Ohio Contractor License Exam Prep

Ohio contractors are licensed by the Ohio Construction Industry Licensing Board (OCILB). Most classifications sit a trade paper plus Law & Business. Need only the business paper? It is sold standalone. If you buy a Ohio classification that sits that exam, that paper is 75% off where we offer it.

Confirm question count, time, open-book rules, and passing score on the live board bulletin before you sit. We do not publish a single Q-count for every classification on this page, and we do not guarantee a passing result.

Getting your Ohio contractor license? Contractor Pathway offers an original, exam-focused study guide and four full-length practice exams for every Ohio classification that requires a state board exam — currently 4 courses across Electrical, Plumbing and HVAC / Mechanical. Choose your classification below and study with 30-, 60-, or 90-day access at $99, $129, and $169. Many Ohio classifications also require passing a separate Business & Law exam — and that course is 75% off with any trade course in your cart for the matching term.

Always confirm the current code edition, experience requirements, fees, and passing score with the board and testing vendor before you schedule. Contractor Pathway is an independent exam-prep provider and is not affiliated with any Ohio board or testing vendor.

How to get licensed in Ohio

Every figure below comes from the Ohio Construction Industry Licensing Board’s own examination application and the PSI candidate information bulletin it issues. Confirm current fees and code editions with the Board before you apply — requirements change.

  1. Meet the five-year experience requirement. OCILB requires that you have been a tradesperson in the trade you are applying for “for not less than five years immediately prior to the date of application.” You must be at least 18, a U.S. citizen or legal alien, and free of a disqualifying offence under S.B. 337. Two alternatives exist: an Ohio registered professional engineer with three years of business experience in that trade, or five years as an Ohio government inspector in the trade.
  2. Document it four ways. The application asks for the last five consecutive years of tax documents (W-2s or Schedule C) and one of the following: a minimum of one permit for each of the last five years pulled by the licensed contractor you worked under; a current Journeyman’s card in the trade; a certificate of completion of an apprenticeship approved by the State of Ohio or the U.S. Department of Labor; or proof of 40 hours of continuing education in code from an OCILB-approved training agency, taken live or virtually — self-guided courses are not accepted for licensing. Sewer service, water service, gas service and drain cleaning permits do not count toward the permit route.
  3. Apply and clear the background check. The examination application carries a $25 fee payable to Treasurer — State of Ohio. Once the Board approves you, a BCI and FBI background check is required before you sit the exam. Board approval is valid for one year.
  4. Pass both exams. Ohio requires two: the Contractor’s Business and Law exam — 50 scored questions, 2 hours, 70% to pass — and a trade exam for your field. The Electrical, HVAC and Plumbing trade exams are each 100 scored questions over 4 hours, also 70% to pass. Both are open book and delivered by PSI at $69 per exam. You take the Business and Law exam once every three years, not once per trade. Fail a portion and you must wait 60 days to retake it; you may test up to five times a year.
  5. Get licensed and insured. After passing both sections you send your examination results, a $25 check, and proof of at least $500,000 contractor liability insurance. Your insurance and licence must both be assigned to a “contracting company” as defined in Ohio Revised Code 4740.01(C).
  6. Renew with ten hours of continuing education a year. ORC 4740 requires that a licensee accrue ten hours of continuing education courses per year, and that total is the aggregate for every licence you hold — holding three licences does not mean thirty hours. Within it, no specialty section’s curriculum may require more than five hours per year in specific course requirements. Confirm current renewal fees with the Board before you budget, and note that renewal is handled by the specialty section that licenses your trade.

Choose your Ohio classification

Each course includes a comprehensive study guide — often 10,000 words or more — worked calculations, code-section breakdowns, common exam traps, a glossary, and a 30/60/90-day study plan — plus four full-length practice exams matched to the topic weightings of the Ohio test.

Ohio contractor licensing — FAQ

Does Ohio license general contractors?

Not at the state level. The Ohio Construction Industry Licensing Board (OCILB) issues statewide licenses only for the commercial trades – Electrical, HVAC, Refrigeration, Plumbing, and Hydronics. Residential construction is regulated by local jurisdictions.

What exams does Ohio require?

Two PSI exams: a Business and Law exam plus a trade-specific exam for your field. Both are multiple-choice, and you must pass both to be licensed.

What is the format and passing score in Ohio?

The OCILB exams are open book with a 70% passing score. The trade exam is 100 scored questions over four hours; the Business and Law exam is 50 scored questions over two hours. Confirm the current references in the PSI candidate information bulletin.

Which Ohio licenses do you build courses for?

The OCILB commercial trades that require a state exam – electrical, HVAC, refrigeration, plumbing, and hydronics. For residential general work, check your local jurisdiction, since Ohio does not issue a state residential GC license.

How long should I study for the Ohio exam?

Most candidates do well on a 30-, 60-, or 90-day plan depending on experience, which is why we offer access at all three terms ($99 / $129 / $169). Each guide includes a day-by-day study plan.
