Exam Format
Before You Begin
NCCCO lists the Mobile Crane Core Examination as 95 multiple-choice questions in 90 minutes. This unofficial mock matches that length and time. NCCCO does not publish a fixed pass percentage on its program pages, so 70% here is our practice target. Questions come from OSHA 29 CFR 1926 Subpart CC and NCCCO pages, not the NCCCO item bank, ASME B30.5 or manufacturer load charts. Source: NCCCO Mobile Crane Operator Written Exam.
- The timer starts when you begin and the exam submits itself when time runs out.
- Move freely with Previous, Next or the numbered navigator, and flag any question to come back to.
- No feedback is shown until you submit. Unanswered questions count as wrong.
- Nothing is sent anywhere; the exam runs entirely in your browser.

What the NCCCO Mobile Crane Core Mock Exam Covers
Each attempt draws 95 questions at random from a pool of 177. The pool covers these topics. Your score report breaks your result down the same way, so you can see which areas need more study.
| Topic | Questions in Pool | Share |
|---|---|---|
| Site, Ground and Power Lines | 46 | 26% |
| Operations, Signals and Personnel Lifts | 56 | 32% |
| Inspections, Wire Rope and Devices | 59 | 33% |
| CCO Program Rules (NCCCO) | 16 | 9% |
About 63% of the pool is recall and core-concept questions. The other 37% are harder applied questions, such as scenarios, calculations or details that are easy to confuse.
Editor's Note on the NCCCO Mobile Crane Core Exam
Load Charts make up about 26% of the Core, and NCCCO expects basic math there without a calculator. A study it commissioned found calculators were not appropriate for Core basic-math questions, though they are supportable on Specialty load chart work. So drill percentage and deduction arithmetic by hand, not on your phone. Source: NCCCO Calculator FAQ.
NCCCO Mobile Crane Core Mock Exam Pacing Plan
You have 90 minutes for 95 questions, which is about 57 seconds per question. Use these checkpoints to stay on pace:
| Checkpoint | Be at or past question | Elapsed time |
|---|---|---|
| First quarter | 24 | 23 min |
| Halfway | 48 | 45 min |
| Three quarters | 71 | 68 min |
If you are behind, flag any question that is taking too long and move on. Leave a few minutes at the end to go back to your flagged questions. Unanswered questions count as wrong, so give an answer to every question before time runs out.
What Score Do You Need?
To pass, you need 67 of 95 correct (70%), so you can miss up to 28 questions. The official pass mark is not published in a form we can verify, so treat this as a practice target. We suggest scoring 10 points above the pass mark on two attempts in a row before you book the real exam, because the pool here is smaller than the official bank.

How to Use Your Score Report
- Sort by topic. Start your next study session with any topic where you scored below 70%.
- Read the source. Each answer cites a section or quotes its source text. Read the surrounding passage, not just the answer line.
- Drill, then retest. Use the adaptive practice test on your weak topics. It gives you more of the kinds of questions you miss. Then take this mock again for a new random set.
- Return to the guide. The NCCCO Mobile Crane Core guide covers exam fees, scheduling, retake rules and what to bring on test day.
