Idaho Department of Correction's mission is to Protect Idaho through Safety, Accountability, Partnerships and Opportunities for Offender Change. IDOC is responsible for the incarceration and community supervision of felony offenders in Idaho. The department operates eight prisons, four community work centers and probation and parole offices in seven districts. The Contract Facility Monitoring department provides oversight and monitoring of the contracts between the state of Idaho, county jails and two privately-operated prisons south of Boise, the Idaho Correctional Center and the Correctional Alternative Placement Program. At the end of 2010, there were a total of 7431 incarcerated offenders in Idaho prisons.
Incarcerated offenders include termers and riders. Termers are offenders sentenced to a term of incarceration by the courts. Offenders can also be committed to term by the Commission of Pardons and Parole upon parole revocation.
