How Are KBIT Test Scores Calculated?
Three scores are generated by the KBIT-2 Test:
- Verbal (assesses crystallized ability)
- Nonverbal (assesses fluid reasoning)
- Overall IQ composite
. The Overall IQ (or Composite IQ) score is generally what people are referring to when discussing a person’s IQ. This score is based on the verbal and nonverbal subtests of the KBIT Test. The average IQ score ranges from 90-110. This is the score you will see in your child's test results.
The Overall IQ Score is found by converting the Raw Score (the total number of points earned on each subtest) into a standard score, with a mean of 100 and a standard deviation of 15 (see bell curve below). The range of the Overall IQ Score is between 40 - 160.
The table below provides a general description of what your child's KBIT scores mean:
|130 and above||Upper extreme|
|120 -129||Well above average|
|110 - 119||Above average|
|109 - 90||Average|
|80 - 89||Below average|
|70 - 79||Well below average|
|69 and below||Lower extreme|
