It is vitally important to find the right individual to test you child. Many intellegence tests are used to identify child with learning disabilities and mental deficiencies in addition to high intellectual abilities, and testers tend to specialize in one area or the other. A good WISC tester is one who has tested many gifted children and "gets them." My tester, for example, has a full questionnaire that parents complete and turn in prior to testing to give her a feeling for the child. She also includes an introvert versus extrovert scale, as this is a common defining characteristic for gifted children. In adition to providing results, she also evaluates them and provides a full list of recommendations. These can include appropriate schooling situations, organizations to pursue, and specialists to see regarding areas of concern.
A gifted child is rarely gifted across the board. One of the hallmarks of gifted children is their asynchronous development. Understanding the areas of relative strength and weakness will help you as the parent guide your child and his or her teachers.
If this were my child I would be very tempted to find a new tester. I would also have the most recent WISC (the IVth edition) administered. Before bringing my child in I would agree on what will be provided by the tester. I would want results broken down by subtest, recommmendations for home and school, referals to appropriate specialists and a face to face consultation.
I found that there was a section in the book Upside Down Brilliance by Linda Silvermann that discussed the WISC subtests which I found useful.
Good luck.
