Interpretation of the K-BIT-2 Scores
By Inderbir Kaur Sandhu, Ph.D
My 5 year old son recently took the KBIT-2 I do not understand his
Verbal was low 114
His school district is requesting a re-test in August ?
What do his scores mean and will it benefit him to retake test? Thanks.
The Kaufman Brief Intelligence Test, Second Edition (K-BIT 2) is used to
measure verbal and nonverbal cognitive ability. It is used to obtain a
quick estimate of intelligence, estimate an individual's verbal versus
nonverbal intelligence and/or to screen to identify students who may
benefit from enrichment or gifted programs. Additionally, this test is
also able to identify high-risk children through large-scale screening
who may require a more comprehensive evaluation. So, briefly, it serves
the purpose to provide a relatively quick and accurate estimate of
abilities; and to identify students who may benefit from gifted or
This test is developed by leading cognitive ability experts Alan and
Nadeen Kaufman, therefore, it is assumed that this test provides highly
valid, reliable results and is useful for a broad range of purposes.
With the test package, a scoring and administrative manual is provided,
so it is quite easy to use the materials. Hence, scores given by the
school is accurate based on the correct use of the scoring manual.
Having said that, the teacher in charge of the test should at least have
good knowledge on the principles of measurement and in the
administration and interpretation of tests.
Note: This test is researched to have a rather high
correlation with the Wechsler tests (Wechsler Abbreviated Scale of
Intelligence -WASI, Wechsler Intelligence Scale for Children - WISC and
the Wechsler Adult Intelligence Scale - WAIS).
Based on a mean of 100 and standard deviation of 15, your son scores
appear to be above the average scores (about 85-115 should be within the
average range on a bell curve) for the K-BIT-2. This means an overall
score of 124 places him in the top 15% of performances. The cut-off for
a gifted education programme is usually 130 (your son scored 124) but
can be on a case by case basis.
What I find somewhat not very comfortable with is the discrepancy
between the verbal and nonverbal scores. This may be the reason for a
re-test. Do speak to someone at his school to find out the reason for a
re-test. Retesting in done when the scores may not indicate the child's
true abilities or there is a discrepancy detected. You may want to check
the discrepancy in his results. His verbal scores definitely brought
down his overall composite score.
Hope the score interpretation is a little clearer to you now. Best of luck!
