Abstract

An investigation of the difference in school psychologists' clerial error rates between WISC-R and WISC-III showed that WISC-III appears no less prone to examiner errors than WISC-R. Errors were found on 38% of WISC-R protocols and 42% of WISC-III protocols. On WISC-III, the decline in Full Scale IQ-changing errors over a period of 18 months was statistically reliable.
