Iowa Electrical License Requirements — Exams, Reciprocity, and Contractor Setup

Iowa Electrical Licensing Is Statewide — No City-Level Licensing

Electrical work in Iowa is regulated at the state level by the DIAL Electrical Examining Board. This is one of the specialty trades where the state preempts local authority — no city can issue its own electrical contractor license or impose additional licensing requirements. Your state electrical credential is valid across all Iowa municipalities.

This is different from general contracting, where DIAL registration is administrative and cities handle permitting. For electrical work, the Electrical Examining Board controls who can perform the work, and local building departments simply verify your state credentials when issuing electrical permits.

License Classes

The Electrical Examining Board issues several license classes:

Apprentice Electrician — Entry-level registration for workers learning the trade under a licensed journeyman or master. No exam required.

Class A Journeyman Electrician — The working credential for performing electrical installations and maintenance. Requires passing the PSI exam and completing a registered apprenticeship or documenting equivalent field experience.

Class A Master Electrician — The supervisory credential. Required to serve as the electrical contractor's qualifying individual. More extensive exam and experience requirements.

Electrical Contractor License — The business credential. Requires a sponsoring Master Electrician.

Exam Process: PSI Testing

Unlike plumbing exams (which go through Kirkwood Community College), electrical exams are administered by PSI Exams at testing centers across Iowa and nationally.

Before scheduling an exam:

1. Submit a license application and testing sponsorship form to the Electrical Examining Board through iowaelectrical.gov
2. Receive an "authorization to test" letter from the board
3. Schedule your exam with PSI using the authorization

The authorization letter is valid for six months or two exam attempts — whichever comes first. If you fail both attempts, you must submit a new board application and start the authorization process over.

Class A Journeyman exam: Open-book, 3 hours, 80 questions based on the 2023 National Electrical Code (NEC). Passing score: 70%. PSI registration fee: $60–$87 depending on the exam category.

Class A Master exam: Open-book, 4 hours, 100 questions based on the 2023 NEC. Passing score: 70%.

The exams are open-book, meaning you can bring your copy of the NEC into the testing room. Familiarity with the code's organization is more important than memorization — knowing where to find answers quickly under time pressure is the practical skill the exam tests.

License Fees

Electrical licenses run on a three-year cycle with prorated fees based on entry date. A new Class A Journeyman license issued in July 2026 costs approximately $62.48, while a full-term fee is $75.00.

Master Electrician and Electrical Contractor licenses are $375.00 for the full three-year term.

Reciprocity With 13 States

Iowa's Electrical Examining Board maintains reciprocal licensing agreements with 13 states — one of the more generous reciprocity programs in the Midwest. Under Iowa Administrative Code 481 IAC 401.2(14), the reciprocity pathway requires:

• An active license in a participating state, earned by passing that state's written exam with a 70% or higher score
• The license must have been held continuously for at least one year
• No history of a failed Iowa electrical exam
• Completion of a Department of Labor-registered apprenticeship program, OR documentation of at least 16,000 hours of practical, licensed electrical experience via a notarized Affidavit of Experience

The reciprocity pathway typically waives the PSI exam requirement, which saves both time and money. Check with the Electrical Examining Board for the current list of participating states, as reciprocity agreements are reviewed periodically.

Insurance Requirements for Electrical Contractors

State-licensed electrical contractors must carry at least $1,000,000 in contractor liability insurance. This is double the minimum for PMSB-licensed plumbing contractors ($500,000) and significantly above what's required for general contractor registration (no state minimum).

This is separate from workers' compensation (required if you have employees) and separate from any municipal bond requirements.

Continuing Education

Electrical licensees must complete 18 contact hours of board-approved continuing education during each 3-year cycle. At least 6 of those hours must focus specifically on the National Electrical Code.

This is more than double the PMSB's 8-hour requirement for plumbing/mechanical licensees, reflecting the code-heavy nature of electrical work and the frequency of NEC updates.

How Electrical Licensing Connects to General Contractor Registration

If you run a construction business that performs electrical work alongside general contracting, you need both credentials: DIAL contractor registration for the business entity, and the Electrical Examining Board license for the electrical work.

The two registrations are separate applications with separate agencies, fees, and renewal cycles. Your DIAL registration renews annually; your electrical license renews every three years. Missing either one can prevent you from pulling permits — municipal building departments check both.
