Wisconsin Electrician License Guide: Exam Requirements, Fees & NEC Edition (2026)

Wisconsin's Department of Safety and Professional Services (DSPS) runs one of the more specific open-book exam formats in the country — everything has to fit in a single three-ring binder, in a precise combination of state code, printed notes, and named reference books. And the NEC edition on DSPS's own current exam page may surprise you: it's still the 2017 edition, not 2023. Here's exactly what DSPS's site confirms today.

Quick Answer

Who Regulates Electrical Work in Wisconsin

The Department of Safety and Professional Services (DSPS) licenses electricians statewide under Wis. Stat. § 101.862 and Wis. Admin. Code chapters SPS 305 and SPS 316. DSPS's own site is direct about the legal requirement: "no person may install, repair or maintain electrical wiring unless the person is licensed as an Electrician by the Department or unless the person is enrolled as a Registered Electrician by the Department." All initial, reinstatement, and renewal applications now go through DSPS's online LicensE portal rather than paper forms.

Apprentice, Journeyman, and Master

Per Wis. Admin. Code § SPS 305.40, a Journeyman Electrician or Registered Electrical Apprentice must work "under the general supervision of a person who holds a license as a licensed Master Electrician or a registration as a Registered Master Electrician." There's a notable carve-out: a Journeyman or Apprentice can instead work under a Residential Master Electrician, but only for wiring tied to dwellings, dwelling units, and their detached accessory structures — garages, carports, gazebos, and swimming pools. That means a Residential Master's supervisory authority is narrower than a full Master's, scoped specifically to residential-adjacent work.

The Exam Format

Per DSPS's own exam page: "The exam is open book, and the passing score is 70%." The exam is delivered through Pearson VUE. DSPS's page doesn't post a fixed question count or time limit directly — for those specifics and current test dates, DSPS refers candidates to its separate Trades Examination Information page.

The NEC Edition — and Why It's Not 2023

This is the honesty flag worth knowing before you buy a code book: DSPS's current, live exam-reference page lists "2017 National Electrical Codebook (NEC) or Handbook" as the approved code reference — not the 2023 or even 2020 edition. This isn't an oversight on an old page; DSPS's Journeyman Electrician landing page explains the history directly: "as of August 1, 2018 an updated Wis. Admin. Code ch. SPS 316 will go into effect. While the requirements in the 2011 NEC will be effective until Jan. 1 of 2020 for one and two family dwellings, all Electrical Exams will change to reflect the updated Wis. Admin. Code ch. SPS 316 and the 2017 NEC." That transition happened, and the 2017 NEC has apparently remained the tested edition since. Some third-party test-prep sites describe a pending or recent move to the 2023 NEC — we could not confirm that transition on DSPS's own current pages. Confirm the exact edition directly with DSPS before buying a code book, especially if you're testing soon.

Exactly What Goes in the Binder

Wisconsin's reference rules are unusually specific about format, not just content. Per DSPS: "Pearson VUE and DSPS exam locations will ONLY allow the following four reference items into the exam":

1. One binder containing Wis. Admin. Code § SPS 305, § SPS 316, and printed notes — all three-hole punched and bound together.
2. The 2017 National Electrical Codebook (NEC) or Handbook.
3. Up to two printed, bound reference books — DSPS names Ugly's, Ferm's Fast Finder Index to the NEC, the Tom Henry series, and the Mike Holt series as examples.

Tabs are allowed only if they came with a bound code book, or as three-ring paper dividers with tabs. Loose papers, removable tabs, sticky notes, and paperclips are explicitly listed as not allowed. Practice exams or previous exams don't count as "notes" and are barred even if bound into the approved binder.

Frequently Asked Questions

Who administers the Wisconsin electrician exam?

Pearson VUE, per DSPS's own exam information page — not PSI, despite some third-party sites naming PSI as the vendor.

What NEC edition does Wisconsin's electrician exam test?

DSPS's own current exam page lists the 2017 NEC. Some aggregators claim a newer edition is in use or coming soon, but we could not confirm that from DSPS's own site — verify directly before assuming otherwise.

Is the Wisconsin electrician exam open book?

Yes, with a specific format: one binder of state code plus printed notes, the bound NEC, and up to two named reference books. Loose papers, sticky notes, and removable tabs are not allowed.

Can a Journeyman work under a Residential Master Electrician?

Yes, but only for wiring connected to dwellings and their accessory structures like garages and pools — a Residential Master's supervisory scope is narrower than a full Master Electrician's.

Study Materials

Because DSPS's own current exam page names the 2017 NEC specifically — not the 2023 edition our catalog stocks — we're not recommending a specific code book bundle here. Confirm the exact edition DSPS is testing on your scheduled date before buying, since testing on the wrong year's code could genuinely cost you points on code-specific questions.
