RIAS Score Interpretation
By Inderbir Kaur Sandhu, Ph.D
My daughter was assessed for the gifted program at our school and met
criteria in every way, except IQ. I find her RAIS scores very curious.
On the short IQ assessment (can't remember the test name) she was in the
The following are her scores:
T. %. Range
Guess what 64.
Verb reas. 76
VI Index. 99. Very superior
Odd item. 43
What's missing 46
Nonverbal index. 30. Average
Composite. 82. High average
My daughter was 7 & in 2nd grade in her last week of
2nd grade (may). I find it odd that there is such a discrepancy in
verbal/non-verbal. Also, such a difference in the composite score and
the short test score, though I recognize there is a higher margin of
error in the short scores.
I'd like to have my daughter retested by z private tester. There were no
notes referencing any problems administering the test, but something
Any feedback would be appreciated. This test is from 2014. My daughter
continues to excel with absolutely no effort & Is growing more
frustrated with her classes.
The Reynolds Intellectual Assessment Scale (RIAS is an individually
administered intelligence test, applicable to all ages from 3 to 94. It
comprises two subtests that assess verbal intelligence (VIX) and two
subtests that assess non-verbal intelligence (NIX).
The subtests that compose the VIX assess verbal reasoning ability along
with the ability to access and apply prior learning in solving language
related tasks. Although labelled the Verbal Intelligence Index, the VIX
is also a reasonable approximation of crystallized intelligence. The NIX
comprises subtests that assess nonverbal reasoning and spatial ability.
Although labelled the Nonverbal Intelligence Index, the NIX also
provides a reasonable approximation of fluid intelligence and spatial
These two indexes of intellectual functioning are then combined to form
an overall Composite Intelligence Index (CIX). By combining the VIX and
the NIX into the CIX, a strong, reliable assessment of general
intelligence (g) is obtained. The CIX measures the two most important
aspects of general intelligence according to recent theories and
research findings: reasoning or fluid abilities and verbal or
crystallized abilities. Each of these indexes is expressed as an
age-corrected standard score that is scaled to a mean of 100 and a
standard deviation of 15. And as a rule of thumb, a score that is about
two standard deviation away from the mean is within the gifted range for
most tests and for most placements in gifted programmes.
Your daughter obtained a Composite Intelligence Index (CIX) percentile
of 82. This level of performance falls within the high average range of
scores. Her Verbal Intelligence Index (VIX) percentile is much lower at
99, which falls within the very superior range of verbal intelligence
skills. Her Nonverbal Intelligence Index (NIX) percentile at 30 falls
within the average range of nonverbal intelligence.
It appears quite strange that the scatter is so large given that she has
been performing well at school. Try talking to the test administer to
clarify your doubts first. Such scores may indicate a learning
difficulty – see if she struggles in non-verbal skill areas. If you are
not satisfied with the clarification from the school, it would be good
to test your daughter privately and get a much better idea of her
strengths and weaknesses. If she has been frustrated in her learning,
there is a high chance that there is no ability-educational match in her
class leading to possible frustrations. Do seek help as soon as
Best of luck!.
