RIAS Scores for Gifted Education Placement
By Inderbir Kaur Sandhu, Ph.D
What are the required scores to be considered for gifted classes when it comes to the
RIAS test, my son who is a kindergarten was given this exam and scores 129, 128.
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). A verbal and
nonverbal supplementary memory test can also be administered (yields
Composite Memory Index score - CMX). It appears that the memory test was
not administered for your daughter, as it is supplementary.
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 labeled the Nonverbal Intelligence Index, the NIX also provides
a reasonable approximation of fluid intelligence and spatial ability.
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 deviations away from the mean is within the gifted range
for most tests and for most placements in gifted programmes (in this
case, 130). However, different schools may have slightly different
criteria (and eligibility tests) and further testing may be required.
You did not indicate the scores clearly; so I would assume that your
daughter obtained a Composite Intelligence Index (CIX) of 128 or 129.
This level of performance falls within the range of scores designated as
high average. It would be best to find out from the school more
information about your son's scores by looking at the breakdown of the
scores. Good luck!
