How to get licensed
- 1
Meet the prerequisites
Be at least 18 years old, pass a criminal background check. Applicants must be at least 18 years old. The application requires disclosure of criminal history, with supporting court documents if applicable -- this is a self-disclosure requirement rather than a state-run fingerprint background check, but is recorded as true since criminal-history review is a stated part of the application. [1]

Complete approved training
Complete 6400 hours of training. Applicants generally qualify via at least 4 years in an apprenticeship program (commonly cited as 576 classroom hours plus 6,400 hours of supervised work, though the classroom-hour figure is not restated on the PLA's own licensing-information page), documented with a Plumbing Apprenticeship Certificate of Completion signed by the sponsor. Alternatively, an applicant holding a current out-of-state plumbing license can qualify via an Affidavit of Experience in the Plumbing Trade from an employer, without completing an Indiana-registered apprenticeship -- so approvedProgramRequired is false. hours=6400 reflects the supervised-work-hour component of the standard apprenticeship pathway.

Indiana Journeyman Plumber Examination
Pass the Indiana Journeyman Plumber Examination (fee: $75). Computer-based, open-book; 90 questions, 3 hours allowed. References: 2006 International Plumbing Code (Indiana edition) and the 2012 Indiana Amendments (675 IAC 16-1.4). Applicants must first be approved by the Indiana Plumbing Commission, then register and pay the $75 exam fee directly to Prov. Up to 7 attempts are allowed within a 2-year period, but the first attempt must occur within 1 year of approval or the applicant must reapply. [2]

Fees
| Fee | Amount |
|---|---|
| Application fee [1] | $30 |
| License fee [1] | None specified |
| Renewal fee [1] | $30 |
| Indiana Journeyman Plumber Examination [2] | $75 |
| Prov examination fee [1] | $75 |
| Late renewal (after 12/31, before 3/1) [1] | $15 |
| Late renewal (after 3/1) [1] | $100 |
The $30 application fee and the $75 Prov exam fee are the two fees paid to obtain the license; no separate license-issuance fee beyond these is listed on the PLA's licensing-information page, so license is left null rather than duplicating the application fee.
Renewal & continuing education
Renew every 2 years.
Journeyman Plumber licenses expire December 31 of every odd-numbered year (a 2-year cycle) and renew for $30. Indiana does not mandate continuing education for renewal, so ceHours is left null (not simply unpublished -- there is no requirement).
Reciprocity
Endorsement/reciprocity from another state is available.
An applicant holding a current out-of-state plumbing license can apply via the trade/experience route (out-of-state license documentation plus an Affidavit of Experience in the Plumbing Trade from an employer) instead of completing an Indiana-registered apprenticeship -- but must still pass the Indiana Journeyman Plumber exam administered by Prov; this is not a waiver of Indiana's own exam. No interstate compact covers plumbing.
