The test can be of particular value to school psychologists screening for specific learning disabilities because of the number of specific subtests that make up each section.
It consists of 16 subtests, not all of which are used for every age group.
These areas are covered by ten subtests that include activities measuring both verbal and non-verbal intelligence.
The results of these tests, along with the subject's age, determines the number and level of subtests to be administered.
Total testing time is around 45 to 60 minutes, depending on the child's age and the number of subtests given.
