Ranking Applicants For Hire

  • Applicants may earn 0 - 130 total screening points. Total screening scores are based on the screening points accrued during the observation examination, oral interview/written examination, and for documentation of military service. Applicants are then ranked in order of their screening process, i.e., from highest to lowest. Successful completion of the screening process places an applicant on an eligibility list for hire for up to a period of one year from the last day of the month in which they screen. If an applicant chooses to retake the test within that time, the most current screening score overrides the previously reported score. Each applicant will have the opportunity to identify one or all of the facilities that they would be willing to take a position at if offered in order of preference.

Background Investigations

  • A background investigation is conducted on all applicants selected for hire. This process involves inquiries via the Law Enforcement Agencies Data System (LEADS), which includes a computerized criminal history check, NCIC hot files, and Secretary of State drivers- information checks. Drug tests and employment reference checks are also conducted. A physical and visual screening exam is administered as well. Information gathered during the background investigation phase may be utilized when selecting an applicant for hire.
  • Conflicts of interest subject an applicant-s file to administrative review prior to consideration for hire. The following situations may result in administrative review and a determination of ineligibility for hire.
  • former DOC or DJJ employee
  • prior convictions for other than minor traffic offenses
  • relatives incarcerated within the Department of Corrections
  • relatives employed by the Department of Corrections
  • suitability issues (i.e., inmate visitor lists; job discharges)
