SECTION 60.09 Certification
   When a requisition is received, certification will be made in accordance with established priorities. In using established eligible lists, certification of the persons standing highest on the appropriate eligible list shall be initiated. The Secretary of the Commission may provide an additional name or names as required to meet the minimum requirements of the certification formula. This procedure may be necessary if individuals originally certified are no longer interested in employment, fail to appear for an interview, decline appointment or are otherwise not available.
   The number to be certified for positions shall be determined by providing three (3) names for each vacancy.
   Every person who is certified but not appointed must be considered on four (4) different certifications for permanent appointment. Candidates certified from a promotion-by-nomination list shall be interviewed wherever practicable and deemed necessary.
   A certification shall not be charged against persons who are within appointing range when the certification is issued to fill a position currently held by a provisional employee who has completed the prescribed probationary period and is within appointing range on the eligibility list.
   In all cases, certification shall be made without regard to sex, race, color or creed, except whenever "sex" is specified in a requisition with specific reasons therefor. The Commission may, at its discretion, certify only those of the sex so specified. Selective certification may be made from an eligible list by the Civil Service Commission for reasons of business necessity relating to candidate preferences, eligibility based on funding sources and requirements, specific job requirements, shift work and other reasons as determined by the Civil Service Commission.
   If there are fewer than three (3) names remaining on an appropriate eligible list, these names will be certified and the Appointing Authority may select one, or he may reject the list and a provisional appointment may be made as hereinafter provided.
   In case there is no eligible list for the class of positions for which certification is requested, or if fewer than three (3) names appear on such list, the Commission may direct the certification of names from eligible lists most nearly appropriate to the positions to be filled or order a new eligibility list to be established.
   In case an eligible person's name appears on more than one list, appointment to a position in one class may be considered a waiver for appointment from other eligibility lists for classes the salary of which is equal or lower.
