What to Expect on the Colorado Electrician Exam
Colorado has a statewide journeyman electrician license through the Department of Regulatory Agencies (DORA). The exam is administered by PSI: 90 questions, 240 minutes (4 hours), 70% passing score, and an exam fee of $78 initial, $73 retest (per the PSI bulletin). Colorado uses a hybrid open/closed book format: the first section is closed book, and the second section permits the NEC. This makes Colorado's exam distinctly different from most states that are fully open book. Candidates must be familiar with key NEC values, formulas, and wire sizing tables without needing the codebook, while also knowing how to navigate the NEC under time pressure during the open section. Colorado requires 8,000 hours of apprenticeship training and a completed application through DORA before scheduling the PSI exam. For exams administered on or after August 1, 2026, questions are based on the 2026 NEC. The most frequently tested articles include Article 220 (load calculations), Article 250 (grounding), Article 310 (conductors), and Article 430 (motors). Denver, Colorado Springs, Aurora, and Fort Collins are the major markets. Colorado's booming residential and commercial construction market drives strong demand for licensed journeymen. The practice questions below are aligned to NEC 2023 and the Colorado DORA PSI exam format.
