This normative study of the American Association on Mental Deficiency (AAMD) Adaptive Behavior Scale--Public School Version was based on 291 Texas public school children divided into 12 categories. The categories were: age, ethnic, or racial group (white or non-white), and assignment to regular classes or special education classes for the educable mentally retarded, trainable mentally retarded, or learning disabled. Part I of the scale was emphasized in this report; it provides measures of independent functioning, physical development, economic activity, language development, number and time concepts, vocational activity, self-direction, reponsibility, and socialization. Reliability estimates were based on the total group including eight, ten, and twelve-year old children. Item validity analysis was based on the discrimination between regular and special education groups, although it appears that the raters knew the group membership of the children at the time they made the ratings. The norms from this study were found to be similar to the original AAMD norms for this scale. The authors suggest that the construction and validation of a shortened version of the scale would be useful; and that it has potential for screening children for placement in special education classes.
