Hi bigtoe,
The Wechsler Intelligence Scale for Children test is the universal
standard which School Psychologists use most often and is standardized
for children from age 6 to 16.
"The test, itself, is divided into two main sections. The Verbal Scale
measures how well children are able to express themselves verbally and
how well they are able to understand what is being said to them. The
Performance Scale measures the nonverbal areas of being able to
perceive spatial relationships; such as in putting puzzles together,
and being able to transfer visual information rapidly."
"Using test interpretation, the three I.Q. scores and the specific
pattern of strengths and weaknesses indicate how well the child is
able to learn and whether there are any specific learning
disabilities. This information is then used to predict at what
academic level the child should be functioning. In this way, diagnoses
of learning impairments are possible."
Within the Verbal Scale are the following subtests and what they measure:
Information (measures a child's range of factual information)
Similarities (measures a child's ability to categorize)
Arithmetic (measures the ability to solve computational math problems)
Vocabulary (measures the ability to define words)
Comprehension (measures the ability to answer common sense questions)
Digit Span (short-term auditory memory)
Within the Performance Scale are the following subtests and what they measure:
Picture Completion (telling what's missing in various pictures)
Coding (copying marks from a code; visual rote learning)
Picture Arrangement (arranging pictures to tell a story)
Block Design (arranging multi-colored blocks to match printed design)
Object Assembly (putting puzzles together - measures nonverbal fluid reasoning)

Administration and Scoring:
"The Wechsler Intelligence Scale for Children test has two batteries
of subtests grouped into two general areas: 1) Verbal scales; and 2)
Performance scales. The Verbal scales measure general knowledge,
language, reasoning, and memory skills, while the Performance scales
measure spatial, sequencing, and problem-solving skills."
"The tests are administered to individual examinees by trained
examiners, using a complex set of test materials. Testing requires
approximately ninety minutes. Raw scores on each test are converted to
standard scores with a mean of 10 and a standard deviation of 3. Scale
scores in the Verbal battery are summed and converted to a Verbal IQ
score; the same is done for the Performance scale scores which yield
the Performance IQ score. In turn, the Verbal and Performance IQ
scores are summed and converted to obtain the Full Scale (overall) IQ
score. The Verbal, Performance, and Full Scale IQ scores are normative
IQs, having a mean of 100 and a standard deviation of 15."
Full Scale scores beyond 130 place an individual in the superior or
"gifted" range.
Scores between 120-129 are classed as "very high."
Scores between 110-119 are "bright normal."
Classifications of other scores are as follows:
90-109, average
85-89, low average
70-84, borderline mental functioning
50-69, mild mental retardation
35-49, moderate retardation
20-34, severe retardation
below 20 to 25, profound retardation

If you are interested in having the test done on your child, perhaps
the school where your child attends will inform their Educational
Psychologist (EP).
"Specialist Teachers are often presented with Educational
Psychologists' Reports from which from they are expected to
extrapolate information to inform teaching and learning objectives.
This information sheet is designed to help teachers understand what
cognitive skills the EP tests are assessing and the implications these
may have on a learner's ability to access curriculum subjects.
The Wechsler Intelligence Scale for Children is the one of the most
common battery of psychometric tests used by EPs; the other is the
British Ability Scale. EPs also use a number of other tests in their
reports but this information sheet will only be looking at the WISC.
The WISC is designed to assess children's intellectual abilities or
IQ. It was first published in the USA in 1949, revised and
re-standardised in 1974, a British version followed. In April 1992 the
WISC III UK was published..."
