Description
The study investigated the stability of the WISC‐R IQ scores of 32 exceptional students (24 males, 8 females) over a six‐year interval. The sample was composed of 20 learning disabled and 12 mentally handicapped students who ranged in age from 6–5 to 16–11. Analyses of variance for repeated measures and product‐moment correlations were used to analyze the data. Test‐retest findings indicated that the rs ranged from .53 to .87, with a median value of .74, with four of the nine values below .70. Implications for clinicians in terms of the importance of reevaluation of exceptional students are discussed.
