The purpose of the research was to investigate the effects of different training methods on inspector accuracy and to assess the effects of the use of a job aid on the application of trained inspection skills in a simulated work setting. Thirty subjects were trained to identify incorrect elements in four types of geometric figures. Subjects were randomly assigned to two groups that received two different types of training for error identification. Following training both groups were tested in four inspection performance sessions. Both groups were given access to a job aid in the performance sessions. Both the relative effects of the training methods and of the job aids on performance were assessed. There were no significant effects due to type of training, and subject errors did not vary systematically with the presence/absence of a job aid.
