You're right to be questioning the PSI practice exam's accuracy and scope. Here's a breakdown of what to expect, how the PSI practice compares, and how to prepare effectively

PSI Practice Exam vs. Real Exam:
Generally a good starting point, but not a perfect predictor

The PSI practice exam is designed to give you a sense of the types of questions you might encounter, the format of the exam, and the general knowledge areas tested. It's a valuable tool for identifying weak spots in your understanding of the NEC.

Varying Relevance

While it covers core NEC topics, its accuracy in replicating the actual difficulty level, phrasing, and specific content of your state's journeyman exam can vary. As you've experienced, it can include questions that are either too basic, outdated, or not directly related to the most crucial aspects of electrical work.

State-Specific and Ancillary Topics (The Gap)

This is the key area where the PSI practice generally falls short. It may not adequately cover:

State-Specific Amendments to the NEC

Many states adopt the NEC but then make amendments or addendums that directly impact electrical installations.

State Electrical Codes (if different from NEC)

Some states might have their own unique electrical codes that supersede the NEC in certain instances.

State Licensing Laws and Regulations

Rules about permitting, inspections, continuing education, and the scope of work a journeyman can perform.

OSHA Regulations

While OSHA covers workplace safety in general, some states may have additional or more specific OSHA regulations related to electrical work.

Accessibility Codes (ADA)

ADA impacts electrical design and installation, especially regarding signage, lighting, and receptacle placement.

Energy Efficiency Standards

These can influence lighting design, motor selection, and other electrical system components.

Resistor Color Codes, While Possible, Not Common

While you might see one question, most modern electricians aren't constantly relying on memorization.

Are These "Extra" Questions on the Real Exam? Yes, to varying degrees. Expect to see questions on topics outside the core NEC, but the emphasis will depend on your state. State Amendments are Crucial

You must know your state's amendments to the NEC. These are often the source of the most missed questions.

OSHA is likely

Expect some OSHA-related questions, especially those directly relevant to electrical safety (lockout/tagout, PPE, arc flash, etc.).

ADA/Accessibility

Likely a small portion but worth reviewing.

Energy Efficiency

Increasingly important, so expect some coverage.

How to Prepare for the State-Specific and Ancillary Topics


Your State's Electrical Board/Licensing Agency Website: THE PRIMARY RESOURCE! Downloadable Resources

Most state electrical boards have comprehensive websites. Look for:

Exam Content Outline/Candidate Information Bulletin

This is the most important document. It details the specific topics covered on the exam, the percentage of questions allocated to each area, and the references allowed during the test.

State Electrical Codes (if different from NEC)

Download and become familiar with the applicable code version and any state-specific addendums.

State Laws and Regulations Related to Electrical Licensing

Understand the rules you must follow as a licensed electrician in your state.

Permitting and Inspection Procedures

Understand the local processes.

Continuing Education Requirements

Know what's expected of you to maintain your license.

Contact Information

If you have specific questions, don't hesitate to contact the licensing agency directly.2.

State-Specific Study Guides and Courses



Online Courses

Search for online courses specifically tailored to your state's journeyman exam. These courses often focus on state amendments, licensing laws, and relevant regulations. Some may offer practice questions that are more reflective of the actual exam.

Local Electrical Training Schools

Many local vocational schools or IBEW chapters offer exam preparation courses that cover state-specific information.3.

OSHA Resources



OSHA Website (osha.gov)

Familiarize yourself with OSHA's electrical safety standards (29 CFR 1926 Subpart K for construction). Pay attention to topics like lockout/tagout, personal protective equipment (PPE), arc flash hazards, and safe work practices.

OSHA Training

Consider taking an OSHA 10 or 30-hour construction safety course.4.

ADA/Accessibility Resources



ADA Standards for Accessible Design (www.ada.gov)

Review the sections related to electrical requirements, such as receptacle height, signage, and lighting.

Key Study Strategies



Prioritize the Exam Content Outline

Use it as your roadmap. Focus your studying on the topics and areas with the highest percentage of questions.

Read the State's Amendments Carefully

Understand how they modify or supplement the NEC requirements.

Practice, Practice, Practice

Work through as many practice questions as you can find. Analyze your mistakes and understand why you got the answers wrong. Create your own flashcards to memorize key concepts and formulas.

Time Management

Practice taking timed practice exams to improve your speed and accuracy.

Reference Materials

If you're allowed to bring reference materials into the exam (e.g., the NEC), become extremely familiar with their organization and how to quickly find the information you need.

In Summary:

The PSI practice exam is a good starting point, but don't rely on it solely for your preparation. Focus on the key areas: State amendments, OSHA, ADA/Accessibility, and anything that is not in the NEC but is mandated by the state. The extra information found on the state electrical board web site should be all you need.Good luck with your exam! Flag for review
