The earliest portion of the PDD examination process during which the examinee and examiner discuss the test, test procedure, examinee’s medical history, and the details of the test issues. The pretest interview also serves to prepare the examinee for the testing. The length of the pretest interview ranges from 30 minutes to 2 hours or longer, depending on the complexity of the case, examiner-examinee interactions, and testing technique. All PDD techniques use pretest interviews.
