What type of headcount is performed at each shift change and at least four times a day?

The correct response pertains to the regular headcount, which is a systematic process performed at shift changes and frequently throughout the day within correctional facilities. This type of headcount ensures that all inmates are accounted for, which is critical for maintaining safety and security. Regular headcounts help verify that no inmates are missing and assist in identifying any potential security breaches or emergencies.

In a correctional setting, consistent monitoring is essential for the day-to-day operations and overall management of the facility. This regular accountability not only aids in maintaining order but also ensures that staff adhere to protocols designed to protect both officers and inmates. Other types of headcounts, such as emergency or random headcounts, do not occur as frequently or involve a structured schedule like regular headcounts do, emphasizing the unique importance of the regular type in daily facility operation.
