The report examines uses, advantages, and criteria for selection of behavior rating scales (BRSs) and their use with juvenile offenders, focusing in particular on the Behavior Dimensions Rating Scale (BDRS). Previously normed using a representative sample of behavior disordered and nonhandicapped males and females in grades K-11 (N=1,942), the present study sought validation of the BDRS in correctional education settings using a standardized sample of 641 males residing in 9 regionally diverse state-operated juvenile correctional facilities. The instrument was completed by teachers, and the factor structure of responses from youth correctional facilities was compared with the factor structure of responses in the original BDRS validation using multi-group confirmatory factor analysis. Results indicated that the BDRS is factorially equivalent for subjects in regular educational settings and for juvenile offenders in correctional institutions. Noting that the delivery of appropriate educational services is dependent upon the assessment process, the instrument's potential use by correctional facilities to assess individual educational and behavioral needs, monitor behavioral change, and evaluate program and therapeutic effectiveness is described.
