OH-REF Exam Dates 2026: Testing Windows, Deadlines & Scheduling

How OH-REF Testing Actually Works in 2026

If you're searching for fixed "OH-REF exam dates" the way you might for a bar exam or a standardized college test, it helps to understand how the Ohio Refrigeration Contractor License Exam is actually delivered. The Ohio Construction Industry Licensing Board (OCILB), part of the Ohio Department of Commerce's Division of Industrial Compliance, does not administer the exam itself. Instead, it contracts with PSI, a computer-based testing provider, to deliver both the trade examination and the separately required Contractor's Business and Law examination.

Because testing is computer-based rather than paper-and-pencil administered on set dates a few times a year, there is no single national "OH-REF testing window" you need to circle on a calendar. Instead, candidates who have met OCILB's eligibility requirements schedule their own appointment at a PSI test center, typically choosing from available slots throughout the year. This matters for planning purposes: your personal "exam date" is really a target you set once your application is approved, not a date imposed by the state.

Registering for Your PSI Testing Appointment

Once OCILB approves your eligibility to sit for the Ohio Refrigeration Contractor trade examination, you'll register directly with PSI to select a test date and location. Each examination attempt - whether it's your first sitting or a retake - carries a $69 fee paid to PSI. Keep in mind that the trade exam and the Business and Law exam are charged and scheduled as separate appointments, so candidates budgeting for testing should plan for two distinct $69 charges if both exams are still outstanding.

Testing is open-book, but that doesn't mean walk-in-and-wing-it. PSI's candidate bulletin (updated February 7, 2024) specifies approved references, including the 2024 Ohio Mechanical Code and Modern Refrigeration and Air Conditioning, 22nd edition. You're permitted to bring these approved texts with advance highlighting, underlining, and tabbed indexing already in place - but handwritten notes or loose supplemental papers are prohibited at check-in. If you plan to rely heavily on your references during the exam, build time into your pre-scheduling prep to organize and index them properly; this is covered in more depth in the OH-REF Study Guide 2026: How to Pass on Your First Attempt.

Application Timeline: From Eligibility to Test Day

Before you can even think about picking a PSI date, you need to clear OCILB's eligibility gate. The standard path requires candidates to be at least 18 years old, be a U.S. citizen or hold lawful status, and document five years of trade experience immediately preceding the application. There are two alternative paths as well: holding an Ohio professional engineer license paired with three years of trade construction-business experience, or five years of service as an Ohio governmental trade inspector.

Applicants must submit experience documentation and complete BCI/FBI background checks, which realistically adds weeks to your timeline before you're cleared to test - not something you finalize the week before a desired exam date. The application fee is $25. Because background checks and documentation review aren't instantaneous, candidates who want to test early in 2026 should submit paperwork well ahead of their target month rather than assuming same-week turnaround. A full breakdown of who qualifies and how to document experience is available in OH-REF Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Trade Exam vs. Business and Law Exam Scheduling

Ohio requires refrigeration contractor candidates to pass two separate examinations, and understanding their formats helps you schedule study time and testing appointments realistically.

The trade exam totals 70 administered questions (60 scored, 10 unscored pretest items you won't be able to identify during the test), while Business and Law totals 55 administered questions (50 scored, 5 pretest). Both require a 70% passing score. Since these are scheduled as independent PSI appointments with independent $69 fees, many candidates choose to sit for Business and Law first or last depending on which content feels more comfortable - there's no OCILB rule dictating sequence. For a deeper look at exactly how the passing threshold is calculated, see OH-REF Passing Score 2026: Exactly What You Need to Pass.

What to Expect on Test Day

The trade exam's 60 scored questions are distributed across five domains, and knowing this allocation helps you decide how much time to allot per section mentally, even though PSI doesn't force you to move domain-by-domain in order:

On test day, the computer-based format means questions appear onscreen, and any calculations are done using only PSI's onscreen calculator - outside calculators, phones, or personal devices aren't permitted. Bring your approved, pre-indexed references since the exam is open-book, but remember that handwritten notes and extra papers stay outside the testing room.

If You Fail: Retest Waiting Periods and Annual Limits

Scheduling isn't just about your first attempt - it's about planning for the possibility of a retest, too. If you don't pass a portion of the exam, Ohio's rules require a 60-day wait before you can retest that section. PSI also caps candidates at five retests per year across the testing cycle.

This waiting period has real scheduling implications for anyone targeting a specific licensing deadline in 2026. If you fail the trade exam in, say, early spring, you're not eligible to sit again until roughly two months later - and each retest attempt costs another $69. Building a buffer into your timeline, rather than assuming a pass on the first try, protects you from missing a target start date for contracting work. For context on how many candidates typically need more than one attempt, see OH-REF Pass Rate 2026: What the Data Shows.

Building a Study Calendar Around the Domain Weights

Because you control your own PSI scheduling, you can reverse-engineer a study calendar that matches how the trade exam actually weights content. A simple approach is to allocate study weeks proportionally to scored-question counts rather than spreading time evenly across all five domains.

Notice that Domain 1 and Domain 4 alone account for 33 of the 60 scored questions - more than half the exam. That's a strong argument for front-loading your review there rather than treating all five domains as equally important. A full-length Ohio refrigeration contractor practice test can help you confirm which domains still need work before you lock in a test date.

After You Pass: Issuance and Renewal Deadlines

Passing both exams isn't the finish line - there are additional deadlines tied to licensure itself. Initial license issuance carries a $25 fee, and active contractors must maintain at least $500,000 of liability insurance to keep the license valid. Missing the insurance requirement can jeopardize your active status even after you've passed both exams.

From there, standard annual renewal costs $60 and requires 10 continuing-education hours completed before the renewal deadline. Existing licensees who qualify for the Compliant Contractor Program after a qualifying year have an alternative: complete just 8 hours annually, or opt into a 24-hour, three-year renewal cycle for $180 instead of paying every year. Planning your continuing-education hours around your renewal date - not scrambling right before it's due - keeps your license active without last-minute stress.
