* The reuse ratio is the number of learning hours used divided by the number of learning hours available.
Learning hours used are calculated by multiplying the number of hours available by the number of employees who took them.
Learning hours available are measured by the source as a one-time count that does not consider how many times a course or content was offered: An eight-hour workshop counts as eight hours, whether it was presented once, daily, weekly, or monthly..
