For a sample of 49 regular class children, test‐retest stability was investigated for domains and subdomains of the AAMD Adaptive Behavior Scale, Public School Version. Satisfactory indices of reliability were obtained for all Part One domains except Vocational Activity ( r =.43), and for all Part One subdomains except two, Care of Clothing and Dressing and Undressing. Part Two, however, evidenced good reliability coefficients for only three of the 11 domains studied. Moreover, there was a tendency for Part Two retest ratings to be lower (less deviant) than original ratings. These findings suggest that Part One scores are stable and therefore potentially useful, but Part Two domains may lack discriminative power and stability when used with regular class children.
