The sample included 1,341 persons (1,268 men and 73 women). Each case was followed until termination from the adult field caseload, or until 1 year elapsed from the date of release, whichever came first. Individual case-based data from the division of corrections (DOC) computerized information systems were used. The Uniform Parole Report (UPR) classifications of parole outcome were used as the basis for collecting the data. Parole outcomes during a 1-year followup period for persons released to parole during the period from 1974 through 1978 were analyzed. The findings showed that the parole success rate for males increased steadily over the 5-year period, with the exception of 1976. The success rate in 1978 was higher than any of the previous 4 years. Males classified as successful comprised 74.2 percent of male releases to parole in 1974, 78.9 percent in 1975, 75.5 percent in 1976, 81.1 percent in 1977, and 86.1 percent in 1978. The percent of females with a successful outcome averaged 89 percent over the 5-year period. Violations reported during the 1-year followup period were more serious for males than for females. For males, a total of 10.4 percent were revoked, and of these, 4.6 percent were for a new major conviction. For females, 4.1 percent were revoked. The relationship between the population characteristics of the 1978 release sample and parole outcomes and statistical data are included. Tables are supplied. A list of parole outcome definitions and of offense categories is appended.
