Imprisonment has long been considered as a righteous response of the society and the best warning for offenders to stop doing criminal acts. It is also considered to be one of the most effective ways to combat crime. The purpose of prisons today is the rehabilitation of offenders in order to change their behavior and attitudes, so that they are free to live according to laws and social norms. Prison release and community reentry represents a big shock for a person, especially when it comes to long prison sentences. Adjusting back into the community isn't an easy task. Therefore, an important role in preparing inmates for prison release has the penal institution, in which the inmate was imprisoned, in collaboration with other institutions. The probation system has a big role in cooperation with prisons and penitentiaries, the system of social welfare, civil society organizations and local community during the offender's community reentry. It is necessary to encourage high-quality multi-sector collaboration between different systems and institutions in order to help ex- prisioner with their community reentry and to counter all the negative influences that can affect them to re-commit crimes. Preparation for prison release and prison aftercare are determined by the laws, but there is still a lot of effort needed to make the entire process of preparing inmates for prison release and community reentry to function properly.
