Journeyman & Apprentice Training Center

Located 22 miles southeast of Sacramento, the California OE3 JATC site consists of an 11-½-acre campus, with an additional 1,500 acres devoted to crane, heavy equipment, CDL and a maintenance area, where hands-on training is conducted. The facilities are used to upgrade and multiply the equipment skills of members of the country’s largest construction union in North America, Operating Engineers Local 3.

Instruction is on an ongoing basis during the six-week Probationary Orientation Period (POP) for new apprentices. After the probationary period, apprentices are required to successfully complete 80 hours of Supplemental-Related Training (SRT) for each step of the Apprenticeship Program, usually once a year.

The OE3 JATC also offers continuing education and training for journey-level operators. Rapidly changing technology in the construction industry creates a need for continuous training to stay relevant and marketable in your field. We provide that.

Your Career Begins Now!

Remember: The training is at no cost to you, and once you complete the initial eight-week training, starting wages with an annual cost-of-living increase are $25.87 an hour. Our jurisdiction is from the Kern County line to the Oregon border. All applicants must reside in our area to be considered for the program.
