Correctional staff training in Hong Kong consists of both orientation and development training. The former aims at preparing new recruits for the job, while the latter focuses on career development. Basic training (1) introduces new staff to the structure, operation, and goals of corrections; (2) helps trainees acquire the technical and operational skills necessary for the effective performance of their duties; (3) helps develop appropriate attitudes; and (4) promotes the growth of professional skills through practical field placements. Inservice training is designed to help staff prepare for advanced career responsibilities. Release under supervision includes probation, which usually includes the specification of conditions to be fulfilled while on probation; the suspension of a prison sentence; and the use of structured aftercare programs following release from prison. A halfway house program is available to help persons treated for drug addiction to achieve reintegration into society. The prisons use industries for vocational training and treatment centers -- which work with drug-dependent offenders -- include several trade activities in their programs. Detention centers, which aim at correcting young offenders, do not have vocational and industrial training, except for what may be acquired in the performance of community projects. Vocational training has the highest priority in the training centers, which aim at preparing young offenders to practice an employable craft or skill. All inmates are classified by a board which determines the security rating of an inmate. Institutions are categorized in accordance with the various security ratings so that placements are appropriate. Classifications are reviewed from periodically throughout a prisoner's sentence. Tables are supplied.
