The Indiana Professional Licensing Agency oversees the Indiana Plumbing Commission, which issues and renews the statewide plumbing licenses. It is illegal to perform any plumbing services in Indiana without a state-issued license. To join this workforce legally, you must begin by registering as an apprentice. After four years as an apprenticeship working under a licensed plumber, one can apply through the approved program to get the journeyman license. We create these self-practice test questions module referencing the concepts and principles currently valid in the written exam. Each question comes with an answer and a short explanation which aids you in seeking further study information. For purpose of exam readiness drilling, this product includes questions that have varying numbers of choices. Some have 2 while some have 5 or 6.
