Questions
When do I get access?
Straight away. Checkout takes you to your course, and the receipt email has the same link.
How do I get back into my course?
Use the link in your receipt email. If you can't find it, enter your email on the course page and we resend it to the address on your order.
Is 524 questions enough?
Each one comes with a worked explanation and its reference. You also get 24 end-of-module checks and 2 worked calculations. Today's 10 and your missed set bring your misses back on later days, so you work the bank instead of reading it once.
Can I get a refund?
Eligibility depends on your plan, when you request a refund and your paid use. See the refund terms for the conditions and exceptions.
What if I need a retest?
Keep studying in the same course. Your access has no end date, so your retake prep is already paid for, and your practice history, missed questions and readiness by domain are still there. The 7-day pass is the exception: it ends after 7 days.
How long do I keep access?
Lifetime access: your access has no end date. Updates are included, so if NCCCO moves this exam to a newer code edition while you have access, your course moves with it. The 7-day pass is the exception. 7-day pass: access ends 7 days after payment, to the minute. It does not renew and is not a subscription. A timed practice exam started before then can still be finished.
More questions (10)
Which editions does the course use?
The questions are built on ASME B30.5 and OSHA 29 CFR 1926 Subpart CC, from the references NCCCO lists.
If I buy the 7-day pass now, is its price taken off a bigger plan later?
No. Each plan is a separate purchase at its listed price, and the $19 paid for the 7-day pass is not credited toward another plan. With more than a week before your exam, a full plan is the better buy.
Are the questions copied from the exam?
No. Every question is original and written to NCCCO's published content outline. Exam content is confidential and we never use it. We are not affiliated with or endorsed by NCCCO.
How are the questions written?
In our own words, to NCCCO's current published outline. See how many questions cover each domain.
What do the NCCCO written exams cost, and how are they taken?
The Core written exam is $140 and each Specialty written exam is $80. You can take written exams online with a remote proctor, at a test center, or at an event online.
How does recertification work?
Certification lasts 5 years. You complete recertification in the 12 months before it expires by passing the written exam or exams again. If you can attest to at least 1,000 hours of crane-related work during your certification, you do not need to retake the practical exam. There is no grace period after expiry, and anything that needs a practical must be done before then.
Which specialties does the course cover?
The Core exam and the Specialty written outline that LAT, TLL and TSS share, with original practice charts for lattice and telescopic cranes. There is no separate question set per specialty.
Can my employer pay?
Yes. Pay at checkout and we email a receipt you can expense, or download a reimbursement request to send your manager.
Is Hook AI?
Yes. Hook is an AI study assistant, not a person or an instructor. Check important details against your lessons and references.
Can you promise I will pass?
No, and nobody honest can. We promise everything listed in your plan, and a fix within 2 business days for any wrong answer key.
