California OE3 JATC

Do you want a career that takes you places? It all starts at one of the country’s most prestigious training centers, the California Operating Engineers Journeymen and Apprentice Training Center (OE3 JATC), where apprentices train for free!


Apprenticeship Application

Now accepting applications until June 30th. Applications must be emailed or postmarked no later than June 30th and include the six-digit code from our current orientation video.

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 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.

Instructors at OE3 JATC are required to attend new and advanced instructor training through the International Union of Operating Engineers (IUOE) to ensure the continued quality of the program and the high standards established for the staff.

Instruction is on an ongoing basis at OE3 JATC during the eight-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.

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 learn new techniques and methods and improve existing skills.

Operating Engineers are often First Responders to provide fire breaks and then called upon to provide cleanup work in the aftermath. If you’re interested in helping communities rebuild and recover, the union is offering Hazmat Refresher courses, starting this month. Click on the schedule for more information and sign-up!
