The aims of the instructional program should be considered within the context of the proposed mission for the school as a whole. Consistent with the legislative mandate and planning committee recommendations noted above, a problem-focused, interdisciplinary program of research, education, and public service has been established. The program is problem-focused, since the school addresses issues confronting the entire criminal justice system, from the nature of delinquency and crime to society's varied responses to it, including the organization and operation of component criminal justice agencies such as the police, the judiciary, and corrections. The school is interdisciplinary in structure, since no traditional discipline covers the wide spectrum of expertise required. It is a major national and international center for scholarly research on all aspects of delinquency, crime, and criminal justice administration, adding to knowledge, providing a basis for the educational programs, and meeting its public service obligations in part by addressing the major need of all criminal justice agencies for improved procedures of evaluation and planning. Within this setting, the school provides graduate programs of instruction and research to prepare students for positions in research, teaching, and criminal justice system management and policy making.
