Iowa Master Electrician License: Requirements, Fees, and Scope

Iowa’s master electrician license requirements are shorter on time than most states and heavier on the exam. For a Class A master electrician license, you need one year of experience as a licensed Class A or Class B journeyman electrician, a passing score of 70 or higher on a supervised written exam covering the National Electrical Code and electrical theory, and a $375 fee for a three-year license issued by the Iowa Electrical Examining Board.¹²³

Who Qualifies

The base requirement is one year of experience as a licensed Class A or Class B journeyman electrician. That experience has to be “acceptable to the board,” meaning the Iowa Electrical Examining Board reviews what you submit and decides whether it counts.¹

Your exam score matters on its own timeline. A passing score stays valid for 24 months from the date you submit a new application. Wait too long between passing the exam and applying, and you may have to sit for it again.²

Two alternative paths exist. Current Class B master electricians can move up by passing the Class A exam. Electricians licensed by an Iowa city before January 1, 2008 under a supervised written examination, and who remain active in the electrical contracting industry, may qualify for a statewide Class A license based on that prior credential.¹

No college degree is required. Reaching journeyman status, though, involves completing a registered apprenticeship through the U.S. Department of Labor’s Bureau of Apprenticeship and Training for the Class A journeyman license. That apprenticeship provides the practical and classroom training the master exam draws on.

The Exam

The Class A exam tests the most recent edition of the National Electrical Code adopted by the board, along with electrical theory. The board sets the content and administers it on a schedule it determines. You need a score of 70 or higher to pass.¹²

Topics typically span wiring and protection, wiring methods and materials, equipment for general use, special occupancies and equipment, special conditions, and communication systems. The test has 100 questions and a four-hour time limit, which works out to about two and a half minutes per question. That is tight if you aren’t already fluent in NEC article structure.

The most useful preparation is time spent inside the code book itself. The exam rewards people who can locate answers quickly under time pressure, not people who have memorized isolated facts. Confirm which NEC edition Iowa currently has in effect before you start studying, because the board bases the exam on the most recent edition it has adopted.

How to Apply

Applications go through the Iowa Department of Inspections, Appeals, and Licensing (DIAL), which houses the Electrical Examining Board. Submit the board’s prescribed application form with the applicable fee. Payment is by check, money order, or warrant made payable to the Iowa Department of Inspections, Appeals, and Licensing.⁴ You can start the process online through the DIAL website; the department then emails you either to request payment or to ask for more information.⁵

If the board’s executive secretary sees something that needs closer review — questions about your education or experience, for instance — the application can be referred to a board committee, and processing takes longer. The board can also reject an application outright if you would be subject to disciplinary action under Iowa Code section 103.35.¹

Fees

The Class A master electrician license costs $375 for a three-year term. If the license is issued for less than the full three years, the fee is prorated by the number of months remaining.³

Other fees to know:

Replacement license if lost or damaged: $15.
Late renewal: 10% per month for the first three months after expiration.
Petition for eligibility determination, if you want the board to evaluate your qualifications before applying: $25.
Inactive master electrician license: $75 per three-year term.

First-time applicants whose household income does not exceed 200% of the federal poverty guidelines can request a fee waiver.³

Class A vs. Class B Scope

A Class A master electrician license authorizes you to plan, lay out, and supervise the installation of electrical wiring, apparatus, and equipment for light, heat, and power anywhere in Iowa. No political subdivision can restrict your scope of work.

A Class B master electrician license is more limited. Cities and political subdivisions that have established their own licensing standards can prohibit Class B holders from working in their jurisdictions. If you hold a Class B license and want that restriction removed, the route is to pass the Class A examination.¹

Renewal and Continuing Education

The Class A license expires every three years. Renewal requires 18 hours of board-approved continuing education completed before the renewal date. At least 6 of those hours must cover the electrical code; the remaining 12 hours are in related electrical topics.

Miss the renewal deadline and the late fee adds 10% per month for the first three months. Go beyond that window and you risk losing the license entirely and having to reapply. The NEC updates on a three-year cycle, and each edition introduces changes that affect how the work is done, so the continuing education requirement is enforced strictly.

If you want to hold the credential without actively working, the inactive master electrician license runs $75 per three-year term.³

What the Master License Doesn’t Cover: Contracting

Holding a Class A master electrician license is not the same as being licensed to operate as an electrical contractor. If you plan to contract on your own, Iowa requires you to carry public liability insurance and a surety bond. The statute authorizes the board to revoke, suspend, or refuse to renew the license of any electrical contractor who fails to keep both in force.⁶

Coverage and bond amounts are set by board rule rather than fixed in the statute, so check the current administrative rules or contact the board directly before applying for a contractor license. You can hold a Class A master electrician license and work under someone else’s contractor license without carrying your own insurance and bond. Once you operate independently, both become mandatory.

Reciprocity With Other States

Iowa has reciprocal licensing agreements with several states, including Alaska, Arkansas, Colorado, Minnesota, Montana, and Nebraska. If you hold a current license in one of those states, you may be able to obtain an Iowa license without retaking the exam. Specifics vary by agreement, so contact the board to confirm what documentation is required and whether any additional requirements apply. The arrangement works in both directions, which matters if you hold an Iowa license and work near the Minnesota, Nebraska, or South Dakota borders.

Penalties for Unlicensed Work and Violations

Working as an electrician in Iowa without a license carries a civil penalty of up to $1,000 per offense, and each day of a continued violation counts as a separate offense. Offenses arising from the same set of facts are treated as a single offense, so a week of unlicensed work on one project doesn’t automatically become seven separate penalties.⁷

The same civil penalty applies if you use the title “Class A master electrician” without holding the license, advertise services implying you’re licensed when you’re not, or help someone else work without a license.

For licensed electricians, the board can suspend, revoke, or refuse to renew a license for failing to pay required fees; violating the NEC as adopted by the board; violating local inspection ordinances in any political subdivision; or, for contractor licensees, failing to maintain insurance and bonding. These actions are taken by a simple majority vote of the full board.⁶

Presenting someone else’s license as your own, submitting forged documents to the board, or using a revoked license constitutes a fraudulent practice under Iowa Code Chapter 714.⁷
