Community Service Officers (CSO) perform security functions for student housing, and complete a 8 week field training program specific to the University of Nebraska Lincoln so they can better serve the campus community as first responders. CSO's are an important component in the security of the campus as they serve as additional eyes and ears to police officers. Although Residence hall are the main priority, students will also see them occasionally in academic buildings, computer labs and at sporting events. Daily attire for the Community Service Officer is a uniform consisting of a gray shirt and black trousers.
