Your CCO Card Is Not Enough: OSHA's Separate Employer Evaluation Requirement
OSHA requires crane operator certification and, separately, a documented employer evaluation on the specific equipment. The second requirement took effect 7 February 2019 and is the one most crews miss.
Problem this solves
This guide solves the next-step problem for Crane candidates: it explains what matters, then gives you a direct way to test that knowledge with practice questions instead of guessing what to study next.
Two Requirements, Two Dates
Almost every crane operator knows OSHA started requiring certification on 10 November 2018. Far fewer know there is a second, separate requirement that landed three months later. 29 CFR 1926.1427(c) requires the employer to ensure each operator is certified or licensed to operate the equipment, at no cost to the operator. That is the certification requirement, and a CCO card satisfies it. 29 CFR 1926.1427(f)(1) requires something different: the employer must ensure each operator is qualified by a demonstration of the skills and knowledge necessary to operate the specific equipment safely. Paragraph (k)(2) gives the date: "The evaluation and documentation requirements in paragraphs (a) and (f) are effective on February 7, 2019." Certification is portable and generic. Evaluation is employer-specific and equipment-specific. Holding a valid CCO card does not satisfy the evaluation requirement, and passing an employer evaluation does not satisfy the certification requirement. You need both, and the employer must document the second one.

What the Evaluation Actually Covers
The evaluation is not a paperwork exercise the office does once. Under 1926.1427(f), the employer must evaluate the operator on the equipment the operator will actually use, in the conditions the operator will actually face. That means the evaluation is tied to the machine and the work. An operator evaluated on a 40-ton telescopic boom truck crane doing straightforward pick-and-carry work has not been evaluated for a 300-ton lattice boom crawler running a critical lift over an occupied structure. If the equipment or the operations meaningfully change, the employer's obligation to evaluate does not carry over automatically. The practical consequence for an operator changing employers: your CCO card travels with you, your evaluation does not. A new employer must conduct and document its own evaluation before you run their iron.

Training Before Certification
1926.1427(b) covers the period before you are certified. An operator-in-training must receive sufficient training through a combination of formal and practical instruction, and must be continuously monitored on site by a qualified trainer while operating. "Continuously monitored" is doing real work in that sentence. It is not a supervisor within radio range. The trainer has to be in a position to intervene, which in practice means within sight of the operation and able to communicate with the operator without delay. This is the paragraph that catches small contractors who put an experienced but uncertified hand in the seat because "he has run cranes for twenty years." Experience is not a defence. There is no grandfather clause in 1926.1427.
How Long Certification Lasts, and What Recertification Actually Requires
OSHA sets the outer bound: certifications issued under an accredited testing organization are "valid for 5 years" (1926.1427(d)(4)). Employer audited-program certifications are also valid for five years (1926.1427(e)(6)(ii)). NCCCO's own handbooks match this: CCO Mobile Crane Operator certification is valid for five years. Recertification is lighter than most operators assume. NCCCO's candidate handbook states that recertificants must pass the Mobile Crane Operator written examination(s), comply with CCO's Substance Abuse Policy, and comply with CCO's Code of Ethics. Candidates with at least 1,000 hours of crane-related experience during their period of certification do not need to take the practical exam to recertify. The penalty for letting it lapse is real. Candidates whose certification has lapsed must take both the written and practical examinations again. The 1,000-hour waiver only helps you if you recertify before the card expires — which is an argument for calendaring the renewal window rather than the expiry date.
The Documentation Nobody Keeps
The requirement in 1926.1427 is for the evaluation to be documented. In an OSHA inspection following an incident, the questions are predictable: who evaluated this operator, on what equipment, when, and where is the record? A sufficient record identifies the operator, the equipment type and configuration the operator was evaluated on, the operations covered, the name and qualification of the evaluator, and the date. Keep it accessible on site rather than in a filing cabinet three states away. The common failure mode is not refusal, it is drift: a crew evaluates operators properly at hire, then adds a new crane to the fleet and nobody re-evaluates. The card is still valid. The evaluation no longer covers the machine.
What This Means for Exam Prep
The Core written exam covers OSHA 1926 Subpart CC, and the certification-versus-evaluation distinction is exactly the sort of regulatory detail that appears in questions phrased as scenarios rather than definitions. A question may describe an operator with a current CCO card starting work with a new employer on an unfamiliar machine and ask what is required before that operator runs the crane. The answer is the employer evaluation, and candidates who only memorised "certification is required since November 2018" pick the wrong option.
