The Possibility a Learning Disorder Based on IQ Test Scores
By Inderbir Kaur Sandhu, Ph.D
My 7 years old daughter recently took the Kaufman Brief Intelligence
Test - (K-BIT 2) and Kaufman Test of Educational Achievement – Brief Form (KTEA-II-Brief).
We were asked if she had any learning disabilities like dyslexia due to
her difference in scoring. I'm not understanding the scoring or why it
shows she could have any disability. Can you help explain? Here are her
SUMMARY OF TEST SCORES

The Kaufman Brief Intelligence Test 2 is a short cognitive assessment
that, like other cognitive tests provide information about a student's
intellectual strengths and weaknesses, as well as insight into her/his
overall cognitive potential. The test gives general information about a
student's abilities compared to others his or her age in several areas.
The scores are typically described in Standard Scores. Standard Scores
have a mean (average) of 100. Anything within 10 points from 100 is
usually considered Average. Your child's score of 112 places her in the
High Average range (typically 110-119 is considered High Average). All
her scores are similarly scattered indicating rather meaningful scores.
Academic achievement tests measure specific academic skills compared to
other children at the same grade or age level as in the KTEA. In a
typical situation, a student's achievement scores will be quite similar
to the cognitive ability scores. However, this is not the case with your
While her average scores in cognitive ability measures in the High
Average range, he achievement scores is quite far off. When the scores
are well below measured cognitive potential, it may signify a Learning
Disability if other factors are present. However, there are a variety of
reasons that cause academic achievement to be discrepant from cognitive
abilities. You would need to speak to the tester and school regarding
As she appears very capable of learning, any learning disability could
cause low scores as in her case and needs to be addressed immediately.
Intervention is available for such disabilities and the earlier the
invention the better the results. Her achievement scores clearly shows
struggle in learning and the need for some aid. You may need to further
test her to rule out any learning disorder; though the difference
between the ability-achievement score does indicate a learning concern.
Do speak to the school for further testing and invention as soon as
possible. Good luck!
