Researching WISC-V 

We assembled evidence from a range of sources to support the validity, reliability, and fairness of WISC-V in assessing children’s intellectual ability. 
 
The test-retest reliability coefficient and overall average reliability coefficients above are based on a 2014 study of 2,200 US learners aged 6-16. 
 
The correlations between different forms of the test are based on a study of 651 participants aged 6-16.
