“…Standardized testing is the expected and accepted approach for evaluating intellectual functioning in cases involving claims of mental retardation. Although the American Association on Intellectual and Developmental Disabilities (AAIDD) maintains that “…limitations in adaptive behavior should be established through the use of standardized measures…” (Schalock et al, , p. 43), adaptive functioning measures do not appear to be as widely used as intelligence measures in general clinical practice (Harrison, Kaufman, Hickman, & Kaufman, ; Hutton & Dubes, ; Stinnett, Havey, & Oehler‐Stinnett, ) or in Mental Retardation evaluations for capital cases (Kan, Boccaccini, McGorty, Noland, & Lawson, ; Young, Boccaccini, Conroy, & Lawson, ). For example, Young et al () interviewed 13 Texas psychologists who had performed evaluations of mental retardation in capital cases and found that only seven (54%) reported that they would use a standardized adaptive functioning measure for pre‐trial evaluations and only four (31%) would use a standardized measure when evaluating an inmate on death row.…”
