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.
