(a) For a position in the Department of Corrections and Rehabilitation, there shall be certified to the appointing power the names and addresses of all those eligibles for peace officer and closely allied classes whose scores, at the time of certification, represent the three highest ranks on the employment list for the class in which the position belongs and who have indicated their willingness to accept appointment under the conditions of employment specified. (b) For purposes of ranking, scores of eligibles on employment lists for the classes shall be rounded to the nearest whole percent. A rank consists of one or more eligibles with the same whole percentage score. (c) If fewer than three ranks of persons willing to accept appointment are on the list from which certification is to be made, then additional eligibles shall be certified from the various lists next lower in order of preference until names from three ranks are certified. If there are fewer than three names on those lists, and the appointing power does not choose to appoint from among these, the appointing power may demand certification of three names and examinations shall be conducted until at least three names may be certified. The appointing power shall fill the position by the appointment of one of the persons certified. (d) Where there is more than one employment list or Limited Examination and Appointment Program referral list, the department may, pursuant to applicable law and board rules, provide a single certified list of eligibles that combines the names and addresses of all eligible candidates. (e) The department may, consistent with board rules, provide for certifying more or less than three ranks where the size of the certified group is disproportionate to the number of vacancies. (f) The department may, consistent with board rules, allow for the names of eligibles to be transferred from lists for the same class or comparable classes where names from one list were certified under the rule of three ranks, and names from the other list were certified under the rule of three names.
