The two centers, one for youths aged 14 to 16 and one for youths aged 17 to 20 contrasted with the previous approach, in which deprivation of liberty was regarded as the punishment, and positive training, particularly of an educational nature, was emphasized. The new regimes included increased emphasis on a more sustained pace in carrying out tasks; hard physical work; more physical education; fewer privileges; less association; an earlier time for lights out; and an increase in the number of parades, inspections, and drill sessions. In September 1981, similar regimes were introduced at two additional centers. An April 1982 report by the Prison Officers' Association concluded that the experimental regime does not have the confidence of prison officers. It noted an actual reduction in the emphasis on work, frustration for trainees, boredom and demoralization resulting from the added drill training, and a lowering of staff morale. A May 1983 report from the Chief Inspector of Prisons noted the lack of flexibility for responding to individual needs and loss of staff morale. Data on reconviction rates for those experiencing the new approach have not yet been reported.
