a hands-on learning experience and accompanied by nearly 20 hours of pre-recorded lecture and demonstration videos to help guide your FREDucation.   Of course, you will also have access to the course instructors  should you need additional assistance during the class.

  • $1,785.00 per student registration (non-refundable)
  • 30-day access to video content hosted on the Teachable platform
  • Downloadable PDF lecture notes and example files
  • Access to FRED technical support
  • Does not cover scripting (separate online tutorial coming soon)
