NCCCO Mobile Crane Operator Certification Overview

The National Commission for the Certification of Crane Operators (NCCCO)is nationally recognized as the "Gold Standard", and has unrivaled credibility as the leader in the professional credentialing of Crane Operators, Riggers, and Signalpersons. Many states require certification and only acknowledge licenses obtained through NCCCO by an accredited provider.You can find Craneology in the NCCCO's list of accredited Practical Examiners for:
LB, TLL, TSS, STC, RIG-I, RIG-II, and SGP.

Mobile Crane Operator Recertification

The Core and Specialty Written Exams for recertification are required, and are the same as those for initial certification.
If you can prove at least 1,000 hours of crane-related experience, a Practical Exam for recertification is not required.
If a Practical Exam is needed, it must be completed BEFORE your certification expires, or both the Written AND Practical Exams will be required to certify again.
