Mobile Crane Operator


CCO certification is valid for five years. Recertification candidates must complete all recertification requirements during the 12 months prior to their certification’s expiration date.

The Mobile Crane Operator Written Examinations consist of a Core Examination in crane operation and up to four Specialty Examinations. The written exams required for recertification are identical to the exams required for initial certification.

Candidates who can attest to at least 1,000 hours crane-related experience during their period of certification do not need to take the practical exam to recertify. Crane-related experience is defined as: operating, maintaining, inspecting, or training on cranes.

Recertification candidates who need to take the practical exam for any reason, however, must do so before their certification expires. There is no grace period after their certification expires. Candidates whose certification has lapsed must take both the written and practical examinations again to be certified again.
