In this form of community service, people convicted of crimes are required to perform community services or to work for agencies in the sentencing jurisdiction either entirely or partly in lieu of other judicial remedies and sanctions, such as incarceration or fines.
For instance, a fine may be reduced in exchange for a prescribed number of hours of community service. The court may allow the convict to choose their community service, which then must be documented by "credible agencies", such as non-profit organizations, or may mandate a specific service.
Sometimes the sentencing is specifically targeted to the convict's crime, for example, a litterer may have to clean a park or roadside, or a drunk driver might appear before school groups to explain why drunk driving is a crime.
