WISC-IV Score Interpretation
By Inderbir Kaur Sandhu, Ph.D
Q: My son Wechsler intelligence scale composite score are as below:
Verbal Comprehension- 104
Perceptual reasoning- 94
Working memory- 102
Processing speed- 131
Full scale- 109
I don't understand what does this mean. Is he a gifted child. If he is, then what I can do to explore all his potential.
A: Based on the overall score (FSIQ), your son scored in the Average range on the WISC-IV. See the classification table below for the description of the scores.

All scores are in the Average range except for his Processing Speed score which is the Very Superior range. Processing speed has to do with how quickly a person is able to carry out simple or automatic cognitive tasks; usually this is measured under time pressure such that a degree of focused attention is involved. Other brain functions such as perception and motivation are also crucial for a person to exhibit good processing speed. Processing speed is one of four psychometric constructs (as tested in the WISC-IV) that are considered important in helping us understand an individual child's learning abilities.
However, he would need an IQ score of about 130 to be placed in a gifted education programme. Speak to the school about his results - doing exceptionally well in Processing Speed but averagely on the others may indicate a learning concern that needs to be given attention to. Wishing him all the best.
