Exam Overview

The Texas Journeyman Industrial Electrician exam consists of 60 multiple-choice questions that you must complete within 180 minutes (3 hours). You need to score at least 70% (42 correct answers out of 60) to pass. The exam is administered by PSI Services and is based on the 2023 National Electrical Code (NEC).

On test day, you'll take the exam at a PSI testing center using a computer-based format. The questions are designed to test your practical knowledge of electrical theory, code requirements, and real-world applications specific to industrial electrical work. Unlike residential electrician exams, this test focuses heavily on industrial equipment, motor controls, and the unique safety considerations found in industrial environments.

You're allowed to bring a calculator and reference materials, including your copy of the NEC 2023. This is an open-book exam, which means knowing how to quickly navigate the code book is just as important as understanding the electrical concepts. Many test-takers find that proper preparation with tabs and highlighting can significantly improve their performance on exam day.

Essential Study Materials

Success on the Texas Journeyman Industrial Electrician exam requires the right study materials and preparation tools:

Required Reference:
The NEC 2023 is your most important study tool and the only reference you're allowed to use during the exam. This National Electrical Code contains all the requirements you'll need to answer exam questions. Make sure you get the 2023 edition, as the exam is specifically based on this version.

Organization Tools:
Redi-Tag Permanent Colored Tabs are essential for organizing your NEC. These permanent adhesive tabs help you quickly locate important articles and sections during the exam. With 100 tabs in 5 assorted colors, you can color-code different topics like motors, feeders, and safety requirements. The strong permanent adhesive ensures your tabs stay put even with heavy use.

Study Aids:
Sharpie Highlighters are perfect for marking important code sections and key requirements. This 12-pack includes multiple colors so you can develop a highlighting system that works for you. The narrow chisel tip is great for highlighting specific text without covering too much information.

These tools aren't just for studying – they're investments in your exam success. A well-organized NEC with proper tabs and highlighting can save you precious minutes during the exam, allowing you to find answers quickly and confidently.

Proven Study Tips
