The G16 requires 75% to pass – the highest bar in the ICC electrical program. Generic prep won’t get you there. MCL builds exclusively around the G16, so you walk in with the codebook fluency and exam technique the Master exam demands.
The G16 runs on the 2017 NEC and is the most widely accepted Master electrician credential in the ICC program. Check the jurisdiction guide to confirm whether your city or county requires it and which exam code they use locally.
The Master exam has a reputation for a reason. 1 Where pass rates are tracked, they consistently land below 40% –– and in the toughest jurisdictions, closer to 20%. It doesn’t just test more code. It tests supervisory judgment, code interpretation, and planning-level thinking
