This two-day, very intensive class is only offered to members who are registered to take the CCO
written exams. The fact that this class is termed a “refresher” implies that students already have had
some training and experience necessary to pass the written exams. Due to the comprehensive nature
of the CCO written exams, not all subjects will be covered in depth. Those that need more training are
encouraged to take the 40 hour Crane I class.
