What is the average range on the WISC-V?
90 to 109

What is the average IQ score on the WAIS IV?
100
On the WAIS, Wechsler instead compared scores of the test-taker to those of others in his or her general age group. The average score is fixed at 100, with approximately two-thirds of all scores falling somewhere between 85 and 115.
What do WISC III scores mean?
The WISC-III yields three IQs, a Verbal Scale IQ, a Performance Scale IQ, and a Full Scale IQ. All three are standard scores (mean of 100 and standard deviation of 15) obtained by comparing an individual’s score with those earned by the representative sample of age peers.
What is a normal standard score?
It is also known as a standard score, because it allows comparison of scores on different kinds of variables by standardizing the distribution. A standard normal distribution (SND) is a normally shaped distribution with a mean of 0 and a standard deviation (SD) of 1 (see Fig. 1).
What is a composite score Wisc?
A Composite Score that represents a child’s overall intellectual ability (FSIQ) Primary Index Scores that measure the following areas of cognitive functioning: Verbal Comprehension Index (VCI), Visual Spatial Index (VSI), Fluid Reasoning Index (FRI), Working Memory Index (WMI), and the Processing Speed Index (PSI).
What is the highest IQ score on the WAIS IV?
One Full Scale IQ (FSIQ) is also calculated. These scores range from the lowest (40) to the highest (160) points. Subtests are given for additional examination of processing abilities.

The mean FSIQ scores are almost identical. The corrected correlations between the composite scores of the two versions range from .83 to .90. In addition, 68\% and 81\% of the WISC–IV FSIQ scores are within the 95\% and 99\% confidence interval of the WISC–III FSIQ scores, respectively.
