Prep boundary
Direct answer
Why should a journeyman or master-plumber candidate read the state candidate bulletin before drilling questions is a TradeCert Prep study concept connected to Plumbing License Practice Test prep, not a copied official exam item. State plumbing boards and exam vendors can change eligibility, references, and test logistics. Practice should be checked against the current official bulletin. Always verify licensing, certification, and testing rules with the current official candidate bulletin, state manual, code book, or testing provider before relying on a detail for compliance.
