This testbook contains objective (multiple choice) tests covering each topic in the companion Auto Parts Workbook (see note). The book is arranged so that each section can be detached and given to the student as the test subjects are covered in class. (Answers are not included.) There are an average of ten questions for each of six units. Unit A, scope and opportunity, covers the auto parts industry and opportunities in the field. Unit B, areas of responsibility, includes filling and shipping orders, receiving, bin arrangements and stock maintenance, pickup and delivery, introduction to counter sales, the shop counter, and the machine shop and related sales. Unit C, cataloging systems, tests student knowledge of factory parts systems and jobber and independent systems. Unit D, inventory and control, covers inventory systems, stock control, and ordering and purchasing. Unit E, counter sales, includes parts terminology, divisions of counter work, customer relations, and how to sell. Unit F, displays, tests the areas of display merchandising, reasons for displays, and ways to use displays. Prefatory notes discuss the importance of confidentiality and ways to modify or supplement the test materials. (CT)
