I was trying to locate something that might easily answer your question -- not sure I succeeded. Test instrument such as WISCIII comprise severate categories of testing -- and those have "subtests." Sometimes the scores are scattered and can indicate specific weaknesses or disabilities. Many psychologists use the Wechsler Intelligence Scale for Children (WISC), third edition, to identify learning disabilities. The WISC is an intelligence test that can be administered only by a licensed psychologist or tester. The scores may be interpreted in several different ways by specialists and nonspecialists alike who understand the significance of the numbers. A WISC score is derived from the scaled combination of two sets of subtests, Verbal and Performance. Each of these two categories has its own total, which is derived from the scaled combination of 6 subtest scores. The Wechsler Intelligence Scale for Children(r) - Fourth Edition, which added several new subtests and eliminated others, has recently become available. The WISC-IV comprises 10 core and five supplemental subtests, which are grouped into four indices -- verbal comprehension, perceptual reasoning, working memory and processing speed. Scores from each index, based on the core subtests only, are combined to create a child's total score, or Full Scale IQ (FSIQ). The following information relates to the The Wechsler Intelligence Scale for Children (WISC) Third Edition. VERBAL Information - fund of general knowledge Similarities - verbal abstract reasoning Arithmetic - numerical reasoning, attention and short-term memory for meaningful information Vocabulary - knowledge of word meanings Comprehension - social comprehension and judgment Digit Span - short-term auditory memory for non-meaningful information PERFORMANCE Picture Completion - attention to visual detail Coding - visual-motor skills, processing speed Picture Arrangement - attention to visual detail, sequential reasoning Block Design - visual abstract ability Object Assembly - part-whole reasoning Mazes - graphomotor planning, visual-motor coordination and speed Each subtest delivers a scaled score, which may range from 1 (lowest) to 19 (highest). The above was taken from https://web.archive.org/web/20060105021025/http://ericec.org/faq/gt-ldtst.html and relates to gifted, however, the premise is the same. You can learn more about understanding test scores on the home page and library page at https://web.archive.org/web/20070804043640/http://www.adhd-add.info/. Be sure and ask for a copy of your child's wirtten report, inclusive of subtest scores.
