 By 1945, state public welfare officials came to believe that early foster care or adoption was preferable to institutionalization, so admissions ceased.In 1947, the Minnesota State Public School for Dependent and Neglected Children (SPS) was officially abolished and all its lands, buildings, property, and funds were transferred to the newly established Owatonna State School (OSS), which provided academic and vocational training for individuals with developmental disabilities.The OSS closed in 1970.
