Purpose Statement

To protect society from unwarranted acts, both now and in the future, which may be committed by offenders who have been referred to us for the purpose of rehabilitation. The primary way we can fulfill that responsibility, as far as the future is concerned, is through a program of "productive adjustment."

Institution Information

A new medium-security prison was first proposed in 1977, by the "Flad Report," a six-year plan commissioned by the Legislature, which designated “…the 300 bed medium security institution shall be the Oshkosh Correctional Institution (OSCI), located north of the city of Oshkosh at the site of the DOC Winnebago Correctional Farm."  Construction was started in the fall of 1984, and OSCI was activated to receive inmates in September of 1986.  In order to make room for the many expansion projects to the institution, the Winnebago State Prison Farm was razed and relocated to Waupun.  


Training Kitchen Information

The OSCI Training Kitchen operates in the institution visiting room; hours of operation vary.  When open, inmates may purchase food items for their approved visitors from a restaurant-style menu.
