What Is A IA-ME?

What the IA-ME Actually Is

The IA-ME - the Iowa Master Electrician License Exam - is the credentialing test that Class A journeyman electricians in Iowa must pass to become licensed Class A Master Electricians. This is distinct from Iowa's separate Residential Master pathway; the IA-ME specifically targets the Class A Master examination track, which covers commercial, industrial, and general electrical work rather than residential-only scope.

If you're asking "what is a IA-ME," the short answer is: it's a computer-based, open-book, multiple-choice licensing exam administered on behalf of the state of Iowa. Passing it is the gateway to supervising electrical work, pulling permits as a master, and running your own contracting operation under Iowa law. For a broader breakdown of terminology and related naming conventions, see IA-ME Meaning and What Does IA-ME Stand For?

Who Runs the Exam and Who Administers It

Licensing authority for the IA-ME rests with the Iowa Electrical Examining Board, which sits within the Department of Inspections, Appeals, and Licensing (DIAL). The Board sets eligibility rules, approves sponsorship, and issues the actual Class A Master license once a candidate passes. The exam itself, however, is delivered through PSI Services LLC, the third-party testing vendor that hosts the official exam bulletin, schedules test sessions, and scores results.

This two-party structure matters for candidates: DIAL/the Board controls who is allowed to test (sponsorship and authorization), while PSI controls how and where you actually sit for the exam. Understanding this split helps you avoid confusion when tracking down forms, deadlines, or rescheduling policies.

Eligibility to Sit for the Exam

Standard eligibility for the IA-ME requires one year of Board-acceptable experience working as a licensed Class A or Class B journeyman electrician. There's also an alternate route: an active Class B master electrician may use an examination-upgrade path to sit for the Class A Master exam without restarting the journeyman clock.

One detail candidates frequently overlook: the approved master examination must have been passed within 24 months before the license application is submitted. Passing the test isn't the finish line - if you wait too long to file your application, your passing score can expire. Before you can even schedule with PSI, you need Board sponsorship and authorization, and that authorization is only valid for two attempts or six months, whichever comes first.

Exam Format, Timing, and Scoring

The IA-ME is a computer-based, multiple-choice, open-book exam. It consists of 100 scored questions plus 10 unscored (pretest) questions, for 110 total items. Candidates get 240 minutes for the scored portion and an additional 30 minutes allotted for the unscored items, totaling 270 minutes of seat time.

Passing requires answering 70% of the scored items correctly. The unscored questions don't count toward your result but are indistinguishable from scored ones during the test, so every question deserves full attention. For the exact math behind the passing threshold and how it's calculated, read IA-ME Passing Score 2026: Exactly What You Need to Pass.

The single reference source for the entire exam is the NEC 2023 edition - DIAL confirms this code cycle has been used for testing since January 1, 2024. Every code reference question on the IA-ME draws from this edition, so studying an outdated NEC cycle is a common and costly mistake.

The 8 Exam Domains

The IA-ME content outline is organized into eight domains, each carrying a specific weight of the scored questions. Understanding this distribution is the single most important step in building an efficient study plan - it tells you exactly where to spend your limited prep time.

Together, Wiring and Protection, Wiring Methods and Materials, and Equipment for General Use make up 65% of all scored content - nearly two-thirds of the exam. The remaining five domains fill out the rest:

Fees, Sponsorship, and Scheduling

As of the PSI-hosted bulletin updated September 19, 2025, the exam fee is $87 per attempt. This is separate from the license itself: the full three-year Class A master license costs $375, with initial fees prorated depending on the month you're issued the license. The current licensing cycle runs 2026-2028.

Before scheduling with PSI, you must first obtain Board sponsorship and authorization - this is not optional and cannot be skipped by simply paying the PSI fee. Once authorized, you can book your test date, but you must cancel or reschedule at least two days before your scheduled testing appointment or risk forfeiting your attempt.

Approved Materials and Calculator Rules

The IA-ME is open-book, but the rules on what counts as "the book" are strict. Only the 2023 NEC or the 2023 NEC Handbook are approved references. You're allowed to bring a copy with advance highlighting, underlining, and permanent indexing already in place.

What's prohibited is just as important: handwritten notes, removable tabs, extra loose papers, and Ugly's Electrical References are all banned from the testing room. If you've built a study habit around Ugly's, you'll need to shift that reliance to NEC-based lookups well before test day.

For calculations, candidates may use the on-screen calculator provided by the testing software or bring an approved nonprogrammable, nonprinting calculator. Bringing an unapproved calculator model is a common and avoidable disqualification risk.

Retake Rules and Continuing Education

Iowa's retake policy escalates in stages. After two failed attempts, candidates must wait six months and complete 12 approved continuing-education hours before testing again. That same six-month wait and 12-hour education requirement applies again after a fourth failure. After six total failures, further attempts require formal Board approval following a petition and yet another six-month wait.

This structure rewards candidates who treat each attempt seriously rather than treating the exam as low-stakes repeat practice. For data on how candidates perform overall, see IA-ME Pass Rate 2026: What the Data Shows, and for an honest assessment of exam difficulty, see How Hard Is the IA-ME Exam? Complete Difficulty Guide 2026.

Once licensed, renewal requires 18 approved continuing-education hours across a full three-year term, including at least six NEC-specific hours as defined under the Board's continuing-education guidance. Shorter initial license terms (for those issued mid-cycle) require six hours for each year or partial year licensed.

Who Takes the IA-ME and Why

Candidates pursuing the IA-ME are typically experienced Class A or Class B journeyman electricians who want to move into supervisory or ownership roles - pulling permits as the master of record, running crews, or launching an independent contracting business in Iowa. Active Class B masters upgrading to Class A status also sit for this exam via the upgrade route described earlier.

Employers value the Class A Master credential because it signals both code fluency and the legal authority to take responsibility for electrical work at a broader commercial and industrial scope than a journeyman license allows.

Preparing Efficiently for the IA-ME

Because Wiring and Protection, Wiring Methods and Materials, and Equipment for General Use together account for 65% of scored content, your prep calendar should weight time accordingly rather than spreading effort evenly across all eight domains.
