I've got about 6 years running mobile cranes and my employer is pushing me to get NCCCO certified before the end of the year. I understand the process requires both a written exam and a practical evaluation and I'm trying to figure out the right order. Some guys at my yard said written first, but I've also heard the practical can be scheduled independently.
My main concern with the written portion is load chart calculations and rigging math. I'm solid on the operational side from years of experience but those calculation questions don't come naturally from just running machines. I've been doing about an hour of practice daily for the past 3 weeks and I'm around 67% on timed practice sections, which feels low with about 7 weeks left before my planned written date.
I used a NCCCO Practice Test resource recently and noticed the load chart questions are really specific about lift radii and boom angles - more precise than what we typically eyeball in the field. Is there a trick to getting efficient at those calculations, or is it really just reps until table-reading becomes second nature?
Written first is the right call for most people because it expires after a set window, giving you a deadline to schedule the practical. I did written, passed at 79%, then had 6 months to arrange the practical site visit. That sequencing worked well - just don't let too much time pass between them.
For the practical, find out in advance what equipment the test site uses. If it's a machine type you're less familiar with, try to get some hours on it before your evaluation date. The practical examiners are strict on procedure and sequence, not just outcome.
67% at 7 weeks out is workable. The written exam is hard but your experience means you already have the conceptual understanding - it's mostly about learning how to translate what you know into the exam's question format. Most operators I know who studied consistently passed on the first attempt.
The load chart math really does just come down to reps. I did 15-20 load chart problems per day for 4 weeks before my exam and went from 64% to 88% on those question types specifically. Setting up a systematic approach - locate boom angle first, then radius, then rated capacity - makes you a lot faster under timed conditions.
Just wanted to drop a quick update since I've been following this thread. Took a practice test last night for the CCO Core and scored a 78, which honestly surprised me because I wasn't expecting to do that well this early in my studying. I've got about three weeks of prep left and I'm planning to sit the written at the end of July.
Going written first made sense to me since it's the same knowledge base you'll be pulling from during the practical anyway. If you know the load charts and safety regs cold, the practical just becomes about proving you can apply it. Good luck to whoever's still deciding, but from what I've heard from guys who've done it, written first is the way to go.
Written first, no question. I went through this whole process about two years ago and the written exam actually helped me understand the load chart concepts well enough to perform better during the practical. What I'd suggest is don't just drill answer keys — figure out why the wrong choices are wrong. When I was studying I'd actually look up what situation would make the wrong answer seem tempting, and that clicked everything into place way faster. Same thing helped me when I was messing around with a forklift practice test pdf to get comfortable with the question format before moving to crane-specific material.
With 6 years on mobile cranes you're probably underestimating how much you already know, but the written will expose gaps in your knowledge of hand signals, ASME standards, and rated capacity stuff that you just do by feel on the job. Pass the written, internalize the reasoning behind it, and the practical almost becomes a formality at that point.
