NERC System Operator Certification

NERC (North American Electric Reliability Corporation) certifies the system operators who run the bulk power system from control centers across North America. There are four computer-based multiple-choice exams, delivered by Pearson VUE: Reliability Coordinator Operator (RC) and Balancing, Interchange, and Transmission Operator (BT), each 140 questions of which 120 are scored, with a cut score of 92; and Transmission Operator (TO) and Balancing and Interchange Operator (BI), each 120 questions of which 100 are scored, with a cut score of 76. Every exam includes 20 experimental questions that do not count. The exam takes 3 hours plus a 15-minute tutorial. Content outlines, effective 1 June 2023, set the questions per area across six domains: Resource and Demand Balancing, Transmission, Emergency Preparedness, Emergency Response, Contingency Analysis and Reliability, and Communications and Data. NERC lists the Reliability Standards (BAL, COM, EOP, FAC, INT, IRO, PRC, TOP, VAR) and the NERC Glossary among the references. A pass gives a credential valid for three years, maintained with NERC continuing education hours; a candidate who fails waits 42 calendar days before the next exam.
