Apprenticeship & Internship Programs
Opening Doors
The apprentice-to-employee pipeline is real at Metropolitan. Apprentices who complete Metropolitan’s four-and-a-half-year program (which includes a six-month probation period) earn a journey level certificate, 36 hours of college credit applicable toward an associate degree, and an offer of full-time employment at Metropolitan. The program, geared for mechanical and electrical operations technicians, uses a combination of on-the-job experiences, classroom instruction and home study. It is certified by the state of California and overseen by a joint group of Metropolitan managers and labor representatives. It’s considered to be a model apprenticeship program. The truth behind that statement is found in the stories of dozens of employees throughout the organization who began in the apprenticeship program and built on their careers at Metropolitan.

The Apprenticeship Program
A six-month pre-apprentice training period must be completed to participate in the four-year Apprenticeship Program. Participants perform trade and non-trade duties in general maintenance and general labor. You might assist in operations and maintenance tasks at pumping plants, treatment plants and in the distribution system. You also may learn and use basic tools and techniques, or operate a motor vehicle that includes a pickup truck, forklift or other light equipment, as required.
Training as an Apprentice
The four-year program is eight periods, each with a minimum of 910 hours, or about six months, of instruction and on-the-job training. Field training is with a journey-level employee who is a qualified apprenticeship instructor. For every hour of classroom study there are about two hours of home study completed on the apprentices’ own time, outside of work hours. Classroom training typically takes place at the Apprenticeship Training Center at Diamond Valley Lake, near the city of Hemet.
Apprentices are eligible for advancement with a pay increase at the end of each period providing they maintain a passing grade of 70 percent or higher on exams and meet the standards of performance in their field work.
