Forty employees from 18 regional companies are attending a weeklong Refresh Tech class, an interactive review of selected topics designed for multidisciplined maintenance technicians and offered by Workforce Development & Continuing Education at Penn College. Divided into two sessions of 20 students each, the class was quickly filled due to $500-per-person scholarships from a Central PA Works grant administered by the nine-county Central Pennsylvania Workforce Development Corp. The course – taught by Thomas W. Fry, industrial technology specialist – began with electrical basics and discussed a number of other essential concepts before moving to a consideration of newer applications from a troubleshooter's perspective.
