If you operate a digger derrick—that truck-mounted machine that digs holes and sets utility poles—you need more than just experience behind the controls. You need proof that you can do the job safely and correctly.
That’s where certification comes in.
Federal regulations now require digger derrick operators working in construction to be certified. But beyond just checking a compliance box, certification shows employers you understand load charts, safety procedures, site setup, and the technical knowledge needed to prevent accidents.
For operators, certification opens doors to better jobs and higher pay. For employers, it means fewer accidents, lower insurance costs, and confidence that their crews can handle complex lifting operations safely.
The certification process involves passing both a written exam covering technical knowledge and a practical exam demonstrating real-world skills. It’s challenging, but with the right preparation, you can earn this credential and set yourself apart in the industry.

Your Path to NCCCO Digger Derrick Certification
Navigating heavy equipment operation requires not just skill, but also official recognition of that skill. For digger derrick operators, the gold standard is the National Commission for the Certification of Crane Operators (NCCCO) Digger derrick certification. This isn’t just a piece of paper; it’s a testament to an operator’s competence and commitment to safety, and it’s backed by some serious regulatory muscle.
Federal OSHA 29 CFR 1926 Subpart CC explicitly requires digger derrick operators involved with construction work to be certified. This means that if you’re working on a construction site in Indiana, holding a valid certification isn’t optional – it’s the law. Beyond federal mandates, the NCCCO program holds ANSI (American National Standards Institute) accreditation to ISO 17024, which means it meets rigorous international standards for personnel certification. This accreditation underscores its credibility and ensures that the certification process is fair, reliable, and legally defensible.
The NCCCO Digger Derrick Operator certification program wasn’t just pulled out of thin air. It was carefully developed with extensive input from key digger derrick manufacturers like Altec and Terex Utilities, along with experienced users and industry experts. This collaborative effort ensures that the certification accurately reflects the real-world demands and challenges of operating these complex machines.
Why is this important? Because operator certification has consistently been shown to improve safety and reduce accidents on job sites. By ensuring operators possess a verified baseline of knowledge and skills, we collectively contribute to a safer working environment. It’s about saving lives and preventing injuries, which is a goal we all share.

Eligibility Requirements for Digger Derrick Certification
Before you can even think about taking the exams, there are a few foundational eligibility requirements set by NCCCO. These are in place to ensure that all candidates are prepared for the responsibilities that come with operating heavy machinery. To be eligible for NCCCO Digger derrick certification, you must:
- Be at least 18 years of age.
- Comply with NCCCO’s Substance Abuse Policy. This policy outlines the importance of working in a drug-free environment and ensures operators are fit for duty.
- Comply with the NCCCO Code of Ethics. This emphasizes professionalism, integrity, and adherence to safety standards.
- Pass the Digger Derrick Operator written exam.
- Pass the Digger Derrick Operator practical (hands-on) exam.
It’s crucial to understand that these last two requirements, the written and practical exams, must both be successfully completed within a 12-month window from the time you pass the first exam. This ensures that the knowledge and skills tested remain current and fresh in your mind.
Decoding the NCCCO Written and Practical Exams
The NCCCO Digger derrick certification process involves two distinct parts, each designed to assess different aspects of an operator’s competency: a written examination and a practical examination.
The written exam is your chance to show you understand the theoretical knowledge behind safe digger derrick operation. It consists of 75 multiple-choice questions, and candidates are allowed 90 minutes to complete it. The exam covers five crucial content domains:
- Site and Setup: Understanding how to prepare a job site, assess ground conditions, and properly set up the digger derrick for operation, including outrigger placement and leveling. This includes recognizing and mitigating hazards like underground utilities or overhead power lines.
- Pre-Operation: Knowledge of daily inspections, maintenance checks, and understanding the various components of the digger derrick before beginning work.
- Operation: The actual mechanics of operating the machine, including auger operations (stowing/unstowing, digging holes), pole setting, pole pulling, and using personnel platforms. This also covers understanding the machine’s functions, limitations, instruments, and gauge readings.
- Technical Knowledge: General principles of digger derrick mechanics, safety devices, operational aids, and relevant regulations (OSHA, ASME).
- Load Charts: Critically important for safe lifting, this section tests your ability to read, interpret, and apply manufacturer’s load charts to determine gross and net capacity for various configurations.
The practical exam, on the other hand, is where you demonstrate your real-world skills. This hands-on assessment requires you to physically operate a digger derrick, performing a series of tasks that evaluate your proficiency and control. This includes demonstrating proper operating techniques, load control, and adherence to safety procedures. Our instructors at Train For The Crane know that there’s no substitute for hands-on experience, and we work hard to ensure our students are well-prepared for this crucial part of the certification process. For more detailed insights into what to expect, we encourage you to explore our page on the NCCCO Practical Exam.
12-month window we mentioned? It’s vital. You must pass both the written and practical exams within 12 months of passing the first one to achieve your full certification.
Certification Validity and Recertification
So, you’ve passed both exams, received your NCCCO Digger derrick certification card, and are ready to hit the ground running. Congratulations! Your certification is a valuable asset, and it’s valid for five years.
But what happens after five years? Just like a good mechanic keeps their tools sharp, a certified operator needs to keep their skills and knowledge current. This is where recertification comes in. The recertification process ensures that operators maintain their competence and stay up-to-date with any changes in industry standards, technology, or safety regulations.
To recertify, you must complete all renewal requirements during the 12 months prior to your certification’s expiration date. This typically involves passing a recertification written exam and, in some cases, demonstrating continued practical experience. NCCCO strives to make the recertification process as straightforward as possible, recognizing your ongoing commitment to safety and professionalism. It’s a way of proving that your skills haven’t faded and you’re still a top-notch operator.
