Over the last two years, though, people have been talking about the service classes available through International Service Leadership (ISL). Contractors from around the country have mentioned how much they and their technicians have learned from the classes and how they've been able to apply that information directly to their jobs.
Most of the credit for ISL's successful service classes can be traced back to Duff Maynard, ISL's director of training in Brentwood, Tenn. Since 2001, he and his staff have revamped all the curricula for the classes. He is also in the process of creating new curricula for higher-level service classes, as well as classes for the support positions in a contracting firm.
