Penal welfarism provides a set of rehabilitation measures in legal and judicial decisions about crime. However, in Iran's criminal justice system, welfare changes are being developed in areas other than prisons, but the correction capabilities of these programs are low. Therefore, the main question is, what factor is responsible for the current state of welfare institutions? Using the analytical descriptive method and relying on Bourdieu's views, we argue that the concept of the penal field provides a better analysis of welfare changes by revealing how practices are formed within the structural forces of the field. By revealing the conflicts, the penal field specifies how situations and habitus can lead to changes towards the idea of ​​control and reconfigure themselves once again through correction. Thus penal welfare institutions reproduce the penal field rather than achieving welfare goals.Unraveling the complexities of criminal power is an important task that shows us that we should move towards a more welfarist and human rights-based criminal justice system.
