Large Discrepancies On The WASI II Scores
By Inderbir Kaur Sandhu, Ph.D
Q: My daughter took the WASI-II for
admission to her school's gifted program, and her scores varied so
greatly that I'm wondering whether I should have her tested for an LD.
Her %ile scores were the following:
99.9% for vocab
91% for similarities
75% for matrix reasoning
9% for block design
Her composite scores were the following:
What might these huge variations point to? Non-Verbal Learning Disability? Also, what kind
of additional testing, if any, would you recommend? Thank you.
There is indeed a gap between the verbal and perceptual reasoning
scores. On the WASI II, the Block Design subtest is designed to measure
the ability to analyse and synthesize abstract visual stimuli.
Vocabulary is designed to measure an examinee's word knowledge and
verbal concept formation. Matrix Reasoning taps on fluid intelligence,
broad visual intelligence, classification and spatial ability, knowledge
of part-whole relationships, simultaneous processing, and perceptual
organization. The Similarities subtest is designed to measure verbal
concept formation and reasoning. Finally, Perceptual reasoning is a
person's ability to visualize, understand, and work with non-verbal
Her verbal scores are in the very superior range and perceptual
reasoning is in the average range. Her FSIQ appears to be in the high
average. There is definitely a huge gap between her verbal and
It appears that your daughter scores very low on block design which may
be indicative of any of the following: poor perceptual skills; poor
visual motor coordination; inability to deal with abstract; deficient
non-verbal reasoning; visual problems; inattention; possible cerebral
dysfunction; anxiety; depression; visual motor coordination;
figure-ground disorder; visual input disorder.
Without further testing, it is hard to determine if she has NVLD (Non-Verbal Learning Disability).
It is best to get her further tested to rule out any disorder that is causing
her to have trouble with her perceptual skills. A variety of evaluation
procedures are used to determine NVLD. There is no single list of tests
for NVLD since the evaluation procedures are individualized.
Please see a clinical psychologist to decide what would be best for your
daughter. Here's wishing you all the best in your journey.
