Two riggers can arrive at the same project with opposite problems: One may have years of experience but be turned away because the contract requires a CCO Rigger Level II card, issued through the National Commission for the Certification of Crane Operators. The other may carry the card yet have limited experience applying that knowledge beyond an exam setting.
That is why “Are your riggers certified?” is an incomplete prequalification question. Certification and training are not competing standards. A credential verifies performance against a national standard. Training builds the judgment to apply that knowledge when the load, equipment, environment or plan changes.
General contractors, facility teams and project owners need both. In the end, a card can satisfy a contract, but it cannot make a lift safe all by itself.
OSHA requires qualification, not one universal card
The federal baseline is more specific – and less absolute – than many project teams assume. OSHA’s crane standard, 29 CFR 1926 Subpart CC requires a qualified rigger during crane assembly and disassembly and when workers in a load’s fall zone are hooking, unhooking or guiding the load, or making its initial connection to a structure or component.
OSHA does not require every rigger to hold a certification from an accredited organization or undergo a third-party assessment. The employer must determine whether the person is qualified for the work being performed. That determination can rest on a recognized degree or certificate, or on knowledge, training and experience demonstrated through the ability to solve problems related to the work.
OSHA qualification is task-specific, which means someone qualified to rig one kind of load is not automatically qualified for every lift – a credential is evidence of qualification rather than a universal substitute for it.
Signal persons operate under a different rule. They must be evaluated on their knowledge and practical application of signals, understanding of crane operations and ability to recognize relevant hazards. Crane operators have separate training, certification and employer-evaluation requirements. Credentials for these roles are not interchangeable.
Why the card still controls site access
If federal rules do not mandate one universal rigger certification, one might ask why a crew with decades of experience can still be denied access to a project?
Many owners, general contractors and insurers set a higher contractual threshold. Requiring a CCO Rigger Level I or Rigger Level II credential creates a portable, auditable baseline. The card is easier to verify during onboarding than an open-ended claim about time in the field, and it supports a consistent approach to risk management.
The problem comes when the credential is treated as a complete assessment instead of one part of it. A card can establish eligibility to enter the site without showing whether the rigger has handled the equipment being installed, understands the lift plan, can identify a questionable attachment point or will stop work when field conditions no longer match the plan.
An experienced rigger may also understand load behavior, sling angles and communication under pressure yet struggle with a standardized exam. It doesn’t eliminate the contractual requirement, but rather demonstrates why testing and field competence must be developed together.
What Rigger Level I and Level II establish
CCO’s two rigger credentials cover different levels of responsibility. Rigger Level I applies to simple, repetitive tasks in which the load weights, center of gravity and rigging configuration are provided or known. Its scope includes inspecting, selecting and attaching rigging, understanding basic hitches and capacities, and recognizing hazards.
Rigger Level II builds on that foundation, covering the estimation of load weight and center of gravity, as well as proficiency in identifying lift points, selecting rigging, accounting for load-angle factors and understanding load dynamics. Rigger Level II credential holders are expected to perform those tasks without supervision.
Both credentials require written and practical examinations, making the card more than proof of attendance. At the same time, CCO eligibility does not require a documented number of years in the field. Two people can pass the same examinations without bringing the same breadth of experience to the job.
The credential therefore answers an important – but limited – question: Did this person demonstrate the knowledge and practical skills covered by the exam? It does not show the full range of loads the person has handled or how consistently that knowledge is applied when conditions become less controlled.
Test preparation is not field training
While exam preparation helps a candidate understand the material and demonstrate it under test condition, field training must turn principles into repeatable decisions when the lift is inside an operating facility, the laydown area is tight, an attachment point is not where the drawing showed it, or a delivery delay has compressed the work window.
It’s judgment that cannot be reduced to memorizing terminology or rehearsing a practical exam, developing instead through instruction, supervised application and feedback. A trained rigger needs to know not only how to select and inspect components, but also when information is incomplete, when assumptions must be checked and when the safest decision is to pause the operation.
Training also establishes how the crew works as a unit, as a lift depends on clear roles and disciplined communication among the rigger, signal person, operator and lift director. Exam performance doesn’t replace an understanding of the organization’s planning process, stop-work expectations or escalation path.
None of this diminishes certification. Narrow test preparation may produce a passing result; training is what makes the underlying knowledge available when the job stops looking like the test.
Train first, then let the credential follow
A stronger model treats certification as the finish line of training, not the starting point. Workers should build and demonstrate the relevant skills before they are assigned to perform them on a client’s project. Credential preparation can then organize that knowledge around a recognized standard and close gaps identified during training.
The paths will not be identical for every rigger. For example, a tenured worker may need focused preparation to translate familiar calculations into exam language, while a new worker may need more instruction and supervised practice. The process should measure what each person can do instead of assuming experience will appear after the test.
Meanwhile, certification should not end the evaluation – employers still must determine whether a rigger is qualified for the work assigned, and project teams must match responsibility to the proper credential and demonstrated capability. It is imperative that qualification remain connected to the work in front of the crew.
For a general contractor, owner or insurer evaluating a rigging provider, the most useful questions go beyond whether cards are current: How does the provider decide who is qualified for a particular lift? How are Rigger Level I and Rigger Level II personnel assigned? What happens when conditions differ from the plan? How are skills checked after certification?
The card answers a necessary question about baseline knowledge and contractual eligibility, and training answers the harder question about execution.
A professional rigging operation should be able to explain both – not simply whether its people hold the credential, but how they developed the ability to use it when the load is in the air.
