Standardized assessments of risk and need are important improvements in juvenile justice (Hoge 2001). They have the potential to improve decisions that affect both the juvniles involved and the use of system resources (Hose 2001). For these improvements to be made, it is essential to examine the instruments used to produce these assessments in terms of their reliability and validity. This paper examines the internal reliability of the YSL/CMI scores of approximately 1000 juveniles assessed in Nebraska. In addition to these analyses, we also examine the distribution of the resulting scores and collateral information concerning the results of other assessment outcomes and the system response to these juveniles.
