The chapter opens with a definition of corrections as 'the power to hold and change individuals identified with this approach of 'preventive' justice given current criticism of it. The next section details, within the limits of the data, how many and what kinds of juveniles are assigned to an array of institutions, from detention centers and jails to training schools, ranches, camps, and halfway houses. Although an overarching rationale for the assignments to various institutions is not evident, there is a degree of parity between offense seriousness and security in some systems. One chapter section traces the process through an institutional correctional program, examining program assignment, discipline, and release as major elements. The chapter then examines the various legal rules fashioned by courts and agencies to limit and control the discretion of officials who manage juvenile institutions. The remedies available to protect juveniles' rights within correctional institutions are then addressed. The access to legal representation is a critical element in making any of the remedies meaningful. (Author summary modified)
