The chapter first examines the application of new hard technologies in community corrections by addressing the design, development, and implementation of electronic monitoring (EM) programs in a variety of community corrections settings, including probation, parole, and day-reporting centers operated out of county jails. The authors review the empirical evidence on the impact of EM systems on the community control of offenders. This is followed by descriptions and assessments of drug-testing technology. Topics discussed are the types/methods of drug testing, the extent of drug testing in community corrections, the effectiveness of drug tests, and drug-testing issues and controversies. The chapter then addresses technologies for managing alcohol-involved offenders. The technology, extent of use, and effectiveness are discussed for ignition interlock devices and remote monitoring systems for offender alcohol consumption. A section on the technology, extent of use, and effectiveness of devices for managing sex offenders focuses on polygraph testing, the penile plethysmograph, and the management and monitoring of sex offenders' computer use. Automated reporting systems and devices for language translation are also examined. 92 references
