Student records of 170 learning disabled students from two area agencies were examined to determine the stability of WISC‐R test scores administered as part of the 3‐year reevaluation of students required by Public Law 94–142. The WISC‐R had been readministered to 150 of these students. Stability coefficients were .72, .70, and .74 for the Verbal, Performance, and Full Scale IQ scores. Changes in Full Scale scores were 4 points or less for 52% of the sample. Changes greater than 15 points were noted for 4% of the sample. Results suggest that WISC‐R scores are reasonably stable over a 3‐year interval, and routine readministration of the WISC‐R should not be required or encouraged.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
