Difference in IQ level
By Inderbir Kaur Sandhu, Ph.D
My step-daughter could not talk until she was three years
old. Her development was very slow and she was not able to
read when she was in the first grade the first time. We had
her repeat the first grade and had her retested. The test
the school first gave her indicated there was not a learning
problem. We asked them to retest her and the results showed
that her IQ was below 70.
When she was in the fourth grade her IQ was 68. She is now
in the 7th grade and the school just told us that her IQ is
77. Is this possible? She has a difficult time and still is
not working on grade level. Please advise us what to do or
what test they can give her?
A: Unfortunately, you did not
indicate the tests used to determine her IQ. However, on a
standardized IQ test, it is possible for the IQ to vary a
little (just a few points usually if given the same test in
a two-year gap period) but drastic changes may be a
different problem entirely and can be due to many factors,
usually health related. Of course, different IQ tests may
likely produce different results, especially if the tests
are not standardized or normalized.
What you need to do is to make sure the test administer is a
standardized test and that it is being interpreted by a
qualified and experienced tester. She may well have a
learning problem which has not been attended to. If the
school is not able to help, get a recommendation to see an
educational psychologist who is able to give her an
appropriate test (perhaps even a diagnostic test) to
determine the kind of treatment required.
