The Ohio journeyman electrician exam, and what the state actually licenses

Last verified 2026-07-25

If you came here for the Ohio journeyman electrician exam, here is the situation: Ohio does not issue a state journeyman license.

The Ohio Construction Industry Licensing Board, under the Department of Commerce, licenses commercial electrical contractors at the state level. Journeyman licensing in Ohio is municipal, so which exam you sit and what it requires depends on the city you are working in.

Two different paths, and people conflate them constantly:

• Journeyman: your city or local licensing authority. Requirements vary between them.
• Commercial electrical contractor: that is the state exam, through OCILB, and that is what this page covers.

What the OCILB electrical contractor exam looks like

From the PSI/OCILB Contractor Trade Examinations candidate information bulletin:

• 100 scored questions plus 10 unscored pretest items, 4 hours. You will not know which ten do not count, so treat everything as live.
• You need 70% to pass. Ohio states its pass mark right in the bulletin, so you are not guessing at the target.
• It is open book. The bulletin says it outright: "This examination is OPEN BOOK."
• You bring your own reference. "Candidates may also bring their own reference to the examination center."
• The NEC edition is 2023, and code questions are scored "only on the edition of the Code book that is listed."
• The vendor is PSI.

The content is published as a breakdown, which is genuinely useful for allocating study time:

Service, feeders and branch circuits is the biggest single block. If you are triaging study time, start there.

Ohio lets you bring the NEC Handbook, and its neighbors in this series do not

This is the one that surprises people who have tested elsewhere.

The Ohio reference list permits "NFPA 70 – National Electrical Code, and/or The National Electrical Code Handbook, 2023." And the bulletin spells out that you can use both: "Either reference on its own is sufficient; however, candidates are permitted to use both references."

That is worth knowing, because it is not the common answer. Of the states in this series with verified reference rules on the Handbook, Ohio is the only one that permits it. Texas, Michigan and North Carolina all prohibit it. The Handbook is the code plus commentary, diagrams and explanation, so being allowed to carry it into an open-book exam is a meaningful advantage, and it is one you only get in some jurisdictions.

Ohio also allows Ugly's Electrical References, 2023.

If you have been told "the Handbook is never allowed on electrical exams," that is a rule from somewhere else being repeated as though it were universal. In Ohio it is wrong.

What you can do to your book in Ohio

Among the states in this series, Ohio sits in the middle. More permissive than Michigan, stricter than North Carolina.

• Marking beforehand is allowed, including indexing. "Reference materials may be highlighted, underlined, and/or indexed prior to the examination session." Note that "indexed" is permitted, and Ohio does not restrict tabs to publisher-made ones the way Texas does.
• But you cannot write in them. "However, references may not be written in."
• And getting caught during the exam is serious. "Any candidate caught writing in the references during the examination will have the references confiscated and will be reported to the department." Confiscated, then reported.
• Nothing extra comes in. "Candidates are not permitted to bring in any additional papers (loose or attached)."

Confirm this against the current bulletin before test day. Rules get revised and the bulletin is the authority, not this page. Pull it here: PSI OCILB Contractor Trade Examinations Candidate Information Bulletin.

What actually decides it

Four hours for 110 questions is just over two minutes each, and that is a real clock. Being allowed to bring the Handbook helps, but only if you can find things in it. A second book you cannot navigate is a second book you are carrying for nothing.

The skill is navigation speed, in three parts:

1. Index or table of contents, decided instantly. Some questions hand you a term and the index is fastest. Others are really asking which article governs a situation, and the chapters get you there quicker. Two seconds, not forty.
2. Landing on the actual rule. The right article is not the right subsection. Close is slow.
3. Following cross-references without losing your place. The code sends you elsewhere constantly, go see 310.16 and now you are in a table, and the hops compound.

Ohio's published content outline makes this easier to drill deliberately. You know 16 questions are coming from service, feeders and branch circuits. Practice finding those rules until it is automatic.

How to practice it

Most practice sites do the same unhelpful thing: you miss one, they show you the answer. It feels like studying. It is not, because on test day nobody shows you anything, they hand you a book and start a clock.

That is why I built electricianstudyguide.org while going through school myself.

• 250+ original questions on the 2023 NEC, the same edition Ohio is testing on, and it will not give you the answer. Every question points at a real rule you have to go look up.
• A built-in tutor, Sparky, who will not hand it over either. He walks you through running the rule down in the index instead of just telling you.
• A toolkit with conduit bending, ohms law, trig, and a motor lab. I use the bender in class myself.
• Tap any term for its definition, have questions read aloud, works on your phone, nothing to install.

Nothing here promises you a pass. What it does is make you fast at finding rules, which is what an open-book exam with a clock is actually testing.
