Public Information Officers (PIOs) are the communications coordinators or spokespersons of certain governmental organizations (i.e. city, county, school district, state government and police/fire departments). They differ from public relations departments of private organizations in that marketing plays a more limited role. 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. Many PIOs are former journalists, bringing unique and relevant experience to the position. During crises and emergencies, PIOs are often identified by wearing helmets or vests with the letters "PIO" on them.
Among the oldest and largest public information professional organizations is The California Association of Public Information Officials or CAPIO.
