Drill Rig 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 Drill Rig Operator Written Examinations required for recertification are identical to the written exams required for initial certification.

Candidates who can attest to at least 1,000 hours of related experience during their period of certification do not need to take the practical exam to recertify. Related experience is defined as: operating, maintaining, inspecting, or training on drill rigs. Candidates who do 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’s expiration date.

Candidates whose certification has lapsed must take both the written and practical examinations to be certified again.
