What it covers
The free 10-question check follows these domains, subject to the available practice questions.
Free check FAQ
How long is the free 10-question check?
The free check has 10 questions, is untimed and takes about 9 minutes. You see the answer and explanation after each question. It is a short study check, rather than a full-length exam simulation. Want exam pace? The 25-question practice test is also free. You can pause it, and it saves your place.
Is this an NCCCO Core exam practice test or a practical test?
This short check is organized around the Mobile Crane Operator Core written outline. The written specialties are Lattice Boom Cranes (LAT), Telescopic Boom Cranes, Swing Cab (TLL) and Telescopic Boom Cranes, Fixed Cab (TSS), per NCCCO's candidate handbook. They share one written outline, and our practice also covers it with simplified practice load charts for lattice and telescopic booms (not manufacturer charts), but there is no separate bank for each specialty. We do not cover Service Truck Cranes (STC). This is not a practical test or a complete specialty exam simulation, so prepare separately for your chosen specialty and practical assessment.
Is the 10-question check free?
Yes. You can start the check and see your score and weakest domain for free, with no signup or payment. Your score in each domain unlocks when you add your email.
Where does the practice content come from?
Every question is original and written to NCCCO's published outline. Treat the results as a starting point for study.
How is the check scored?
Practice items are grouped by the published outline's domains, subject to available questions. The check weights domain results using the configured published outline weights. This practice percentage helps set study priorities; it does not predict your exam score or certification outcome.
What do I see after finishing?
You get your score, your weakest domain and what the NCCCO written course holds for it. Add your email to see your score in each domain and get a free study plan.
How should I use the result to study?
Start with your weakest domain. The NCCCO written course has lessons, explained practice questions and timed exams on it. Want to test your pace first? Take the free 25-question practice test.
