RAI Passing Score 2026: Exactly What You Need to Pass

The Number: 80% or Higher

If you are searching for the RAI passing score, here is the short answer for the RETA Authorized Instructor credential: you need at least 80% correct on the written examination. RETA's RAI certification page states the 80% requirement, and the 2026 RAI Exam Information Handbook describes a passing score of 80 or higher. Both point to the same threshold, so you can plan around it with confidence.

On an 85-question exam, that threshold has a practical meaning. Eighty percent of 85 is 68, so a candidate needs 68 correct answers to meet the requirement, which leaves room for 17 misses. That arithmetic is simple math applied to the published figures, and it is worth internalizing: you are not aiming for perfection, but you are not aiming for a bare-minimum pass either. A fixed 80% bar means you should walk in prepared to be comfortably above it on every major area of instructional practice.

This article covers the written exam's score requirement specifically. The RAI pathway also includes instructional-evidence review and the RETA Train the Trainer program, and those elements are evaluated separately. The 80% figure applies to the written examination. For a bigger-picture view of the full path, see our guide to RAI requirements, eligibility, and prerequisites.

What the Score Is Actually Measuring

The RETA Authorized Instructor credential is about teaching industrial refrigeration professionals, not about operating a plant. That distinction shapes what an 80% score represents. The RAI is designed for people who already have deep industrial refrigeration experience and now need to demonstrate that they can instruct others effectively and responsibly. So the score reflects readiness to deliver and manage training, not just technical recall.

RETA's handbook lists the instructional competencies it expects an RAI to demonstrate. We treat these as unweighted preparation topics rather than a published written-exam blueprint, because the handbook does not assign percentages to them. The takeaway for passing: you cannot afford to ignore any area, because there is no official weighting that lets you safely skip one. Our companion piece on the RAI exam domains and all seven content areas walks through each competency in detail.

Format, Timing, and Testing Rules

Understanding the format helps you convert the 80% requirement into a realistic pace and strategy. Here is what RETA publishes for the written examination:

Pacing the three hours

Three hours for 85 questions works out to roughly two minutes per question. That is generous for multiple-choice items, which means time pressure is rarely the main risk. The more common trap is overthinking scenario-style questions about instructional practice, where several answers can sound reasonable. Read each item carefully, choose the answer that reflects sound adult-learning and training practice, and flag anything uncertain for a second pass if the testing interface allows it.

What you can and cannot bring

• Prohibited: outside books, copies of study guides, and phones.
• Provided: issuer-supplied onscreen reference PDFs are available during the exam.
• Calculator: bring a nonprinting, nonprogrammable calculator with its memory cleared.
• Security caution: using CTRL+F inside the reference material may trigger a security logout, so do not rely on keyword-searching the onscreen PDFs.

The Seven Competencies Behind the Score

The 2026 handbook's page on RAI Instructional Evidence and Evaluations lists seven instructional competencies. We reproduce them as study topics. They are preparation areas, not an official seven-domain written-exam blueprint, and RETA does not publish a weighting for them.

Notice how these map to the lifecycle of a training program, from assessing a need through documenting results. That lifecycle is the best mental frame for the exam: when a question describes a training problem, ask yourself which stage of the cycle it belongs to and what sound practice looks like at that stage.

Passing Score vs. Pass Rate

Candidates frequently confuse these two ideas. The passing score is the threshold you must reach: 80%. The pass rate is the share of candidates who succeed. They are completely different things, and a high or low requirement says nothing by itself about how many people pass.

As of our October 2026 research, no current issuer-published pass rate has been verified for the RAI. Any figure you see elsewhere without a clear RETA source should be treated with skepticism. We discuss what is and is not known in our article on the RAI pass rate and what the data shows, and if you want a candid read on difficulty, see how hard the RAI exam is.

One useful way to think about it: the candidate pool is self-selecting. People reach the exam only after meeting substantial experience and documentation requirements, so the 80% bar is applied to a group that has already cleared significant hurdles. That context is a reason to prepare thoroughly rather than a reason to assume the bar is low.

The Gates Before You Ever Sit for the Exam

Hitting 80% is only one gate. The RAI requires you to qualify before testing, and understanding those prerequisites prevents wasted effort. Per RETA's published information, the path includes:

• RETA membership in good standing
• Six years of industrial refrigeration experience, supported by Verification of Experience
• Documented instructor experience and a resume
• Four professional references, with no more than one from the same company or source
• Curriculum and sample-lesson evidence
• Completion of the RETA Train the Trainer program
• Compliance with the RETA Code of Conduct
• Certification Committee approval

Because the written exam sits at the end of this process, the instructional-evidence portion effectively rehearses several of the same competencies the exam probes: curriculum design, lesson planning, and measurement. Building a strong evidence package is therefore also a form of exam preparation. For a full walkthrough, read our guide on how to qualify for the RAI.

Retake Limits and Fee Facts

How often you can test

RETA's Section 500 certification policy (Revision 14, approved March 21, 2026, and affirmed by the Board April 17, 2026) limits RAI testing to once every four months and no more than twice in twelve months. This is the single most important reason to treat your first attempt seriously. A miss does not just cost money; it can push your next attempt months out and eat into your annual allowance.

What it costs

• Initial application and exam fee: USD 950.
• Re-examination fee: the retrieved 2026 handbook states USD 735. A previously reviewed RETA application page was recorded as USD 685, but that page was not accessible on our most recent check, so we cannot confirm which figure applies to you.

Given that conflict, confirm the current retake charge directly with RETA staff before you schedule. We break down the full pricing picture in our RAI certification cost guide.

A Score-Targeting Plan Built Around RAI Content

RETA does not offer an RAI-specific study guide or practice test. Its handbook instead directs instructors toward study resources associated with the CARO, CIRO, CRST, and CRES certifications, without making those exams' domains the RAI syllabus. That means you must assemble your own preparation around the seven instructional competencies. Here is one way to sequence it so each week serves the 80% goal:

The logic of this order follows the training lifecycle, so each week builds on the last. Record keeping comes last because it depends on understanding what you are recording. Use the final week to simulate the real conditions: a full-length timed session with no notes. For a broader plan, see our RAI study guide on passing the first time, and when you want realistic multiple-choice repetition, use the RAI practice tests.

Building a personal 80% buffer

Since 68 of 85 correct is the line, track your practice results by competency rather than only as an overall percentage. An overall 82% can hide a competency where you are guessing. Aim to be at or above the threshold in every area so that no single weak spot threatens the total. A quick reference of core facts can help the night before; our RAI cheat sheet condenses the must-know points.

After You Pass: Keeping the Credential

Earning the credential is not the end of the score story, because RETA ties ongoing certification to continued performance as an instructor. Renewal occurs every three years and requires:

• Continued RETA membership
• 24 relevant professional development hours (PDHs)
• 25 student training evaluations submitted directly by students
• Required documentation and a USD 735 renewal fee

There is also an instructional quality benchmark: an average training-evaluation score below 4.0 requires repeating Train the Trainer. In other words, the credential's quality bar continues well past exam day. If you are weighing whether the effort pays off, our analyses of whether the RAI is worth it and the RAI salary picture can help you decide.

One related policy to know: taking the CARO, CIRO, CRST, or CRES exams triggers a stated two-year restriction on teaching candidates for the exam taken. This is not a ban on all instructor activity, but it is worth understanding if you plan to pursue those credentials yourself.
