Idaho Electrician Exam Prep

Idaho’s Journeyman and Master Electrician exams are given by PSI. Each has 100 questions and a 4.5-hour limit. Both are open book, with the 2020 or 2023 NEC allowed.

Journeyman needs 70% to pass. Master needs 75%. Neither exam has a separate Idaho law section, so your score comes down to the NEC, theory and calculations. JCR teaches the 2020 NEC, so study and test with that edition.

Course fit: what JCR covers and what it does not
