Iowa contractor exam prep
Iowa contractors are licensed by the Iowa Electrical Examining Board (DIAL). Use the classification list below. Some states fold business questions into the trade exam. We do not sell a standalone Law & Business paper for Iowa.
Confirm question count, time, open-book rules, and passing score on the live board bulletin before you sit. We do not publish a single Q-count for every classification on this page, and we do not guarantee a passing result.

Who licenses contractors in Iowa
These are the Iowa classifications we build exam prep for, each licensed by its responsible board:
| Trade area | Licensing authority | Exam basis |
|---|---|---|
| Electrical | Iowa Electrical Examining Board | National Electrical Code (NEC) |
| Plumbing | Iowa Plumbing and Mechanical Systems Board | Adopted plumbing & fuel-gas codes |
| HVAC / Mechanical | Iowa Plumbing and Mechanical Systems Board | Mechanical & fuel-gas codes, EPA 608 |
Always confirm the current code edition, experience requirements, fees, and passing score with the board and testing vendor before you schedule. Contractor Pathway is an independent exam-prep provider and is not affiliated with any Iowa board or testing vendor.
How to get licensed in Iowa
Iowa licenses the plumbing, HVAC, refrigeration, hydronic and sheet metal trades through the Plumbing & Mechanical Systems Board, and the electrical trades through the Electrical Examining Board — both administered by the Department of Inspections, Appeals & Licensing (DIAL).
- Journeyperson: 36 months of registered apprenticeship. Exam candidates must have completed a minimum of 36 months in a U.S. Department of Labor registered apprenticeship programme, or hold at least four years of experience obtained prior to 1 January 2010.
- Master: two years as a licensed journeyperson. Master exam candidates must either have been previously licensed as a journeyperson with two years of journeyperson work experience in the applicable discipline, or have held a master licence in that discipline in another state or local jurisdiction.
- Sit the exam through the approved provider. Iowa charges $35 per trade examination, delivered through Kirkwood Community College as the Board’s approved examination provider.
- Renew on a three-year cycle. Plumbing & Mechanical Systems Board licences are issued for a three-year licensing period. Renewal typically requires 8 CEU hours, of which at least half must be in person — up to half may be completed online.
- Mind the scope of your licence. Iowa licenses by discipline — plumbing, HVAC-refrigeration, hydronic and sheet metal are separate credentials, alongside specialty, contractor and medical gas piping certifications. Confirm which discipline your work falls under before you apply.
