Final answer:
The security level at federal institutions with dormitory housing, a low staff-to-inmate ratio, and limited or no perimeter fencing is minimum security or low-security level.
Step-by-step explanation:
The security level at federal institutions that feature dormitory housing, a relatively low staff-to-inmate ratio, and limited or no perimeter fencing is classified as minimum security or low-security level.
In these types of correctional facilities, inmates are often housed in dormitories rather than individual cells. The staff-to-inmate ratio is lower compared to higher-security prisons, allowing for more interpersonal interaction and supervision. The absence or limited presence of perimeter fencing indicates a lower level of physical security.
However, it is important to note that even in minimum security prisons, there are still strict rules and regulations in place to ensure the safety and security of the inmates, staff, and the broader community.
