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 CCO Mobile Crane Operator Recertification Written Examinations consist of a Core Examination in crane operation and up to four Specialty Examinations.

  • The Core Recertification Examination has 40 multiple-choice questions with a time limit of 45 minutes.
  • Each Specialty Recertification Examination consists of 10 multiple-choice questions with a time limit of 30 minutes. Four of the questions in each Specialty Exam are load chart questions.

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 regular Written and Practical Examinations again to be certified again 

All candidates are allowed two attempts to pass their Recertification Core and Specialty Exams before their certification expires. Candidates who are unsuccessful after two attempts must take and pass the regular Core and Specialty Exams.
