Official NCCCO exam resources

The most reliable NCCCO exam resources come straight from the organizations that write the tests and the rules. Start with these:

  • NCCCO's website (nccco.org (opens in a new tab)) publishes candidate handbooks, exam outlines, recertification requirements and policies for every certification. Read the handbook for each exam you plan to take; it lists the content areas the test covers.
  • Certification verification at verifycco.org (opens in a new tab) lets employers, safety officers and operators confirm whether a CCO certification is current. It is a quick check before someone climbs into the seat.
  • State and city licensing information is also maintained on NCCCO's site. Several states and cities have crane operator requirements in addition to federal OSHA, so confirm current rules with the state agency before you take work in a new area.

Federal rules and career data

OSHA cranes and derricks standard

Construction crane work in the U.S. falls under OSHA 29 CFR 1926 Subpart CC. Section 1926.1427 covers operator certification, 1926.1428 covers signalperson qualification, and 1926.1408 covers power line safety. You can read the regulation text on osha.gov (opens in a new tab). Knowing where these rules live helps on exam day and on the job. Our blog post on OSHA compliance for crane operators summarizes the main requirements in plain language.

Pay and job outlook

For reliable earnings and employment figures, use the U.S. Bureau of Labor Statistics Occupational Employment and Wage Statistics for crane and tower operators (53-7021) (opens in a new tab). It breaks data down by state, metro area and industry, which is far more useful than a single national figure.

How to prepare for your exams

Candidates who do well usually follow a similar routine:

  1. Learn load charts until they feel routine. Load chart questions are a major part of the mobile crane written exams. Work practice problems with the actual charts, not just summaries.
  2. Study the regulations by topic. Group your reading around setup, power lines, signals, rigging and inspections rather than reading the standard front to back.
  3. Get real seat time before the practical. Practical exams test smooth, controlled operation through a set course. If you need more time on the controls, hourly TSS and TLL practice time is available at our Seffner yard.
  4. Rest before test day. Arrive early with your ID, hard hat and hard-toe boots.
  5. Review what you missed. If a written exam doesn't go your way, NCCCO Testing Services (727-449-8525) is the place to ask about your results. Training providers only receive pass or fail information.

Study in short, regular sessions instead of cramming the night before. Many students find it helps to explain a load chart problem out loud, as if teaching it to someone else; if you can't explain a step, that is the area to review. Bring your questions to class, where an instructor can walk through them with you on the actual equipment.

Frequently Asked Questions

How can I check whether an operator's CCO certification is valid?

Use NCCCO's verification site, verifycco.org. You can confirm a certification's status in a few minutes.

Where do I find the content outline for an NCCCO exam?

NCCCO publishes candidate handbooks for each certification on nccco.org. They list the content areas and reference materials for each written and practical exam.

Can I practice on a crane before my practical exam?

Yes. The Crane School sells hourly practice time on telescopic and lattice boom cranes at our Seffner facility. Call the office to reserve a slot.
