If you want to start a plumbing career in Indiana, the first step is proper training. In this state, plumbers need both classroom instruction and on-the-job experience before getting licensed. Choosing the right school can speed up your path to earning that license.

How Plumbing Licensing Works in Indiana

In Indiana, plumbing is a licensed trade. That means you can't legally work as a plumber without meeting the state's requirements.

According to the Indiana Professional Licensing Agency, plumbers must first complete an approved apprenticeship before applying for a journeyman or plumbing contractor license.

Here are the basic steps:

  1. Apply for an apprenticeship with a union, trade school, or employer that offers a state-approved program.
  2. Complete at least four years of combined classroom and on-the-job training.
  3. Pass the state exam for journeyman or plumbing contractor, depending on your career goal.
  4. Maintain your license by following renewal and continuing education rules.
