They are hired by private contractors, but the government sets their minimum hiring, training and equipment standards.
START PSO LAW ENFORCEMENT PRACTICE TEST🎯 What are the six basic functions a PSO performs?
The ISC lists six functions: access control, screening, visitor processing, patrol and response, control center operations, and common tasks. Together they cover 84 critical tasks identified by a 2009 FPS job task analysis, and PSO tests and training are built around those tasks.
START PSO ACCESS CONTROL PRACTICE TEST🇺🇸 Do you have to be a US citizen to be a PSO?
For armed contract officers at federal facilities, ISC minimum criteria require you to be a US citizen (by birth or naturalization) or a lawful permanent resident. Contractors and individual agencies can set stricter rules, and state licensing requirements apply on top.
START PSO LEGAL AUTHORITY PRACTICE TEST🎖️ What experience do you need to become a PSO?
ISC criteria ask for one of these: 2 years of military service (Reserves or National Guard count), 2 years combined security and military service, an associate degree or higher in a security or law enforcement field, a completed police basic academy, or 3 years of armed or unarmed security experience.
START PSO PATROL PRACTICE TEST⏱️ How many hours of training does a PSO need?
