Test and Assessment Development Analysis: WAIS-IV

Describe how the test is administered:

The test is presented in various formats, and has several core subsets. In general, the test takes approximately 60 to 90 minutes to complete.

In the author’s own words, “areas of note are that average split-half reliability for the Full Scale IQ (FSIQ) is an extremely high .98” (Groth-Marnat, 2009, p. 126).

Test and Assessment Development Analysis: MMPI-2
