VGI was an early developer of training for the Section 609 Automotive EPA Exam.  The same is true for the Section 608 Stationary Equipment EPA Exam.  In 1993, VGI was one of 12 testing organizations approved by EPA deemed qualified to offer the national Section 608 exam required for Stationary Equipment technicians.  It was the only private company so selected.  The VGI Training and Testing Module for EPA Section 608 has been used by more than 500 training organizations.  A majority of these training entities continue to use the module.

VGI, in concert with all HVAC systems manufacturers, was the original developer of the North American Technician Excellence (NATE) outlines and national testing regimen.
