Exam Details

The Iowa Journeyman Electrician examination is administered through PSI for the Iowa Electrical Examining Board. Candidates must submit a license application and testing sponsorship request to the Board. After the Board approves the request, the candidate receives authorization to test and then schedules the examination through PSI.

The Iowa Journeyman Electrician exam is listed with 80 scored items, 180 minutes of testing time for scored items, and a required passing score of 70%. The exam may also include 8 non-scored items with an additional 30 minutes. Non-scored items are used for examination development and do not count toward the final score.

The Iowa Journeyman Electrician content outline includes 13% General Electrical Knowledge, 25% Wiring and Protection, 19% Wiring Methods and Materials, 19% Equipment for General Use, 13% Special Occupancies, 6% Special Equipment, and 6% Special Conditions. These categories cover a wide range of practical and code-based electrical knowledge.

This exam outline shows why students should study across the full range of electrical topics. Wiring and protection, wiring methods and materials, and equipment for general use make up a large part of the examination, but smaller categories can still affect the final score. A candidate may need to interpret a wiring method requirement, size conductors, apply overcurrent protection rules, understand equipment requirements, identify special occupancy rules, or solve a calculation.

Because the test is timed, candidates should prepare for both accuracy and speed. Iowa’s journeyman exam gives candidates a limited amount of time to answer code-based, trade-based, and calculation-based questions. Strong preparation should include topic review, NEC navigation, and repeated problem practice instead of relying on field experience alone.

Open Book Test

The Iowa Journeyman Electrician exam is an open book examination because approved reference material is allowed in the examination center. The current PSI candidate bulletin lists the National Electrical Code, 2023 edition, or the National Electrical Code Handbook, 2023, as allowed references for the journeyman examination.

This product is based on the 2026 NEC and includes the National Electrical Code 2026 Paperback for updated study, code navigation practice, and calculation-based preparation. Candidates should follow the current Iowa Electrical Examining Board and PSI testing instructions for the code edition and reference material used on exam day.

Open book testing still requires serious preparation. A code book is only helpful when the student knows how to use it. Candidates need to understand the subject being tested, locate the correct article or table, read the rule carefully, and apply the requirement under timed conditions. Slow reference navigation can make even familiar electrical topics difficult during an exam.

The National Electrical Code 2026 Paperback included in this combo gives students a physical code reference for building those skills during study. Students can practice locating common journeyman exam subjects such as conductor ampacity, wiring methods, services, feeders, branch circuits, grounding electrode systems, equipment grounding conductors, bonding jumpers, raceways, boxes, motors, overcurrent protection, lighting, equipment requirements, special occupancies, and calculation-related provisions.

Iowa’s PSI reference rules allow approved references to be highlighted, underlined, and indexed before the examination session. References may not be written in before or during the exam, and additional loose or attached papers are not permitted with approved references. References may be tabbed or indexed with permanent tabs only. Candidates should prepare their exam references according to the active PSI bulletin.

Licensing Steps

Iowa journeyman electrician candidates begin by meeting the state’s qualification path for the license. The Class A Journeyman path is tied to completion of a qualifying electrical training program, such as a registered apprenticeship training program, or an approved equivalent post-secondary electrical program recognized by the Electrical Examining Board.

After meeting the required training path, the candidate submits the license application and testing sponsorship request to the Iowa Electrical Examining Board. The Board reviews the application and determines whether the applicant is approved to test. A license fee is not required until after the test is passed.

Once approved, the candidate receives an authorization to test letter. The candidate then contacts PSI, pays the examination fee, and schedules the journeyman electrician exam. The authorization letter is valid for two examination attempts or six months. Candidates who do not pass after two attempts must contact the Board for another authorization and follow the Board’s rules.

After passing the exam, the candidate contacts the Iowa Electrical Examining Board for instructions regarding the license. Passing the exam is a major step, but the licensing process is not complete until all Board requirements are satisfied and the license is issued.

A strong licensing plan begins early. Candidates should keep training records organized, complete required program requirements, review the exam outline, and build a steady study routine. Journeyman exam preparation is usually strongest when students study over time through trade review, code navigation, and calculation practice instead of waiting until the exam date is close.

State Requirements

Iowa issues state electrical licenses through the Iowa Electrical Examining Board. The Class A Journeyman Electrician license path requires successful completion of an apprenticeship training program registered by the United States Department of Labor’s Bureau of Apprenticeship and Training, or completion of a Board-recognized equivalent training pathway.

The Iowa Electrical Examining Board also recognizes some post-secondary electrical programs as equivalent pathways for journeyman licensing. For an approved post-secondary electrical program path, students may complete an approved program and documented on-the-job training before becoming eligible to be sponsored for the journeyman electrician exam.

A commonly used Iowa training model includes 8,000 hours of qualifying electrical preparation. Under an approved post-secondary electrical program path, the 8,000-hour total may include 2,000 hours from the approved program and 6,000 hours of documented on-the-job training. Candidates should follow the exact pathway accepted by the Iowa Electrical Examining Board for their license type.

Iowa also has different license classifications, and students should make sure they are preparing for the correct credential. A Class A Journeyman license is different from a Class B license, a residential electrician license, a master electrician license, a residential master license, and an electrical contractor license. Each classification has its own scope and requirements.

For candidates using this combo, the goal is to build the knowledge expected of an Iowa journeyman electrician. That includes electrical installation knowledge, practical safety awareness, code understanding, calculation ability, and the confidence to apply electrical rules to real-world installation questions.

Test Information and Study Materials

Iowa journeyman electrician preparation should include a broad review of electrical trade topics and code-based installation requirements. Important study areas include general electrical knowledge, wiring and protection, wiring methods and materials, equipment for general use, special occupancies, special equipment, special conditions, grounding and bonding, services, feeders, branch circuits, conductors, raceways, boxes, motors, lighting, safety, and calculations.

The 2026 Iowa Journeyman Electrician Study Guide helps students organize these subjects into a practical study plan. Instead of studying random code sections without direction, candidates can work through one topic at a time and connect that subject to real electrical work. This approach helps students understand how exam questions may present jobsite conditions, code rules, and practical installation choices.

The 2026 Electrician Calculations Study Guide supports the math side of preparation. Electrical calculations often require several steps, and students should practice them repeatedly. Useful calculation areas include Ohm’s law, power formulas, conductor sizing, voltage drop concepts, box fill, raceway fill, load calculations, service and feeder calculations, branch circuit calculations, motor calculations, transformer calculations, and overcurrent protection applications.

Calculation study should be active. Students should work problems by hand, write formulas clearly, identify known values, convert units where needed, and check whether the answer makes sense. Reading a solved example may introduce a concept, but repeated practice builds speed and confidence. This is especially important for timed electrical exams because calculation questions can take longer than direct code lookup questions.

The National Electrical Code 2026 Paperback should be used throughout the study process. Students should practice locating definitions, article sections, tables, notes, and exceptions. They should also learn how related code topics connect. A conductor question may involve ampacity, adjustment factors, terminal temperature limitations, overcurrent protection, and equipment rules. A grounding question may involve grounding electrodes, bonding jumpers, equipment grounding conductors, services, and fault-current paths.

A balanced study schedule may rotate between trade review, NEC navigation, and calculation practice. One session might focus on wiring and protection. Another might focus on wiring methods and materials. Another might involve conductor sizing or box fill calculations. Another might involve locating special occupancy or equipment rules in the NEC. This rotation helps candidates prepare across the full range of journeyman-level electrical knowledge.

Students should also include timed practice. Since the Iowa Journeyman Electrician exam is timed and open book, pacing matters. Practice sessions should help candidates learn when to look up a rule, when to calculate, when to move forward, and how to manage the exam without spending too long on one question.
