Frequently asked questions
How is the Wisconsin Industrial Journeyman Electrician exam structured?+
One exam of 100 questions in 4 hours, open book, and you need 70%. Our blueprint weights motors, controls and transformers most heavily, with hazardous locations, grounding and wiring methods next.
Which code edition is the exam on?+
The 2023 NEC, as Wisconsin adopts it in SPS 316. The new code took effect September 1, 2026, and DSPS exam questions reflect it from October 1, 2026. Before that the exams tested the 2017 NEC, so older study material numbers many rules differently.
Is it open book? What can I bring?+
Yes. You may bring one binder holding SPS 305, SPS 316 and your own printed notes; the 2023 NEC or the NEC Handbook; and up to two bound reference books such as Ugly's, Ferm's, Tom Henry or Mike Holt. Practice or previous exams are not allowed as notes, and tabs are allowed only if they came with the book.
Who gives the exam, and what does it cost?+
The Wisconsin Department of Safety and Professional Services (DSPS). You apply through LicensE, then test at a DSPS paper-exam site or a Pearson VUE computer-based center in Wisconsin. The fees are $95 to Pearson and $30 to DSPS. You need 70% to pass.
How often do I renew?+
Wisconsin electrician licenses run four-year terms and expire June 30. The industrial journeyman electrician license needs 18 hours of continuing education each term.
What do I need before I can sit the exam?+
1,000 hours a year of industrial electrical work for five years. If you complete an industrial electrical apprenticeship instead, no exam is required.
