Each course covers the individual subject in great detail and does not require the purchase of any additional books or materials. Each of the courses allows the student to work at his own pace, away from the work place.

• Please note this course is available in only the United States and Canada. It is not available Internationally

  The student is given several hundred questions to answer and is told where to find the answer in the reference material, forcing the student to read every page of the manual. When all of the answers are completed successfully and returned to the Institute, the student is sent a final examination that must be completed to receive his or her diploma.
