Dean’s advice
Don’t give up
California had about 47,660 plumbers, pipefitters and steamfitters in May 2025. Many get there through an apprenticeship, and for a lot of people the hardest part is simply getting in.
The biggest mistake new apprentices make
From the dean’s desk
Giving up too soon. It can be difficult to find an apprenticeship sometimes, but don’t give up. Keep working at it, because once you get in, it’s worth it.
— Lester Burkes, Dean of Trades, Transportation & Apprenticeship
Apprenticeship programs often open applications only at certain times and may have more applicants than spots. People who keep applying, keep improving their application and stay in touch with programs are the ones who get in.
