How we research and update this site

Sources we rely on

For California rules we go to the regulation itself: Title 8 of the California Code of Regulations as published on dir.ca.gov, along with Cal/OSHA and Crane Unit material and Occupational Safety and Health Standards Board records for pending rule changes. Federal requirements come from osha.gov and the eCFR text of 29 CFR 1926 Subpart CC. Certification details such as exam structure, recertification and fees come from NCCCO's own published pages and handbooks.

Pay and employment figures come from the U.S. Bureau of Labor Statistics. Local details on our county and city pages, such as ports, projects, highways, terrain and weather, come from public agencies, project owners and established news outlets.

• Every page ends with a "Sources we checked" panel listing the pages we actually used.
• Numbers that change over time, like wages or exam fees, are tied to their publisher and the year they describe.
• If a detail can't be confirmed from a reliable source, it stays off the page.

How pages are checked and dated

The "Last updated" date under each heading is the date a person last reviewed that page, not the date a template or design changed. We revisit pages when Title 8 or federal crane rules are amended, when the Standards Board acts on a crane-related rulemaking, when a certifying body changes its policies, or when a local project we mention moves to a new stage. Where a rule change is in progress, we say so and point you to the official text instead of guessing how it will end.

What we don't publish

We do not make up reviews, testimonials, statistics, students or staff. We do not promise that you will pass an exam, get hired, receive a license or save a certain amount of money, and we never suggest that online study can stand in for the hands-on practical exam. Our practice questions are written by our own team; we do not reproduce questions from NCCCO or any other certifier or prep provider. Photos are credited stock images and are not presented as our students or specific California job sites.

We are independent of NCCCO, Cal/OSHA, the Department of Industrial Relations and federal OSHA, and none of them has endorsed this site.
