OCCO Pass Rate 2026: What the Data Shows

OCCO Pass Rate 2026: What the Data Shows

What Pass-Rate Data Actually Exists

Candidates searching for the Overhead Crane Certified Operator (OCCO) pass rate usually want one clean number. The honest answer is that a verified, complete historical pass-rate table for this credential, issued by the Carpenters International Certification Council (CICC), was not obtained during our most recent review. That means we will not hand you a percentage, because any figure we invented would be worse than no figure at all.

What we can do is lay out what the issuer's published structure tells you about how the exam is built, what it measures, and where candidates tend to lose attempts for reasons that have nothing to do with crane knowledge. That structural picture is more useful for planning than a headline percentage would be.

Why a Single Pass-Rate Number Is Misleading

Even if a pass-rate statistic existed, it would blend very different situations into one figure. Consider what a raw percentage would hide for this particular credential:

• Two separate exams. A written pass rate and a practical pass rate are different measurements. Certification needs both, so a number that describes only one of them overstates your odds of finishing.
• A recent form change. The written exam changed on March 1, 2026. Any pass rate computed on the older form describes a different test.
• A pre-screened population. Candidates must meet eligibility conditions before they ever sit the exam, which changes who is in the denominator.
• First attempts versus retakes. A pooled rate mixes people taking the test for the first time with people repeating it.

The 2026 Form Change and Why It Matters

The official indexed OCCO Exam Summary Report identifies written Form 090201, effective March 1, 2026, replacing Form 090102. The new form has 80 total questions: 65 scored and 15 unscored experimental items. Older directory and mirror pages that mention a 100-question exam are out of date and should be ignored.

Two practical consequences follow:

1. Old pass-rate claims are stale. Anything quoted from the earlier form does not describe the exam you will take.
2. You cannot tell which items count. The 15 experimental questions are mixed in with the scored ones. Treat every question as if it counts, because you will not know which ones do not.

Scaled Score 500: What It Means for Your Odds

The passing point is a scaled score of 500. It is not a raw percentage, and it is not a fixed count of correct answers. Scaled scoring exists so that different exam forms of slightly different difficulty can be compared fairly. The practical upshot is that you should not walk out of the test room trying to calculate a percentage from memory, and you should not trust any forum post that claims "you need exactly X right."

Two Gates: Written Exam and Hands-On Practical

Certification requires passing both a knowledge-based written examination and a separate hands-on practical examination. This is the single most important fact for interpreting any pass-rate discussion. A candidate can be strong on written content and still stall at the practical, and vice versa.

The indexed practical description includes a one-point rollover hoist of the prop and moving the load through a diagonal course. These are an overview only. We did not retrieve a complete scoring rubric or a practical-test timer, so we are not going to speculate about point deductions or time limits. If you are preparing for the practical, get the candidate-facing materials from your Local Training Center and the CICC.

Where the Scored Items Sit Across the Four Domains

The issuer's indexed written-examination headings give four domains, with scored-item allocations of 17, 17, 19, and 12. No percentage weights should be inferred from those counts, and we do not publish any. What the counts do show is where the exam spends its scored questions.

Crane Components has the largest published allocation, but no domain is negligible. Even the smallest, General Safety & Operating Practices, accounts for 12 scored items, which is a meaningful chunk when a single scaled cut score decides the outcome. For a deeper walk-through, see OCCO Exam Domains 2026: Complete Guide to All 4 Content Areas.

What each domain asks you to master

How Eligibility Filters the Candidate Pool

Issuer-indexed eligibility includes UBC membership, the Certified Rigger and Signaler (CRS) prerequisite, and current medical verification. The UBC registration page specifies that membership requires age 18 or older and eligibility to work in the United States or Canada.

This matters for pass-rate thinking because it means people arrive at the OCCO written exam having already cleared other steps. They have already earned CRS, they are already UBC members, and they have already verified medical fitness. That is a pre-screened group, so any pass rate you encounter describes a population that is not comparable to open-enrollment exams. We have not independently verified a complete eligibility checklist and we are not inferring any training-hour thresholds; confirm current requirements through the CICC. Our OCCO Requirements 2026: Eligibility, Prerequisites & How to Qualify article walks through what to confirm.

Logistics That Cost Candidates Attempts

Some of the most avoidable "failures" are administrative. Pearson VUE delivers the written examination, coordinated through CPS HR Consulting, and several rules can cost you an attempt before you open a single question:

• Submit the testing request first. Go through your Local Training Center before scheduling.
• Match your name exactly. The name on your registration must match your test-day ID exactly.
• Arrange accommodations early. Obtain CICC approval before registration, not after.
• Respect the 48-hour rule. Cancellation or rescheduling must satisfy Pearson's 48-hour window.
• A no-show resets the process. It requires a new testing request through the Local Training Center.

We also did not obtain a verified current fee schedule, so we are not quoting costs here. For what is and is not known about pricing, see OCCO Certification Cost 2026: Complete Pricing Breakdown.

A Domain-Ordered Preparation Plan

Rather than generic advice, here is a plan sequenced to the OCCO domains and to the fact that the exam is closed-book with a scaled cut score. The logic: start with the heaviest and most memorization-dependent domain, then build toward operation and safety judgment, and keep the practical in view throughout.

For a more detailed walk-through of methods, see our OCCO Study Guide 2026: How to Pass on Your First Attempt, and when you are ready to test yourself under realistic conditions, use the OCCO practice tests. A quick last-pass reference is available in the OCCO Cheat Sheet 2026.

What the Data Means for You

Since a verified pass rate is not available, the useful question is not "what percentage pass?" but "what would make me fail?" Based on the exam's published structure, the realistic risks are:

1. Underestimating the practical. Passing the written exam does not finish certification.
2. Neglecting a domain. With a single scaled cut score across 65 scored items, a gap in any one domain can drag you under 500.
3. Using outdated material. Prep built around the old 100-question form misses the current 80-question structure.
4. Administrative slips. Name mismatches, missed 48-hour windows, and skipped testing requests.

Address those four and you have dealt with most of what actually decides outcomes. Once certified, remember that CICC certifications are indexed as valid for four years from the last day of the month granted, with written reexamination described for renewal; confirm the full renewal policy with the CICC.
