Aaron, Job descriptions are vital for all concerned. This means the employer, school, instructors, and career services staff all need to know what is required for each career you train for. In fact, we find it helpful to review job descriptions in class. Students need to know why they are learning certain skills and theory and how it will be used on the job. They need to understand the demands of the job and and be able explain how they can meet them. Thanks, Susan Dr. Susan Schulz
