Written exam fees, the four-week retake wait and the 12-month window
✓ Checked 17 Oct 2026 against NCCCO's exam fee schedule, exam retake policy, Mobile Crane Operator certification overview and candidate handbook.
For mobile crane operator certification, budget for the Core written exam, the written specialty for your crane type and the matching practical exam. Written preparation is only part of the route. Timing matters too: a failed written exam can mean a waiting period, while passing your first exam starts the certification completion window.
This guide covers the mobile crane Core and specialty route. Return to the Boom Angle overview for the site's scope, or read the Core written exam guide for study priorities.
What the written exams cost
The NCCCO fee schedule lists the following charges in US dollars, effective 1 January 2024 and still displayed when checked:
- ✓ Mobile Crane Operator Core written exam: $140.
- ✓ Each written specialty: $80 for Lattice Boom, Telescopic Boom Fixed Cab or Telescopic Boom Swing Cab.
- ✓ Each corresponding practical exam: $70 in CCO fees.
Calculated from that schedule, Core plus a single written specialty totals $220. Adding the corresponding practical brings the listed CCO exam fees to $290. This is fee arithmetic, not an all-inclusive training or testing-site quote.
The written fee column covers Event Online Testing (EOT), Online Proctored Testing (OPT) and Test Center Testing (TCT). Choose the delivery option that fits your location and equipment before arranging the rest of your schedule.
Keep preparation, travel and any testing-site or crane-use charges separate from the published CCO fees. Ask for an itemized quote when comparing a school package with independently arranged exams. Check which written specialties and practical tests the quote includes, what equipment is provided and what happens if you need another attempt. Do not assume a package price is the exam body's registration charge.
The four-week written retake rule
✓ NCCCO's exam retake policy requires candidates who fail a written exam to wait four weeks before retaking that same exam. It applies to certification and recertification candidates.
There is an exception: if an alternate form is available, a candidate may retest within that period. An alternate form assesses equivalent content and difficulty using different items. NCCCO says it determines whether an alternate form is needed when processing the application; without an available alternate, scheduling remains unavailable until the waiting period has passed.
Do not build a deadline around an assumed immediate retake. Check availability for your specific exam through the official process. The policy expressly says this waiting rule does not affect practical retakes. It does not establish a guaranteed practical appointment date, so confirm practical availability separately.
When the 12-month window starts
✓ The candidate handbook gives candidates 12 months after passing their first exam to pass the corresponding exams for the same designation. The certification overview confirms that written and practical exams can be taken in either order.
Passing the practical first therefore starts the clock just as a written pass does. Track the Core, specialty and practical results together. The overview explains that passes within a qualifying period can count together; an older pass outside that period may need to be retaken. A later pass does not make every earlier result valid indefinitely.
Leave room for a written retake and for practical scheduling when setting your target completion date. Record the date and designation beside each result instead of keeping only a general note that you have “passed the written.”
Plan before booking
Confirm the crane designation you need, then map the required exams and available appointments. Read the certification requirements guide to distinguish the credential from employer evaluation and other job requirements.
Use the written exam diagnostic to identify study priorities before choosing a written test date. Compare the result with the published outline, then work on the topics you cannot yet explain or calculate consistently. A practice score helps organize preparation; it does not establish eligibility or predict the official result.
