Licensing Steps

Missouri’s NASCLA electrical exam pathway is structured so candidates first work through the state’s qualification and application process, then schedule the NASCLA examination through PSI after approval. The Missouri Candidate Information Bulletin outlines these steps at a high level:

1. Request the application and instructions from the Missouri Division of Professional Registration, Office of Statewide Electrical Contractors (OSEC).
2. Complete and submit the application to OSEC for review and eligibility determination.
3. After approval, schedule the exam with PSI using the instructions provided after OSEC approval.
4. Pay the PSI examination fee when scheduling. The bulletin lists an examination fee of $125, and notes that exam fees are not refundable or transferable.

The bulletin also explains that candidate eligibility is valid for a defined period once approved, and exam scheduling is handled through PSI after approval by OSEC. Your “1 Package” is designed to keep your exam preparation aligned with that timeline so your studying, paperwork, and business setup progress together instead of competing for your attention.

State Requirements

Missouri’s statewide electrical contractor licensure requirements are defined in state regulation. In Missouri’s application rule for a statewide electrical contractor license, applicants must submit the division-provided application, pay applicable fees, and provide proof of key requirements, including:

• Liability insurance of at least $500,000 (submitted as a Certificate of Insurance issued by an insurance company authorized in Missouri).
• Bonds required by any political subdivision have been posted (when applicable to the jurisdictions where you work).
• A passing score on a division-approved examination.
• Qualifying education and/or experience meeting one of the listed pathways (examples below).

The regulation lists multiple qualifying pathways, including (but not limited to):

• 12,000 verifiable practical hours installing equipment and associated wiring; or
• 10,000 verifiable practical hours plus proof of an electrical journeyman certificate from a U.S. Department of Labor-approved electrical apprenticeship program; or
• 8,000 verifiable practical hours plus proof of an associate’s degree from a state-accredited program; or
• 4,000 verifiable practical hours supervising installations plus a qualified four-year electrical engineering degree; or
• A qualifying local Missouri political subdivision electrical contractor/master electrician license that has been current and active for six of the previous eight years (with verification requirements).

The same regulation also explains acceptable ways to document practical hours (such as W-2s with affidavits or notarized letters, affidavits from employers/others with firsthand knowledge, and other acceptable documentation), and notes that degrees must be verified by official transcripts.

Reference Books

Your package includes the core reference library aligned to the open-book exam’s approved materials. These references are not “nice-to-have”—they are the foundation of how you’ll answer questions under time pressure. Each title below is included with this package.

• Included Book: National Electrical Code, NEC, 2023
  The primary code reference for electrical installations, wiring methods, protection, equipment use, and code requirements commonly tested at the master/unlimited contractor level.

Important study note: Because this is an open-book exam, the goal is not to memorize entire books. The goal is to become highly skilled at finding the right section fast. Your course structure and study plan should emphasize navigation drills, index practice, and repeated timed lookups—so the references become tools you can use efficiently under pressure.

Test Information and Study Materials

PSI administers the exam via computer, and the Candidate Information Bulletin explains that you’ll see one question at a time, can mark and review questions within the time allowed, and you’ll receive your score after completion. The bulletin also describes an on-screen tutorial (up to 15 minutes) provided before the exam begins, and that tutorial time does not count against your exam time.

Because the exam is timed and open book, your best preparation is a blend of:

• Reference familiarity: Knowing how each book is organized, where key topics live, and what the index is best for.
• Timed practice: Simulating real pacing so “search time” doesn’t eat your score potential.
• Topic-based review: Studying the exam’s major content areas so you recognize what’s being asked before you start looking things up.
• Process and safety mindset: Contractor-level exams test professional judgment—especially around safety, planning, and code compliance.

This is exactly why an all-inclusive package matters. When your study tools, licensing support, and business setup tasks are coordinated, you spend less time managing the process—and more time building the skills the exam actually rewards.
