What is the difference between WISC and WIAT?
The WISC is designed to assess intelligence, not school performance. The WIAT is designed to assess academic performance and does not predict intelligence. It can be useful to compare these scores to see if your child is performing academically up to their intelligence.
How do you do ability achievement discrepancy?
First, locate the GAI score in the extreme left or right column, and then read across the row. For each subtest or composite, subtract the student’s predicted score from the observed score to obtain the difference score.
What is the difference between the WAIS and the WISC?
The WAIS-III produced a significantly higher mean Full Scale IQ score than the WISC-IV, in a sample of 16 year olds who attended special school. The difference between the mean Full Scale IQ score on the WAIS-III and the WISC-IV was 11.82 points, with the WAIS-III scoring higher.
Can I still use the WIAT III?
Yes, you can use an existing KTEA-3 or WIAT-III administration with the new Dyslexia Index score manual.

Divergent WISC-IV profiles were observed despite no significant intelligence quotient difference between groups. Autistic children scored significantly higher on the Perceptual Reasoning Index than on the Verbal Comprehension Index, a discrepancy that nearly tripled in comparison to WISC-III results.
How do I conduct a PSW discrepancy analysis with the WIAT-III?
However, you can conduct a Pattern of Strengths and Weaknesses (PSW) discrepancy analysis with the WIAT-III alone or by creating a combination report with a compatible ability test. Using the WIAT–III Scoring Assistant only, a PSW analysis can be calculating by manually entering scores from the WPPSI–III, WISC–IV, WAIS–IV, DAS–II, or the KABC–II.
What is the difference between the WISC and the WIAT?
These exams on the surface may appear to be very similar, but there is a key difference. The WISC is designed to assess intelligence, not school performance. The WIAT is designed to assess academic performance and does not predict intelligence.
