Union or open shop?
Union
Run by a joint committee run by the United Association (UA) local and union contractors. You apply to the committee, take an aptitude test and an interview, and wait on a ranked list. The committee sends you to its contractors.
Pay is a set share of the union journey-level rate and steps up on a schedule. Classes are nights or week-long blocks, usually paid for by the program.
Open shop
Run by PHCC, ABC or a single plumbing contractor. You usually get hired by a member contractor first, and the contractor enrolls you.
Your employer sets the pay and the raises. Classes are nights or weekends, and some programs charge tuition.
What do programs ask for?
Age
Usually 18. Some programs take applications at 17.
High school diploma or GED
Most programs ask for one. Bring a transcript.
Aptitude test or interview
Union programs give an aptitude test (math and reading) and an interview, then rank applicants. Open-shop programs usually start with a job offer.
Driver's license and drug screen
Many programs ask for both, since apprentices drive between job sites.

Can't get in yet?
Pre-apprenticeship
Short programs, often free, that teach the basics and help with the application. Ask the programs above which ones they take graduates from.
Start on a crew
Licensed contractors hire helpers with no experience. Keep a log of your hours and employers; many programs and license boards count them. If you'd rather learn the basics first, 3 schools in Missouri have plumber programs.
