| Abstract: | The type and frequency of a variety of clerical errors were investigated in 200 protocols from both the 1949 and 1974 editions of the WISC. The rate of errors was grossly the same for the records both at a psychiatric facility and at a large school system. Nearly 90% of the combined examiners had made at least one error, and 46% of the protocols contained one or more errors. While the rate was slightly lower in the school setting, there were no significant differences obtained when students vs. practitioners or Master's vs. Master+ level of training were considered. Despite the high error rates, in most cases there was little impact upon IQs. Potential consequences of such errors and a discussion of ways to lower the rate are presented. |
