#### Description

Students must first secure placement in the Alameda-Contra Costa Transit District's Heavy Duty Coach Mechanic Apprenticeship Program before enrolling in APAC 9471 through 9478. This program lasts four years and prepares individuals to apply technical knowledge and skills to repair, service, and maintain diesel-based coach and transit buses. Combining strong classroom theory with hands-on work that employs the latest tools and equipment in a state-of-the-art facility, the program teaches the essential skills that will allow graduates to troubleshoot and repair mechanical, electrical, and electronic systems in diesel engines and coach buses. Students will learn to use computers to diagnose equipment and research information. They will be trained to operate software, shop machinery, heavy-duty equipment, and use precision tools. Heavy Duty Coach Mechanic Apprentices must complete 198 hours of related supplemental instruction (RSI) per calendar year (or 99 per semester) hours per year at the AC Transit training center.
