When subtest scores are in parentheses, this means that these scores are not computed as a part of the overall composite score. If you look at your child's scores, you will see that (Digit Span) and (Symbol Search) are in parentheses. On the WISC-III, the Digit Span, Symbol Search and Mazes subtest scores are not included in the Verbal, Performance and Full Scale IQ scores. They are used to develop other composite scores.
