UNDERSTANDING YOUR KBIT2 REPORT

The Kaufman Brief Intelligence Test does not pinpoint specific aspects of intelligence, but it does provide an excellent overview of general mental functioning and offers a stable assessment of how each individual compares in overall intelligence with others of about the same age. 

The Verbal Score measures verbal skills by assessing the student’s knowledge of word meanings.  The verbal tasks measure the student’s concept formation, reasoning ability, and range of general information. 

The Nonverbal Score measures the student’s ability to solve novel problems, those that are not specifically taught or trained.  To solve the problems in the nonverbal section, the student needs to perceive the pictures’ various attributes, generate hypotheses about how the pictures go together and test out the hypothesis to arrive at a solution.

OTHER TERMS:

Raw Score:  the number of questions a student gets right

Standard Score:  describes a student’s location on an achievement continuum.  The scale corresponds to typical performances of grade groups on each test at certain times of the year.  They have no built in meaning.  To interpret the SS, the values associated with typical performance in each grade must be used as reference points.  These numbers are used to compute other statistics.

Confidence Interval:  Since this test assesses complex areas of functioning, the scores are necessarily imprecise.  The confidence interval takes into account the standard error of measurement and with 90% confidence, you know that your student’s true score falls somewhere between those intervals.

Percentile Rank:  % of individuals that the student outperformed in his or her age group

Descriptive Category:  conversion of the IQ composite to a descriptive category

Age Equivalent:  the age at which the average person in the population performs the same as the student being assessed

Significance of Difference:  NS indicates that there is no significant difference.  If large discrepancies are found, then the student might benefit from a comprehensive test battery to understand the meaning of abnormal discrepancies.
