Frequently Asked Questions


Are calculators permitted on certification exams?

Yes, but on certain exams only. Calculators are supplied for Mobile Crane Operator Specialty Exams (not Core), Digger Derrick Operator exams, Rigger Level II exams, Lift Director—Mobile Cranes, Lift Director—Tower Cranes, and Mobile Crane Inspector exams.

Why did NCCCO change its policy on calculator use for Mobile exams?

The change in policy is based on the results of a study commissioned by NCCCO. The study, The Effects of Calculator Use During NCCCO Testing, concluded that, while the use of calculators would not be appropriate for use on basic math questions such as those contained in CCO Core exams, their use would be supportable on load chart calculations used on CCO Specialty exams.

May I use my own calculator to test?

No. If policy allows calculator use for the exam you are taking, the calculator will be provided. You will not be permitted to use your own calculator or a calculator on a cell phone.

Am I required to use the calculator on the exam?

No. Although NCCCO allows the use of calculators on certain exams, candidates are not required to do so and may choose to test without the use of the calculator.

What type of calculator is supplied?

For paper/pencil testing a basic four-function calculator is provided by the Chief Examiner who administers the exam. For computer-based testing (CBT) an on-screen basic computer calculator is available.
