What it is, who needs it, the three exams you have to pass, what it costs, and how long it lasts.

Reviewed November 2026 against the CCO candidate handbook and the CCO fee schedule.

NCCCO (CCO) certification is a nationally accredited crane operator credential that satisfies OSHA's operator certification rule. For a mobile crane you pass a 95-question Core written exam, a 28-question specialty exam for your crane type, and a hands-on practical, all within 12 months. It's valid for five years.

Who Needs It

OSHA 29 CFR 1926.1427 requires employers to make sure operators of covered construction cranes are certified by an accredited testing organization or licensed by a qualifying state or city, and then evaluated by the employer. CCO is the most common accredited route. Some states and cities, such as New York City, add their own license on top.

How to Get Certified

  1. 1

    Check eligibility

    You must be at least 18 and comply with the CCO Substance Abuse Policy and Code of Ethics.

    Choose your designation

    Mobile crane designations are Telescopic Boom Swing Cab (TSS), Telescopic Boom Fixed Cab (TLL), Lattice Boom Crawler (LBC), and Lattice Boom Truck (LBT). You can add more later.

    95 questions, 90 minutes, no calculator. Practice the Core exam free.

    A hands-on test on the crane type you are certifying for, scored by point deductions. It must be done within 12 months of your first passed exam.

Validity and Recertification

Certification lasts five years. Recertify in the final 12 months by passing the written exam again. With at least 1,000 hours of crane-related experience in the period, you skip the practical. Let it lapse and you retake both the written and practical exams.
