NCCCO Overhead Crane Operator (CCO-OT) Written Practice Test

The official NCCCO Overhead Crane Operator written exam requires a minimum passing score of 80% (52 out of 65 questions correct). This high standard ensures that only operators with thorough knowledge of safety, load charts, and regulations are certified. Our practice test uses the same passing threshold to give you an accurate benchmark of your readiness.

The NCCCO certification is valid for five years from the date of successful completion of both the written and practical exams. To maintain certification, operators must complete a recertification process, which includes a written exam and a practical test, before the expiration date. Employers often require proof of current certification for continued employment.

The written exam covers eight core domains: Crane Components and Specifications, Emergency Procedures, Load Charts and Capacity, OSHA/ASME Standards, Pre-Operation Inspection, Rigging and Sling Angles, Signal Communications, and Site Assessment and Setup. Each domain is weighted, with load charts and rigging typically representing the largest portion of the test.

Yes, non-programmable calculators are permitted during the NCCCO written exam. You will need to perform calculations involving load weights, sling angle stress factors, and load chart capacity adjustments. Our practice test includes similar calculations to ensure you are comfortable with the math required.

While OSHA does not explicitly mandate NCCCO certification, it is the most widely accepted method for meeting the qualification requirements under 29 CFR 1910.179 (overhead cranes) and 29 CFR 1926.1400 (cranes in construction). Many employers and job sites require NCCCO certification as proof of competency, and it is often written into safety policies and insurance requirements.
