For out-of-state licenses to count for the P-1, the originating state's license must have required 720 classroom hours and 12,000 hours of on-the-job training.

Union and Non-Union Pathway
Connecticut plumbing apprenticeships run through UA-affiliated Plumbers and Pipefitters Local 676 (southern Connecticut) and Local 777 (statewide), and non-union programs registered with PHCC of Connecticut. CTECS trade high schools run adult plumbing programs statewide. Presented neutrally; verify current intake with each program.
P-1 Upgrade
To upgrade from P-2 to P-1, a Connecticut plumber must hold the P-2 for at least 2 years (or have at least 6 years of equivalent experience and training) and pass the P-1 exam. The P-1 is the credential required to contract for plumbing work and pull permits.
