The Westchester County Department of Human Resources administers the civil service examinations for Correction Officer, Police Officer, Police Officer (Spanish Speaking), and Firefighter.

The eligible list resulting from the Correction Officer examination is used for the Westchester County Department of Correction. The Police Officer and Firefighter eligible lists will be used to fill vacancies in the Westchester County Department of Public Safety Services (Police only), and the Police and Fire Departments of the cities of Peekskill and Rye, and all the towns and villages within the county.

The cities of Mount Vernon, New Rochelle, White Plains and Yonkers are separate civil service agencies, and administer their own examinations independent of Westchester County.
