How to Get Licensed
Step 1: Enroll in Registered Apprenticeship Program
Find an approved electrical apprenticeship program through Missouri Division of Professional Regulation or a union local (IBEW). Programs require high school diploma/GED, pass aptitude test, and commitment to 4-5 year program. Apprentices work under journeyman supervision and attend 144 hours classroom instruction annually covering NEC code, safety, math, and theory.
Step 2: Complete 8,000 Hours On-the-Job Experience
Work full-time under licensed journeyman or master electrician. Hours must be documented and verified by employer. Track all work: residential wiring, commercial systems, troubleshooting, panel work, grounding, etc. Roughly 2,000 hours per year means 4-5 year apprenticeship. Keep detailed logs; audits happen.
Step 3: Pass Classroom/Technical Instruction
Complete 144 hours of code training, typically 4 hours/week during apprenticeship. Focus on current NEC (2023 adopted in St. Louis), Missouri electrical code amendments, grounding/bonding principles, and safety. Classroom is mandatory; cannot test without completion certificate from program.
Step 4: Apply for Journeyman Exam
Submit completed apprenticeship record, classroom hours, and experience verification to Missouri Division of Professional Regulation. Application fee ~$200-300. DPR reviews documentation (2-4 weeks). Once approved, schedule exam through Pearson/PSI testing centers in Missouri. Exam covers code, theory, math, and safety (100+ questions, 4-hour test).
Step 5: Pass Journeyman Exam and Receive License
Exam score typically reported within 3-5 business days. Passing score 70%+. Upon passing, DPR issues Journeyman Electrician license valid 3 years. You can now work independently, supervise apprentices, and sign off on residential/commercial installations. License renewal requires 24 continuing education hours every 3 years and $50-75 renewal fee.
