Students provide the company a letter of credit signed by two endorsers, typically the student's parents, in which the endorsers agree to be responsible for up to $500 each if the student fails to pay any money owed to the company at the end of the summer. Students entering the program attend a week-long training program in Nashville, Tennessee. They are responsible for the cost of travel and their personal expenses. At the conclusion of the training, students are assigned to a sales area outside their home or school states. Sales areas are predominantly suburban or rural.
