Grove TLL

These sample questions are intended to convey something of the style and content of the National Operator Certification Program examination developed and administered by the National Commission for the Certification of Crane Operators (NCCCO). They are not actual test questions, nor do they attempt to address all of the areas of knowledge tested on the CCO certification examination. Response to these questions is not necessarily an indication of performance on the CCO examinations.
