Interpretation of K-BIT 2 Scores
By Inderbir Kaur Sandhu, Ph.D
My son is 5 years old and obviously very intelligent. He was recently
given the K-BIT 2 test through his school. These are the scores I
K-BIT Composite Score 11
There is no explanation of what these scores mean or where he falls
intellectually. Only that he doesn't meet district criteria for the
The KBIT-2 is a screening measure of intelligence comprised of two
subtests: Matrices (non-verbal) and Vocabulary (verbal). In theory, the
verbal subtests measure crystallized ability and the non verbal subtests
measure fluid reasoning. The Verbal portion of the KBIT-2 is made up of
two subtests, Verbal Knowledge and Riddles. These measure verbal, school
related skills by measuring an individuals word knowledge, verbal
concept formation, reasoning ability and range of general information.
The Non Verbal portion is made up of the Matrices subtest and measures
the ability to solve new problems by assessing ability to perceive
relationships and complete visual analogies.
Scores from these two subtests are combined to form the IQ Composite,
which serves as the measure of intelligence on the KBIT-2. The composite
standard scores have a mean of 100 and a standard deviation of 15.
Scores between 90 and 110 are considered average.
It appears that you son scored above average for Vocabulary; and in the
average range for Matrices. However, I am not able to make out the
reason for the IQ Composite of 11. There must be a mistake somewhere.

from the school. All the best!
