The WAIS is
primarily pen and paper, and the WISC is both pen and paper and practical ability. The Bayley
consists of trying to get the child to play the same game that you are playing.
“IQ Tests” are one of the more commonly used and abused psychological instruments ever devised.
Always be aware that IQ tests measure one and only one type of intelligence: that which is required
to succeed in formal educational institutions. Realistically speaking, the IQ score is the best single
predictor we have of academic achievement ability, but IQ tests are objective rather than projective
measures. Examples of IQ tests with which you, as students, are most familiar are the SAT or ACT.
If you go past a baccalaureate degree in your educational process, you will have the traumatizing
experience of becoming acquainted with the GRE, LSAT, MCAT, DCAT, or whatever applies to your
area of graduate interest.
IQ scores can only be interpreted in a relative sense. Your score is based on standardized norms
and indicates how well you, as an individual, performed on a given test instrument relative to other
individuals of the same age and background, when tested under the same constraints. The normal
curve, or normal distribution, is used to define the distribution of IQ scores.
Once more, relativity is the essential concept. Whether or not your child is “gifted” in a positive or
negative manner is relative to where he/she scored in comparison to other children who took the
same instrument, at the same time, under the same conditions. When looking at IQ scores and
interpreting them, you will frequently hear the following terms. They are key to understanding
relativity and IQ measurement.
Stability refers to the individual’s relative standing over time.
Change refers to the change in a given individual’s absolute scores over time.
In summing up, IQ scores are useful to us in determining the individual’s potential for success in
an academic environment but beyond that function their applicability fades rapidly. As students
and as future parents, you need to be aware of the applications in which the IQ test is relevant, and
in which it is not.
