Large Discrepancy Between Verbal And Performance Scores in WASI
By Inderbir Kaur Sandhu, Ph.D
Q: What does it mean when the verbal score is 25 points higher than the performance score on the WASI? (Verbal was 144, Performance was 119) Is this usual?
A: Based on your scores, it appears that you have Superior verbal IQ and High Average for performance. However, the gap is rather large (and not common) and this could indicate a specific learning disability that is nonverbal learning disorder (NVLD). If one has difficulties with fine motor skills, this could happen as well.
However, this is not sufficient to firmly conclude an NVLD diagnosis, in the absence of all the other factor. A more comprehensive evaluation is necessary (neuropsychology assessment).
Wechsler Abbreviated Scale of Intelligence (WASI) is a quick measure of intelligence in clinical, educational, and research settings that yields Verbal, Performance, Full Scale IQ scores. It gives a quick estimate of scores but not sufficient for an in-depth analysis. You may want to consider the WISC-IV or WISC-V for a more comprehensive evaluation of intelligence.
In any case, the scores above shows above average ability for both areas. It is advisable that you see the examiner for further interpretation. WASI Anyone except the examiner cannot draw concrete conclusions, but may only raise suspicions for further investigation.
