Why a Drill Rig Has Its Own CCO Credential
NCCCO developed the drill rig program with the foundation drilling industry so that operators of rotary drill rigs — the machines that turn Kelly bars, augers and core barrels to build drilled shafts — could earn a credential tailored to their equipment instead of a generic crane card.
Whether OSHA's crane operator certification rule applies depends on how the rig is used. When it's hoisting and placing loads such as casing or reinforcing cages, it's doing crane work, and owners frequently treat it that way. Some general contractors and public owners also write certified drill rig operators into their project specifications. Confirm coverage for your specific equipment with your safety team and OSHA.
Read our guide to becoming a certified drill rig operator for the career path that typically leads to this credential.

Routine inspection, troubleshooting and fire prevention
Emergency procedures and demobilization
How the Testing Is Structured
| Stage | Requirement |
|---|---|
| Eligibility | Be 18 or older; comply with CCO substance abuse policy and code of ethics |
| Written exam | Knowledge of equipment, ground, operations, hoisting and safety |
| Practical exam | Demonstrated operation of a drill rig under an examiner |
| Time limit to finish | All components within 12 months of the first one passed |
| Card validity | Five years |
How Our Drill Rig Course Supports the Written Exam
Drill rig operators usually know their own machine extremely well and the exam’s broader content less well. The course is designed to close that gap: soils you may not drill in, tooling you may not use, and the hoisting math that matters when the rig handles casing and reinforcing cages.
Each module ends with questions so you can tell what you have mastered and what needs another pass. The capstone unit pulls everything together with scenario questions and exam strategy, so you walk into the test center or online session with a plan.
Finishing earns a certificate of completion for your training records. NCCCO issues the actual credential once you have passed its written and practical exams.
From Driller's Helper to Certified Operator
Learn the rig on the job
Practical tasks assume you can already control the rotary, crowd and hoist functions smoothly.
Study the written domains
Use the online course to fill gaps in soils, hoisting math and regulations.
Take timed practice tests
Our practice tests build exam stamina and pacing.
Schedule both exams
Book the written with NCCCO and arrange a practical where a suitable rig is available.
Complete your employer evaluation
Your company must still confirm you can run its rigs safely before you work independently.
