What You Are Actually Studying For
The Iowa Journeyman Electrician License Exam is the written, computer-based test that candidates take through PSI Services LLC as part of Class A journeyman licensure under the Iowa Electrical Examining Board. Current licensing administration sits with the Iowa Department of Inspections, Appeals, & Licensing (DIAL). If you are new to the credential itself, the overview at What Is IA-JE? covers the basics, and this guide focuses on the practical question: how do you pass it on the first attempt?
The short answer is that this is an open-book code exam, so passing is less about memorizing the National Electrical Code and more about navigating it quickly and applying it accurately under time pressure. Candidates who fail usually know the material in a general sense but cannot locate the governing rule fast enough, or they misread which article controls a given installation. Everything in this guide is built around fixing those two problems.
The 88-Item, 210-Minute Format
The exam is multiple-choice and delivered on a computer. What catches people off guard is that the test is longer than the number you are scored on. You will see 80 scored questions with 180 minutes allotted, plus eight unscored questions with 30 additional minutes, for a total of 88 questions and 210 minutes. You will not know which items are unscored, so treat every question as if it counts.
| Element | Detail |
|---|---|
| Delivery | Computer-based, multiple-choice, administered by PSI |
| Scored questions | 80 (180 minutes) |
| Unscored questions | 8 (30 additional minutes) |
| Total on screen | 88 questions, 210 minutes |
| Passing score | 70% on scored items |
| Exam fee | $87 |
| Permitted reference | 2023 NEC or 2023 NEC Handbook |
| Calculator | On-screen or qualifying nonprogrammable |
A 70% cut score on 80 scored items means you can miss a limited number of questions, but a passing score is a threshold, not a prediction of how many people clear it. For a deeper look at the scoring rule, see IA-JE Passing Score 2026: Exactly What You Need to Pass. Official cohort pass-rate figures were not verified for this article, so rather than quote a number, read IA-JE Pass Rate 2026: What the Data Shows for what can and cannot be said responsibly.
Get Sponsored Before You Study Hard
You cannot simply register and show up. Iowa requires Board sponsorship before you test, and that approval lasts for two attempts or six months. Studying for a window that expires before you sit is a real and avoidable mistake, so sort out your paperwork first and then time your preparation to the approval window. Current forms and administration are on the DIAL electrical licensing pages. Your full eligibility picture is covered in IA-JE Requirements 2026: Eligibility, Prerequisites & How to Qualify; here are the pieces that affect your study timeline.
The two main experience routes
- Registered apprenticeship: 8,000 on-the-job hours and 576 classroom hours, with completion of the program required for licensure.
- Approved postsecondary electrical program (PSEP): program completion plus 6,000 qualifying licensed work hours. Under rule 401.2(6)(f), eligible work counts once the program begins, so do not assume only post-graduation hours qualify.
Other routes and a conflict worth flagging
Existing Class B licensees and specified out-of-state licensees have their own routes under rule 401.2(6), and Class B status is not interchangeable with the examined Class A route. DIAL also publishes affidavits for a residential-route pathway (Residential Electricians and Residential Master Electricians with 4,000 qualifying commercial/industrial hours) and a 16,000-hour pathway that requires at least 4,000 hours within the preceding five years, 54 approved continuing-education hours, prescribed work categories and Iowa-master verification.
Coming from another state? Reciprocity requires an eligible agreement-state license held at least one year, a qualifying state examination and no failed Iowa electrical examination, plus additional Iowa requirements. If you have already failed an Iowa electrical exam, reciprocity may not be available to you, which is one more reason to take the first attempt seriously.
The Seven Official Content Headings
The Candidate Information Bulletin lists seven examination content headings for the journeyman exam. These are exam content areas, not preparation-curriculum headings, and the printed weights add up to 101% because of rounding, which PSI explicitly acknowledges. We keep the printed figures as published rather than adjusting them. Communication Systems appears in other outlines in the bulletin but is not part of the journeyman scope, so do not spend study time there. A full walkthrough is in IA-JE Exam Domains 2026: Complete Guide to All 7 Content Areas.
| Domain | Weight | Approx. scored items* |
|---|---|---|
| General Electrical Knowledge | 13% | about 10 |
| Wiring and Protection | 25% | about 20 |
| Wiring Methods and Materials | 19% | about 15 |
| Equipment for General Use | 19% | about 15 |
| Special Occupancies | 13% | about 10 |
| Special Equipment | 6% | about 5 |
| Special Conditions | 6% | about 5 |
*Rough planning estimates only, calculated by applying the printed weights to 80 scored items. Actual per-form distributions can differ.
Wiring and Protection (25%)
The largest heading and the one most likely to decide your result. Expect questions that combine conductor sizing, overcurrent protection, grounding and bonding, and the correction and adjustment factors that modify ampacity.
- Practice moving from a load to a conductor size to an overcurrent device without skipping the ampacity adjustment steps
- Know where grounding and bonding requirements live in the Code so you can find them in seconds
- Work through voltage drop and conductor derating until the process is automatic
Wiring Methods and Materials (19%)
Raceways, cables, boxes and fittings. These questions reward knowing which article governs each method and what the fill, support and securing rules are.
- Box fill and conduit fill calculations appear in many exam banks, so rehearse them with the actual Code tables
- Learn the permitted-uses and not-permitted lists for each wiring method
Equipment for General Use (19%)
Motors, transformers, panelboards, receptacles, luminaires and the equipment articles that govern them.
- Motor circuit sizing, with its separate rules for conductors, overload and short-circuit protection, is a classic trouble spot
- Review transformer overcurrent protection and panelboard requirements
General Electrical Knowledge (13%)
Fundamentals that underpin the rest of the exam: Ohm's law, power, series and parallel circuits, and general theory you will use in calculations.
- Be fast and accurate with basic formulas; these are the easiest points to protect
Special Occupancies (13%)
Hazardous locations, healthcare, assembly, and other occupancy-driven rules that modify the general requirements.
- Focus on how the special-occupancy chapter amends the general rules rather than memorizing every detail
Special Equipment and Special Conditions (6% each)
Treat these as two distinct headings with small individual weights. Special Equipment covers items such as signs, pools and similar installations; Special Conditions covers topics such as emergency and standby systems. Together they total roughly an eighth of the exam, so give them focused rather than extensive attention.
Making Your 2023 NEC Work for You
The exam permits either the 2023 NEC or the 2023 NEC Handbook. You must bring the 2023 edition; studying from an older edition will cost you points because rules and section numbering change between cycles. The rules on preparing your book are specific, so know them cold before test day.
| Allowed in your reference | Not allowed |
|---|---|
| Pre-highlighting | Writing in the book during the exam |
| Underlining | Loose or attached additional papers |
| Indexing | Temporary tabs |
| Permanent tabs | Ugly's and handwritten notes |
Use that allowance deliberately. Tab the entry points you will hit repeatedly: the definitions article, the Chapter 9 tables, the ampacity tables, the grounding and bonding sections, and the motor and transformer articles. Highlight the table headings you reach for during calculations. Because you can index and permanently tab, the preparation you do on the book itself is a real advantage over a candidate who walks in with a clean copy.
A lookup routine that saves minutes
- Identify the installation type or equipment named in the question.
- Go to the governing article via your tabs, not the index, whenever you already know the article.
- Confirm the specific section and any exceptions before choosing an answer.
- Check whether a special-occupancy or special-equipment article modifies the general rule.
A Domain-Weighted Study Schedule
Rather than a generic plan, weight your calendar by domain size and by dependency. Fundamentals come first because calculations in later domains rely on them, and Wiring and Protection gets the longest block because it is worth a quarter of the exam. Adjust the length to your sponsorship window; this example assumes about six weeks.
General Electrical Knowledge and book setup
- Review Ohm's law, power and circuit fundamentals
- Tab and highlight your 2023 NEC for the first time
Wiring and Protection
- Conductor sizing, ampacity adjustments, overcurrent protection
- Grounding and bonding lookups under time pressure
Wiring Methods and Materials plus Equipment for General Use
- Fill calculations, permitted uses, motors and transformers
Special Occupancies, Special Equipment, Special Conditions
- Focus on how special articles modify general rules
Full simulations and weak-area repair
- Two timed 88-question runs, then targeted review of misses
If you have less time, compress by trimming the review of your strongest domains, not by skipping Wiring and Protection. For a sense of where candidates tend to struggle and why, How Hard Is the IA-JE Exam? Complete Difficulty Guide 2026 is a useful companion, and the one-page reference in IA-JE Cheat Sheet 2026: One-Page Review of Must-Know Facts works well for the final days.
Building Full-Length Practice Simulations
Many practice resources stop at 80 questions, which matches the scored count but not the real experience. The actual sitting is 88 questions over 210 minutes, and the unscored items change your pacing and stamina. Build or choose simulations that match the true format: 88 items, a 210-minute clock, and your tabbed 2023 NEC open beside you.
- Use original questions. Practice items should be written to test the same skills, never copies of live exam content. Be wary of any source claiming to reproduce real questions.
- Time every run. Track how long lookup questions take versus calculation questions and set personal time ceilings per item.
- Review by domain. After each simulation, sort your misses by the seven headings so your next study block targets the weakest area.
- Practice the on-screen calculator. Decide in advance whether you will use the on-screen tool or a qualifying nonprogrammable calculator, and rehearse with that exact tool.
You can try timed sets on our Iowa journeyman electrician practice test and track your results by domain. Other providers exist, including JADE Learning, Tests.com, Classes4Contractors, Thompson Learning and 1ExamPrep, but coverage and current availability vary, so compare any course against the official content headings before you buy. For structured instruction beyond self-study, see IA-JE Training.
Retake Rules and Remediation
The first attempt matters more than it might seem, because Iowa attaches waiting periods and continuing-education requirements to repeated failures under rule 401.2(13). Knowing the ladder helps you appreciate why a prepared first sitting is worth the effort.
| Failed attempts | What the rule requires next |
|---|---|
| Two | Six-month wait and 12 approved continuing-education hours before two further attempts |
| Four | Another six-month wait and 12 hours |
| Six | Board petition required for further testing, plus an additional six-month wait |
Remember also that your Board approval covers two attempts or six months, so a retake may require fresh paperwork depending on timing. If you do miss, use your score report to identify which headings dragged you down and rebuild your plan around them rather than simply re-reading everything.
After You Pass: License Fee and Renewal
Passing the exam is the gateway, not the finish line. The full three-year journeyman license fee is $75 for the 2026-2028 cycle, with initial fees prorated by application month. A complete breakdown, including the exam fee and other costs, is in IA-JE Certification Cost 2026: Complete Pricing Breakdown.
For renewal, rule 403.201 requires 18 approved continuing-education hours per full three-year term, or six for each year or portion of a year in a shorter initial term. DIAL's archived Continuing Education Requirements handout, dated October 20, 2025, specified at least six NEC hours for the 2023-2025 term. That is historical guidance; it should not be read as a separately verified requirement for 2026-2028, so check current DIAL materials when your renewal approaches.

Frequently Asked Questions
There are 88 questions in total: 80 scored items with 180 minutes, plus eight unscored items with 30 additional minutes, for 210 minutes overall. You will not be told which items are unscored.
You need 70% on the scored items. This is a passing requirement, not a pass rate; official cohort pass-rate statistics were not verified for this article.
No. Only the 2023 NEC or 2023 NEC Handbook is allowed. Ugly's and handwritten notes are prohibited. You may pre-highlight, underline, index and use permanent tabs, but temporary tabs, loose or attached papers, and writing in the book during the exam are not permitted.
Board approval covers two attempts or six months. After two failures, rule 401.2(13) requires a six-month wait and 12 approved continuing-education hours before two further attempts, with the same pattern after four failures and a Board petition required after six.
Wiring and Protection, at 25%, is the largest of the seven content headings. Wiring Methods and Materials and Equipment for General Use follow at 19% each, so those three together account for the bulk of the exam.
