In which design do cells form a perimeter around a common area where staff can hear and observe activities?

In this context, the correct design is known as Direct Supervision Design. This approach allows staff to be present in a designated area where they can actively monitor and engage with the activities of the inmates.

In a Direct Supervision Design, the layout is intentionally structured so that staff can easily observe and interact with inmates, fostering a more oversight-friendly environment. This setup typically utilizes an open space where correctional officers are positioned among the inmates, enhancing visibility and the potential for quick response to incidents.

This design is pivotal because it can lead to improved safety and management of inmate behavior. By being close to the inmates, staff can establish better communication and relationships, which often results in a more cooperative atmosphere within the facility.

In contrast, other design types like Remote Design position staff away from the inmates, limiting their direct interaction and oversight capabilities. Similarly, Linear Design results in a more traditional layout that may hinder direct engagement, while Intermittent Design does not create the continuous supervision environment that is fundamental to maintaining safety and order as seen in Direct Supervision Design.
