- OCCO is the Carpenters International Certification Council (CICC) credential for overhead crane operators, tied to the United Brotherhood of Carpenters.
- Certification requires passing both a closed-book written exam and a separate hands-on practical examination.
- The written exam (Form 090201, effective March 1, 2026) has 80 questions: 65 scored and 15 unscored.
- You get 3 hours, and the passing point is a scaled 500, not a raw percentage.
What the OCCO Credential Actually Is
The Overhead Crane Certified Operator (OCCO) credential is issued by the Carpenters International Certification Council (CICC), the certification arm associated with the United Brotherhood of Carpenters (UBC). It verifies that an operator can inspect, run and safely work around an overhead crane, and it does so through two separate assessments: a knowledge-based written examination and a hands-on practical examination.
That distinction matters because several unrelated crane credentials circulate in the industry, and candidates often confuse them. The OCCO described here is the CICC program. It is not a generic safety-training course, and it is not the same thing as an overhead-crane certification from another organization. If you are still orienting yourself, our explainers on what OCCO certification is and what OCCO stands for cover the basics, and the OCCO meaning page clears up the acronym.
Two Gates: Written Exam and Hands-On Practical
Many candidates prepare only for the part they can study at a desk. The OCCO does not work that way. Certification requires you to clear both gates:
| Component | Format | What It Tests |
|---|---|---|
| Written examination | Closed-book, computer-delivered through Pearson VUE; 3 hours | Knowledge of inspections, operations, components and safe practices |
| Practical examination | Hands-on, separate from the written test | Actual crane handling, including a one-point rollover hoist of the prop and moving a load through a diagonal course |
Passing one does not substitute for the other. A candidate who knows every component name but cannot move a load smoothly through a diagonal course has not completed the credential, and the reverse is equally true. For a broader view of how the two pieces fit together, see the OCCO study guide.
Inside the Written Examination: Form 090201
The current written exam is identified as Form 090201, effective March 1, 2026, replacing Form 090102. The key structural facts are:
- 80 total questions, made up of 65 scored items and 15 unscored experimental items.
- 3 hours to complete the test.
- Closed-book: no reference materials during the exam.
- Scaled passing point of 500.
What "scaled 500" means for you
A scaled score is not the same as a raw percentage. You cannot reverse-engineer the passing point into "I need to get X questions right," and no fixed correct-answer count has been published in the sources reviewed. What you can do is prepare for broad, reliable coverage rather than trying to game a cutoff. The OCCO passing score article digs further into how scaled scoring is generally interpreted.
The 15 unscored items
Fifteen of the 80 questions are experimental and do not affect your result, but they are not labeled on screen. Treat every question as if it counts. Spending extra time trying to "spot the unscored ones" is a waste of the 3 hours you have.
The Four Written-Exam Domains
The written exam is organized under four headings drawn from the issuer-indexed materials. The scored-item allocations are 17, 17, 19 and 12, respectively. Percentage weights have not been published in the sources reviewed, so none are stated here. For a deeper walk through each area, read the complete guide to the OCCO exam domains.
Domain 1: Pre-Job Inspections (17 scored items)
This domain covers what an operator must verify before a crane is put to work. Expect scenario-style questions about what to check, what to do when something looks wrong, and when a crane must be tagged out rather than used.
- Pre-shift and pre-lift inspection routines for the crane and its controls
- Recognizing defects in hoisting hardware and rigging attachments
- Deciding when an issue is reportable versus a reason to stop work
- Confirming the work area and travel path are ready
Domain 2: Crane Operations (17 scored items)
Operations questions test how you actually run the crane: smooth, controlled movement of loads, correct use of controls and sound judgment during a lift. This domain pairs naturally with the practical exam, so studying it does double duty.
- Controlled hoisting, traveling and positioning of loads
- Responding to signals and communicating during a lift
- Load handling principles, including keeping loads stable and under control
- Applying operating limits during normal and abnormal conditions
Domain 3: Crane Components (19 scored items, the largest allocation)
With 19 scored items, Crane Components is the single most heavily represented domain. Candidates who treat it as a vocabulary list tend to struggle; you need to understand what each component does, how it fails and why it matters to safe operation.
- Major structural and mechanical parts of an overhead crane
- Hoisting and travel mechanisms and the controls that govern them
- Hooks, wire rope and other load-bearing elements, including their wear and damage indicators
- Protective and limiting devices and their role in safe operation
Domain 4: General Safety & Operating Practices (12 scored items)
The smallest domain by item count still deserves attention, because safety questions are often the ones where a single wrong assumption leads to a wrong answer. Think of this as the judgment layer on top of the other three.
- Safe work practices around suspended loads and personnel
- Hazard awareness near the crane's path and work zone
- Operator responsibilities, including when to refuse an unsafe lift
- General rules that apply regardless of crane type or job site
Key Takeaway
Count the scored items: 17 + 17 + 19 + 12 equals 65. Crane Components has the biggest slice, but Pre-Job Inspections and Crane Operations together account for 34 items. Do not neglect any domain, since there is no published way to offset a weak area.
Eligibility Pathway: UBC, CRS and Medical Verification
The issuer-indexed materials point to three eligibility elements: UBC membership, the Certified Rigger and Signaler (CRS) prerequisite, and current medical verification. The UBC registration page adds that membership requires you to be 18 or older and eligible to work in the United States or Canada.
Two cautions apply. First, this is a summary drawn from indexed excerpts, not a complete independently verified eligibility checklist. Second, no specific training-hour thresholds have been confirmed, so do not assume or quote any. Before you invest time in exam prep, confirm your standing on each element directly with your Local Training Center. Our OCCO requirements article collects what is known about qualifying and where the gaps are.
Why the CRS prerequisite shapes your plan
Because Certified Rigger and Signaler is a prerequisite, the rigging and signaling knowledge you built there carries directly into Domains 1, 2 and 4. If your CRS is current and fresh, lean on it. If it has been a while since you worked with rigging inspection criteria or hand signals, expect to spend extra time reviewing before the written test.
Registration Mechanics Through the Local Training Center and Pearson VUE
Written exams are delivered by Pearson VUE and coordinated through CPS HR Consulting, but you do not simply book a seat on your own. The process runs through your training center:
- Submit a testing request through the Local Training Center before you try to schedule anything.
- Make sure your registration name matches your test-day ID exactly. A mismatch can derail an otherwise well-prepared attempt.
- Request accommodations early. CICC approval for accommodations must be obtained before registration.
- Watch the 48-hour rule. Cancellations or rescheduling must satisfy Pearson's 48-hour requirement.
- Know the no-show consequence. If you miss your appointment, you must submit a new testing request through the Local Training Center.
What to Know About the Practical Examination
The indexed practical description includes two named tasks: a one-point rollover hoist of the prop, and moving a load through a diagonal course. These are an overview only. A complete scoring rubric and a practical-test time limit were not retrieved, so this article does not state either one.
What you can do with that overview is prepare in a way that is consistent with it:
- Practice controlled, deliberate movement. A diagonal course rewards smooth, coordinated control over speed.
- Rehearse the rollover hoist conceptually. Understand what a one-point rollover involves and why load control matters during it.
- Connect the written domains to the hands-on work. What you learn in Crane Operations and Pre-Job Inspections should show up in how you handle the equipment.
- Ask your Local Training Center for the candidate-facing details rather than relying on a secondhand description of scoring.

Validity and Renewal
Per the official recertification-page index, CICC certifications are valid for four years from the last day of the month granted, and renewal involves written reexamination. The full renewal policy was not retrieved, so details such as eligibility for renewal, deadlines or any additional requirements should be confirmed with CICC. Plan on keeping your knowledge current rather than assuming you will only need it once.
Cost, Pass Rate and Pay: What Is Not Verified
A good article should tell you what it does not know. For the OCCO, the sources reviewed did not yield:
- A verified current fee schedule
- A complete historical pass-rate table
- A practical-test time limit
- Any documented certification pay premium
Rather than guess, treat these as questions to ask your Local Training Center or union training contact. If you want to see how we frame these topics as the evidence develops, our articles on OCCO certification cost, the OCCO pass rate and the OCCO salary guide take the same evidence-first approach, and the ROI analysis weighs the decision with those gaps in view. If you are exploring where the credential fits in the job market, see OCCO jobs.
Sequencing Your Preparation Around the Domains
Generic study advice is less useful here than a plan built from the exam's actual structure. The ordering below follows how the domains build on each other and where the points are concentrated. Adjust the timeline to your schedule and your CRS background.
Crane Components (19 items)
- Start with the largest allocation so you have the most time to absorb it
- Build a mental map of components, their functions and their failure signs
Pre-Job Inspections (17 items)
- Apply component knowledge to inspection decisions
- Practice deciding whether a finding means continue, report or stop
Crane Operations (17 items)
- Connect operating technique to the practical tasks you will face
- Review signals and load-control principles from your CRS background
General Safety & Operating Practices (12 items) plus full review
- Layer safety judgment over everything you have learned
- Take timed practice sets across all four domains and revisit weak areas
Because the exam is closed-book and runs 3 hours for 80 questions, you have time to read carefully, so build the habit of reading each scenario fully before choosing an answer. Our OCCO cheat sheet is a handy one-page review for the final days, and how hard the OCCO exam is sets realistic expectations about difficulty. When you are ready to test yourself, take a timed set on the OCCO practice test site and use the main practice question bank to find the domains where you are still guessing.
Key Takeaway
Prepare for the practical alongside the written exam, not after it. The Crane Operations and Pre-Job Inspections domains are where desk study and hands-on skill overlap most, so let each reinforce the other.
Frequently Asked Questions
The current written exam, Form 090201 (effective March 1, 2026), has 80 questions. Of those, 65 are scored and 15 are unscored experimental items. An older 100-question figure appears on some outdated listings and should be disregarded.
The written exam uses a scaled passing point of 500. It is not a raw percentage or a fixed number of correct answers, and no such conversion has been published in the sources reviewed.
No. The written examination is closed-book, and you have 3 hours to complete it. Certification also requires passing a separate hands-on practical examination.
Submit a testing request through your Local Training Center before scheduling. The written exam is delivered by Pearson VUE, your registration name must exactly match your test-day ID, and cancellations or reschedules must meet Pearson's 48-hour rule.
