Public Information Officers (PIOs) are the communications coordinators or spokespersons of governmental organizations (i.e. city, county, school district, state government and police/fire departments).
The primary responsibility of a PIO is to provide information to the media and public as required by law and according to the standards of their profession. Information management is the most important responsibility of all public information officers or PIOs.
The Federal Emergency Management Agency uses PIOs to keep the public updated on disaster situations, damage reports and relief efforts. A PIO in a government agency handles emergency communications through the Incident Command System, or ICS.
