Controversy over the Use of the Stanford-Binet Intelligence Scale
By Inderbir Kaur Sandhu, Ph.D
Q:
Can you please tell me why is there so much controversy over
the use of "Stanford-Binet Intelligence Scale" with
children? Thank you.
A: Let me start with some bit
of history to understand the controversy better. As is
known, Lewis Terman and his colleagues designed the
Stanford-Binet which was developed by Alfred Binet. The
scale was specifically designed to identify extremely
advanced children. As such, no other individual intelligence
test was designed with the above intent, and other
intelligence tests constructed were not able to capture the
full strengths of the abilities of highly, exceptionally and
profoundly gifted children. Therefore, the Stanford-Binet
Intelligence Scale remained the test of choice for
identifying highly gifted children until 1986.
However, the 4th edition of the Stanford-Binet Intelligence
Scale had a ceiling of 148, since there were not enough
children in the norm sample who scored beyond 148 to warrant
higher scores. Higher scores (149 to 164) were statistically
extrapolated by rather than basing it on normed samples. It
was also found that rather than the gifted population, items
for the test were more appropriately designed for the
general population. This is based on the observation of
James Flynn who found that the general population is
increasing in intelligence by approximately a third of an IQ
point per year across the globe (this is still being debated
strongly and perhaps applies more to the extremes in
intelligence).
Because of all these controversies, a good number of
psychologists who are familiar with gifted children prefer
to use the older version of the scale. However, parents are
usually quite confused as it is expected that the latest and
revised scale is always better than the older one. Apart
from that, the newer scale with lower ceilings somewhat
disguise the exceptionally gifted child as moderately
gifted. Hence, it is not uncommon for psychologists who work
with exceptionally gifted children to offer the SBL-M as a
second test when children have hit the limits of the first
test.
Currently the Stanford-Binet is in its 5th edition (SB-5).
There are still controversies on this latest edition
although it had been revised well. Over a span of time, the
purposes of intelligence testing have changed and the SB-5
now bears little resemblance to Binet's original work!
Hope the brief explanation would shed some light on the
scale.
