The document is a student manual and teacher's manual for a simulated office practice class designed to give students training in a business office on school premises. In the simulation, students perform as office personnel and as customers and creditors. The first part of the guide, directed to students, contains: general information on the Patriot Company (a simulated office equipment company), employee information, objectives of the simulation, room layout diagram, company organization chart, descriptions of job duties for 19 company positions, a catalog-price list, simulation customer names, simulation creditor names, and forms for evaluation of employees. The detailed teacher's manual lists: materials to be prepared prior to simulation, steps to simulation, suggestions for obtaining supplies, forms and supplies needed for a 12-week simulation, equipment sources, special suggestions, procedure for distribution of mail, company balance sheet, and additional student and teacher-developed activities. Also included are sample scripts for the simulators to follow, cash sales list, credit limits of customers, inventory list, and instructor evaluation forms for student performance in each of the 19 company positions. A brief description of 50 forms used in the simulation and samples of each form conclude the manual. (MS)
