What to Expect on the Illinois Electrician Exam
Illinois has no statewide electrician license. The Illinois Department of Financial and Professional Regulation (IDFPR) does not license electricians. Licensing is handled at the local level, and Chicago is by far the largest and most significant jurisdiction in the state. Chicago's individual credential is the Supervising Electrician license, issued by the Chicago Department of Buildings with the exam administered by Continental Testing Services. The exam is open book with the Chicago Electrical Code, which is based on the 2017 NEC with city amendments. Candidates must be at least 21 years old with at least 2 years of qualifying electrical experience. Question counts and fees change periodically, so confirm the current exam format and fee with Continental Testing Services before scheduling. The exam draws heavily from Article 220 (load calculations), Article 250 (grounding and bonding), Article 300 (wiring methods), and Article 430 (motors). Chicago's exam is known for testing Chicago-specific code amendments alongside the national code, so candidates need to be familiar with both. Outside Chicago, requirements vary by city: Rockford, Aurora, Naperville, and Springfield each have separate licensing programs. The NEC 2023 practice questions below cover all topics on the Chicago Continental Testing Services exam.
