The hours are assigned for each class based on specific state requirements. Some states require a certain number of questions and/or a minimum amount of time spent viewing the course.
Our courses are written by nationally-recognized training directors who include the same amount of material in the online version as is covered in a classroom course. They assign the hours accordingly.
Most courses also include a Final Exam.
NOTE: The Course Details tab on each course will tell you how many credit hours each approving state has chosen to grant per course. Each state's own state licensing information website will also go into detail on requirements and credit hour determinations.
