All students were found to make errors, with substantially more errors being detected by the faculty member than by self or peers. 91.3% of students were rated as having demonstrated competency in administration and scoring. Video recordings and test protocols from a role-played test administration were analyzed for errors according to a comprehensive checklist with self, peer, and faculty member reviews. Twenty three post-graduate psychology students underwent training in using the WAIS-IV according to a best-practice teaching model that involved didactic teaching, independent study of the test manual, and in-class practice with teacher supervision and feedback. There is a need for an evidence-based approach to training professional psychologists in the administration and scoring of standardized tests such as the Wechsler Adult Intelligence Scale (WAIS) due to substantial evidence that these tasks are associated with numerous errors that have the potential to significantly impact clients’ lives. 2School of Psychology and Speech Pathology, Curtin University, Bentley, WA, Australia.
