The assessment of inmate risk and need in prison poses a unique challenge to correctional policy makers because it is used for two purposes: classification and case management. Classification and case management require assessment instruments that are designed to predict two separate outcomes: institutional misconduct and community recidivism. The current research examines differences between a prison classification instrument developed to predict misconduct and a case management instrument developed to predict community recidivism using a sample of 414 inmates in Ohio. The results indicated substantial differences between assessment instruments and that separate risk and needs assessments should be conducted. A hybrid assessment system is suggested that seeks to maximize accuracy and efficiency by including select factors from each instrument.
