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.
