What are the four indices of the Wechsler Intelligence Scale?

The reliability and validity of the WAIS-IV is outlined in the Technical and Interpretive Manual [1]). The main reliability figure based on the standardisation sample for Full Scale IQ was 0.98, indicating good internal consistency.
How long does it take to administer the WAIS IV?
Approximately 60 to 90 minutes
A common purpose for the WAIS is for educational planning and placement with older adolescents and adults. The test includes 11 subtests with various types of format. Approximately 60 to 90 minutes is required for completion.
