Abstract
Numerous studies have indicated that graduate students and professionals alike make errors on Wechsler intelligence test protocols, which decreases the reliability and, thus, the validity of obtained test scores. This paper analyzed literature on Wechsler protocol scoring errors and proposed several hypotheses for consistent findings of examiner errors. Poor instructional preparation of students and ambiguity of scoring criteria in test manuals were cited as two probable explanations. Carelessness on the examiner's part as evidenced by incorrect mathematical calculations and incorrect scores on more objective subtests (such as Coding and Digit Span) was mentioned as another probable hypothesis. The examiner-examinee relationship and job-related factors (such as stress and excessive caseloads) also may be contributing factors. Empirical research is needed to determine more clearly the degree to which these hypotheses explain examiner difficulties in Wechsler test scoring.Keywords
