Accuracy of IQ Testing
By Inderbir Kaur Sandhu, Ph.D
Q:
My daughter was tested for her
inborn intelligence and it turns out that it is above average
by 51 points. Teacher claimed that she could be gifted due
to her observation in class through a series of games and
activities for brain training. Hence when an IQ test was
administered on her, she has IQ of 100 points, which is
average.
Teacher claimed she was disappointed as it could be a
misjudge. She used TONI 2 test. She also said that she did
well for the first few sections but didn't sustain as she
didn't want to carry on to complete the test items. She did
complete it at last. Why is this so? Will an IQ test for 4
years and 3 months old child be accurate at this point? I am
puzzled. when I spoke to my daughter, she claimed she didn't
like to do such work because its not fun at all. She hates
doing it and told me she doesn't want to do it again. Please
advise. Thank you.
A:
The TONI 2 (Test of Nonverbal Intelligence, 2nd edition) is a language-free
measure of abstract problem-solving ability. This test is
free of linguistic, motoric, and cultural factors and can be
used for a range of age group; 5 through 85 years of age.
Hence, in this case, your daughter is younger than the usual
minimum age. For someone with above average inborn
intelligence scores, I can understand your concern when her
scores were average for the IQ test.
It must be noted that IQ tests are, and were
originally designed to generate numbers that are useful in
assessing academic aptitude within a given culture. They give
us clues as to the probable success of children in our current
educational system, although with less than perfect accuracy.
Therefore, one should never rely too much on these numbers. In
your daughter's case, it is obvious why she may not have done
as well as you would like her to. She had indicated it herself
- that it was not fun at all. Perhaps, at this point you should
not test her further. I believe you know of her capabilities
and thus are able to provide her with the necessary materials
to further develop her potentials. If you want a retest,
perhaps you should wait until when she is ready.
IQ tests should be used for specific purposes,
such as to find out if the child has a learning disability or
mentally challenged, if the child is gifted, if a child
exhibits a discrepancy between ability and achievement and if
the child qualifies for special education. If tests are used
for labeling purposes alone, this may not be very healthy and
will only turn parents into competitive adults as expectations
are usually rather high. My advise is allow her to develop
naturally and with some help to enhance her potential and allow
her to decide whether she wants to take a test, unless if it is
for a specific purpose.
