The PQ&R Corporation has developed a collection of training materials and skills tests for activities that accurately represent the types of tasks performed by employees in a production environment. Before any instruction is given, each trainee is asked to perform the training battery—a series of tasks for which they are about to receive training. Immediately on completion of instruction, trainees are again asked to perform the training battery to assess the effectiveness of instruction. After performing the battery for the second time, the trainees become employees of PQ&R. On completion of their six-month introductory period of employment, trainees are required to perform the training battery a third time.
