Korean Correctional Service conducted survey on satisfaction level of inmates, correctional officers and visitors about the correctional policies in 2006 and the period between 2011 and 2013. And among the survey results, this study focuses on the satisfaction level of inmate and changes in trend to make useful proposal for the correctional policy. Survey items include treatment, rehabilitation and edification, and education for inmates, which are composed of 10 subcategories. According to the survey results, demands for continued improvement in accommodation atmosphere and medical treatment for inmates are high, while inmates are greatly satisfied with edification and rehabilitation programs. In particular, the results show that video visiting system and family visiting room which are newly operated recently are the most satisfactory and efficient system. In terms of edification and rehabilitation of inmates, demands for rationalized work incentives and vocational training program are the highest. Future correctional policy should focus on the program which may enhance the inmates’ capabilities to adapt the society as a social member. In addition, if the formality of the survey report is supplemented, it could be utilized as the scientific political data. And if the themes of the survey are more systemized and logically categorized and if its sub-categories are decided thereby to provide consistent data on the annual basis, it could make sustainable contributions in the policy-making process.
