In our industry, product and systems and configuration knowledge is required of both ES Sales people and ES Technicians in order to provide the best value to the customer and protect them from shoddy installations that do not deliver services they seek.  Current DCJS approved training courses for sales and tech already have some overlap; in my 20+ years in the industry, I have observed that effective sales people need to understand product capacity and installation practices, and techs need to be cognizant of the sales perspective.  I recommend you combine the sales and technician in-service training course curriculums and only require one in-service training course completion during the registration renewal period, regardless of how many different categories a person is registered under.  This will streamline the compliance process for both DCJS and licensees, and reduce frustration and loss of productivity among our workforce.
