Cr. Reynolds et al., NORMATIVE TABLES FOR CALCULATING THE WISC-III PERFORMANCE AND FULL-SCALE IQS WHEN SYMBOL SEARCH IS SUBSTITUTED FOR CODING, Psychological assessment, 8(4), 1996, pp. 378-382

titute Symbol Search, a new subtest, for Coding when calculating Perfo
rmance and Full Scale IQs on the Wechsler Intelligence Scale for Child
