Frequently Asked Questions
Does Crane Prep replace practical training?
No. Digital practice supports concept review but does not reproduce crane controls, the physical practical test course or employer evaluation. Check the current CCO candidate handbook for the credential and specialty you are pursuing, and use qualified hands-on training for practical preparation.
How many questions are on the NCCCO crane exam?
The referenced CCO Mobile Crane Operator handbook lists 95 questions in 90 minutes for Core and 28 questions in 60 minutes for each separate mobile specialty. Check the current handbook and candidate records for your exam. Criterion-referenced; CCO does not publish a percentage cut score.
What topics are on the NCCCO core exam?
The referenced CCO Core blueprint separates Site, Operations, Technical Knowledge and Load Charts. Use its current content outline to plan supplemental review; the app's topic groups are not a certification blueprint or proof that every official requirement has been covered.
