The on-the-job training guide was developed to assist food service supervisors in preparing, presenting, and evaluating a Job Instruction Training (JIT) lesson, a method which employs step-by-step learning of job-related tasks. Part 1, preparing for a JIT lesson, discusses the checklist of duties, the job description, the skills inventory, the training schedule, the schedule for refresher training, the individual development record, the task procedure, and the lesson plan for a lesson on preparing dishes for washing by hand or by machine. Part 2, conducting a JIT lesson, explains the four steps involved in training: preparing the worker, presenting the task, trying out performance, and following through. Part 3, evaluating a JIT lesson, discusses improving training procedures through instructor self-evaluations, and worker and observer evaluations. Part 4, providing more examples, repeats the procedures used in part 1 for use in preparing training lessons for storeroom clerks, assistant cooks, salad makers, tray assemblers, and cook's helpers. Part 5, "Good Luck in Your Training," contains blank forms useful in preparing JIT lessons. (JR)
