Reply to Sánchez Escobedo and Hollingworth: Why the Mexican Norms for the WAIS-III Continue to be Inadequate

Abstract

The discussion in Drs. Sánchez Escobedo and Hollingworth's paper independently confirms virtually all our observations regarding the psychometric and interpretive deficiencies of the Mexican norms for very high-stakes decisions, such as that involved in an Atkins hearing. Test publishers have an ethical obligation to caution potential users against the premature use of a developing assessment that does not yet meet the needed precision and evidence of validity required for very high-stakes decisions.
