The R16 requires 75% to pass – the highest bar in the ICC electrical program. Generic prep won't get you there, especially prep that's built around an older code cycle. MCL builds exclusively around the R16, so you walk in current — with the codebook fluency and exam technique the Master exam demands.
The R16 runs on the 2023 NEC and is quickly becoming the standard Master electrician credential as jurisdictions update their testing requirements. Check the jurisdiction guide to confirm whether your city or county tests on R16 and which exam code they use locally.
The Master exam has a reputation for a reason. Pass rates nationally fall below 40%, and in some states, below 30%. It doesn't just test more code. It tests supervisory judgment, code interpretation, and planning-level thinking.
