What OCCO Certification Actually Is
OCCO is the Overhead Crane Certified Operator credential. It verifies that a crane operator can inspect, operate and safely manage an overhead crane, demonstrated through two separate assessments: a knowledge-based written examination and a hands-on practical examination. Passing only one does not earn the credential.
Because several credentials in the lifting and rigging world sound similar, it helps to be precise. This article covers the CICC credential, the one that pairs with the UBC (United Brotherhood of Carpenters) certification program. It is not a generic safety-training course, and it is not a certificate issued by a different certifying organization. If you are comparing options, make sure the program you are researching is the CICC OCCO before you invest preparation time. For a shorter definitional overview, see our page on what OCCO stands for and the companion explainer What Is OCCO?
Who Issues the Credential
The Carpenters International Certification Council (CICC) is the governing body for OCCO. CICC certifications are associated with the United Brotherhood of Carpenters, and the council publishes the program page, exam summary report, registration instructions and recertification information on its own site. Written examinations are delivered through Pearson VUE, coordinated with CPS HR Consulting.
The Two-Part Structure: Written Plus Hands-On
The structure of OCCO is what separates it from a classroom certificate. Candidates must pass:
- A written, knowledge-based examination delivered through Pearson VUE, closed-book, testing your understanding of inspections, operations, components and safety practice.
- A hands-on practical examination where you demonstrate actual crane handling.
The indexed description of the practical includes a one-point rollover hoist of the prop and moving a load through a diagonal course. That is an overview, not a complete scoring rubric, and no practical time limit has been confirmed publicly. The takeaway for preparation: written knowledge and physical load control are tested independently, so strength in one will not compensate for weakness in the other. Many candidates over-invest in memorizing facts and under-invest in smooth, deliberate control. Your Local Training Center is the best source for what the practical will look like in your region.
Written Exam Format and Scoring
| Feature | OCCO Written Examination |
|---|---|
| Current form | Form 090201, effective March 1, 2026 (replaces Form 090102) |
| Total questions | 80 |
| Scored items | 65 |
| Unscored experimental items | 15 |
| Time allowed | 3 hours |
| Passing point | Scaled score of 500 |
| Book policy | Closed-book |
| Delivery | Pearson VUE |
Two details deserve attention. First, older directory listings and mirror sites may still describe a 100-question exam. That figure is obsolete; the current form has 80 questions, of which only 65 count toward your result. Because the 15 experimental items are unscored but indistinguishable from scored ones, you must treat every question seriously.
Second, the passing point is a scaled 500, not a fixed percentage or a set number of correct answers. Do not search for a magic "you need X right" figure; scaled scoring exists so that different exam forms of varying difficulty remain comparable. Our dedicated breakdown, OCCO Passing Score 2026, explains how to think about this without guessing at conversions.
The Four Written-Exam Domains
The issuer's indexed headings define four content areas. The published scored-item allocations are 17, 17, 19 and 12 across the four domains in the order they are listed. Crane Components carries the largest allocation. No percentage weights are published in the sources reviewed here, so none are stated. For a deeper walkthrough, read OCCO Exam Domains 2026: Complete Guide to All 4 Content Areas.
Domain 1: Pre-Job Inspections
Before any lift, the operator is responsible for confirming the crane and its surroundings are fit for use. Expect scenario-style questions about what to check and when to stop.
- Pre-use and frequent inspection thinking: what gets verified before operation
- Recognizing conditions that require removing equipment from service
- Confirming the work area and load path before moving anything
Domain 2: Crane Operations
This domain covers how the crane is actually run: smooth control, load handling and working with signals and riggers.
- Controlled hoisting, travel and positioning of loads
- Working with a signaler and understanding signal communication
- Load-handling judgment, including how movement affects load stability
Domain 3: Crane Components
With the largest published item allocation, this is the domain where weak knowledge costs the most points. You need to know what the parts are, what they do and how they fail.
- Major structural and mechanical components of an overhead crane
- Hoisting and rigging-related hardware and their function
- Controls, limit devices and the role each plays in safe operation
Domain 4: General Safety & Operating Practices
The smallest allocation, but the content threads through everything else. Safe habits tested here are the same habits the practical examiner watches for.
- Safe operating practices and hazard awareness around suspended loads
- Responsibilities of the operator on the job site
- Appropriate responses when conditions change mid-lift
Key Takeaway
Do not read the smaller allocation of General Safety & Operating Practices as permission to skim it. Safety reasoning shows up inside inspection, operation and component questions too, so treat it as the lens for the whole exam.
Eligibility: What the Issuer Indexes
The issuer-indexed eligibility information includes three items: UBC membership, the Certified Rigger and Signaler (CRS) prerequisite and current medical verification. That prerequisite chain matters. You cannot treat OCCO as an entry-level starting point; rigging and signaling competence comes first.
The UBC registration page adds that membership involves being 18 or older and being eligible to work in the United States or Canada. Beyond that, do not assume additional requirements such as training-hour thresholds. Those have not been independently verified here, and inventing them would only mislead you. Our OCCO Requirements 2026 guide tracks what is and is not confirmed, and your Local Training Center can tell you what applies to your situation.
How Registration and Scheduling Work
The written exam is delivered by Pearson VUE, but you do not simply book a seat on your own. The process runs through the Local Training Center:
- Submit the testing request through your Local Training Center before scheduling.
- Match your name exactly. The name used in registration must exactly match your test-day identification, or you risk being turned away.
- Request accommodations early. If you need them, obtain CICC approval before registering.
- Mind the 48-hour rule. Cancellations and reschedules must satisfy Pearson's 48-hour requirement.
- Know the no-show consequence. A no-show requires a brand-new testing request through the Local Training Center.
How Long Certification Lasts
The indexed recertification information states that CICC certifications are valid for four years from the last day of the month in which they were granted, and describes written reexamination for renewal. The complete renewal policy was not retrieved, so confirm current renewal steps directly with CICC well before your expiration month rather than assuming details.
Cost, Pass Rate and Pay: What Is Not Publicly Confirmed
Candidates naturally ask about money and odds, and honesty here is more useful than guesses. No verified current fee schedule, practical time limit or complete historical pass-rate table was obtained from the sources reviewed. Likewise, there is no verified evidence of a specific certification pay premium to quote.
- Cost: confirm fees with your Local Training Center and CICC. Our OCCO Certification Cost 2026 page explains how to build a realistic budget without relying on invented figures.
- Pass rate: review OCCO Pass Rate 2026 to understand what data does and does not exist.
- Earnings and value: see the OCCO Salary Guide and Is the OCCO Certification Worth It? for a framework that identifies the gaps rather than papering over them.
- Difficulty: How Hard Is the OCCO Exam? discusses what actually makes the exam demanding.
Sequencing Your Preparation by Domain
You do not need an elaborate system. The one organizing principle worth using is to match study order to how the exam rewards you: put the most heavily allocated content first, then weave safety through everything. A simple four-week arrangement works for many candidates; adjust the pace to your schedule and your experience on the floor.
Crane Components first
- Learn the major parts and what each one does, since this domain has the biggest published allocation
- Write short plain-language descriptions of how each component fails
Pre-Job Inspections
- Practice thinking through what to check before a lift and what means "do not operate"
- Tie each inspection item back to the component it protects
Crane Operations
- Review signaling, load control and movement judgment
- Rehearse smooth control with a trainer, with the practical in mind
General Safety & Operating Practices, then full review
- Revisit safety reasoning across all four domains
- Take timed mixed practice sets and review every miss
For a fuller plan, see the OCCO Study Guide 2026, and keep the OCCO Cheat Sheet handy for last-minute review. When you are ready to test yourself, work through realistic questions on the OCCO practice test site.
