Crane certification exam prep for California job sites

California Online Crane School helps operators, riggers and signal persons get ready for nationally accredited certification exams on their own time. Study between lifts in a Bakersfield yard, on a ferry ride across the Bay or at the kitchen table in Redding, then walk into your written test knowing the material.

Our lessons are written around the work Californians actually do: port and refinery maintenance, high-rise and data center builds, seismic retrofits, utility hardening and the rebuilding that follows wildfire seasons.

EnrollPrep courses

Nine courses, one for each card you might need

Match the course to the machine you run or the role you fill on the lift. Every course page lists the exams involved, the topics the written tests lean on and what to expect when you get to the hands-on portion.

  • Mobile Crane

    Online study for the NCCCO mobile crane Core written exam and the LAT, TLL or TSS specialty that matches your machine, framed around how Cal/OSHA actually checks operators on California jobs.

  • Tower Crane

    Written exam preparation for the NCCCO tower crane certification, set against the extra layer of permits, notifications and certifier visits that Cal/OSHA applies to every tower crane in the state.

  • Articulating Crane

    Study for the NCCCO articulating boom crane written exams online, with the California size limits that decide whether a material delivery truck needs a certified operator at all.

  • Rigger I

    Learn to inspect gear, choose and tie the basic hitches and knots, and recognize rigging hazards, the core of the NCCCO Rigger Level I credential that many California employers use to document a qualified rigger.

  • Signalperson

    Study the standard hand signals, voice procedures and crane behavior behind the NCCCO Signalperson credential, and learn how a third-party certificate fits the Option 1 path in California's signal person rule.

  • Service Truck Crane

    Exam preparation for the NCCCO service truck crane designation, aimed at field mechanics, tire technicians and fleet crews who run a crane mounted on a service body rather than a full boom truck.

  • Digger Derrick

    Get ready for the NCCCO Digger Derrick Operator written exam and understand where California's utility-equipment exemption ends, so you can run pole-setting rigs with a portable credential behind you.

  • Rigger II

    Move from following a rigging plan to building one. This course prepares you for the NCCCO Rigger Level II exams: estimating weight, locating center of gravity, calculating sling tension and choosing gear for level and rotating lifts.

  • Recertification

    A self-paced refresher for operators whose NCCCO mobile crane card is nearing its five-year expiration, with a clear look at where California's Title 8 renewal wording differs from the national rule.

Built for a state where crane work is everywhere

Lifting in California ranges from container terminals in Long Beach and Oakland to tilt-up warehouses in the Inland Empire, from tower cranes over downtown San Diego to boom trucks setting trusses on rebuilt homes in Sonoma and Butte counties. The certification exams are the same national tests no matter where you sit them, but the conditions you bring back to the job are not.

That is why our material talks about Delta breezes, Santa Ana wind events, soft valley soils after a wet winter and the heat of a July pick in the Coachella Valley. Knowing the theory is one thing; knowing how it plays out on a California site is what keeps loads where they belong.

The California rule in brief

California workplaces fall under Cal/OSHA, which runs a federally approved State Plan. The state does not hand out its own crane operator license card. Instead, Title 8 has required since 2005 that anyone running a covered mobile or tower crane carry a certificate from an accredited body, and that certificate has to match the crane type being operated. Federal rules followed years later.

The specifics, including exemptions, signal person qualification and the annual crane inspections done by state-licensed certifiers, are laid out in our California certification requirements guide.

Where online study fits, and where it stops

Our job is the preparation: load charts, setup and stability, hand and voice signals, rigging hardware, wire rope inspection and the regulations behind them. You move through lessons and exam-style practice questions at whatever speed suits you.

The certificate itself is earned through a certifying body such as NCCCO. You pass their written exam, either at a test center, at a test event or through online proctoring, and you pass a practical exam on a real crane at a practical test site. No website can stand in for that hands-on test, and we never suggest otherwise.

For contractors with crews to certify

Companies can enroll several people at once, so a whole crew can study during slow weeks or rainy days instead of leaving the job for a classroom. Mention your headcount and the certifications you need on the form and an advisor will set up the enrollment.

Find your county or city

We have a page for every California county and for 68 cities and towns. Each one covers the local industries that keep cranes busy, the weather and ground conditions crews deal with, and the certifications that tend to come up there.

Which certificate does your crane call for?

Our California requirements guide explains Title 8 operator certification, the exemptions, signal person and rigger qualification, and when federal OSHA or MSHA takes over instead of Cal/OSHA.

Questions people ask

Is there a California crane operator license?

No state license card exists. What California requires is a certificate from an accredited certifying entity for the specific type of crane you run, plus training and qualification from your employer. Our requirements guide covers the details.

Can I finish the whole certification online?

Studying, yes. Written exams can sometimes be taken with an online proctor. The practical exam always happens in person, on a crane, at a practical test site. Our prep helps you get ready for both parts but does not replace the hands-on test.

I already hold a certificate. Is there anything here for me?

Yes. Certificates run for five years, and the recertification course helps you refresh before your written recert exam. California's rules on when the recert practical can be skipped differ from the national ones, so check the current Title 8 text and NCCCO requirements.

What devices do the courses work on?

Any phone, tablet or computer with a current web browser. Nothing to install, so a lesson can be opened from the truck cab as easily as from a desk.

How do I sign up?

Use the enrollment form on any page. Tell us the crane or role, the certification you are working toward and where in California you are based, and an enrollment advisor will get back to you with the next steps.
