Case management has evolved over the years, both in its theoretical approach and in its roles and functions. The concept of case management became popular in the criminal justice system as a result of the development of rehabilitation as a correctional approach. Since that time, case management has changed and evolved along with the different schools of thought, as impacted by the social attitudes of the times. Research the history and evolution of case management, and write a paper of 4–6 pages that addresses the following: How has case management changed and evolved over time? What were the schools of thought during each period, and what were the significant issues that existed during those times? How have the roles and functions changed over time? How have the changing correctional approaches impacted the roles and functions of case management?
