The Facility Training Program is a program designed to train new Correctional Deputies in the operations of the facility. This program is fourteen weeks long with four phases and is structured to smoothly transition new employees into a solo Correctional Deputy. Most new Deputies will do an additional phase at the North County Detention Facility. The phases are three to five weeks long with different training Deputies on varying shifts. During the first two phases the new employee is trained to become familiar with the facility, post order operations, and policy and procedures. The last two phases are for the new employee to apply what they have learned, and work as a solo Deputy with the training Deputy "shadowing" them. The new employees receive evaluations of their performance daily and at the end of each phase. Upon successful completion of the training program, the new employee graduates and begins working completely solo.

Male Special Core Deputies are Correctional Deputies that are trained to work in the male special module. Inmates in this module are highly sophisticated, demonstrate aggressive behavior, pose a threat to staff and other inmates alike and have proven they are unable to abide by the rules and regulations of the facility. The male special module is a maximum-security area and is designed differently than any other module. This module is staffed with multiple Deputies on each shift. This is due to the number of Deputies needed for safety around certain high-risk inmates. Safety for staff and inmates within this module, as well as the rest of the facility, is top priority.
