The hiring of firefighter or paramedics is under the authority of the Oak Brook Board of Fire and Police Commissioners and is done by competitive examination. Upon completion of the examination process, successful candidates are ranked by score on an eligibility list in descending order by score. The Fire Department will then seek candidates from the eligibility list when vacancies occur. The eligibility list, once posted, is current for two years. The current eligibility list will expire January 5, 2016. Approximately four months prior to the expiration date of the eligibility list, the Board of Police and Fire Commissioners will begin the examination process to establish a new eligibility list.
