57 - Continuous recruitment for certain positions.

§ 57. Continuous  recruitment  for certain positions.  Notwithstanding  any other provisions of this chapter or any other law, the civil service  department or a municipal commission may establish a continuing eligible  list for any class of positions for which it finds inadequate numbers of  well qualified persons available for recruitment.   Names  of  eligibles  shall  be  inserted  in  such  list  from time to time as applicants are  tested and found qualified in examinations held at such intervals as may  be prescribed by the civil service department  or  municipal  commission  having  jurisdiction.  Such  successive  examinations  shall,  so far as  practicable, be constructed and rated so as to be  equivalent  tests  of  the  merit  and  fitness  of  candidates.  The name of any candidate who  passes any such examination and who  is  otherwise  qualified  shall  be  placed  on the continuing eligible list in the rank corresponding to his  final  rating  on  such  examination.  The  period  of  eligibility   of  successful  candidates  for  certification  and  appointment  from  such  continuing eligible list, as a result of any such examination, shall  be  fixed  by  the  civil  service  department  or municipal commission but,  except as a list may reach an announced terminal date, such period shall  not be less than one year; nor shall such period of  eligibility  exceed  four  years.  Subject  to  such  conditions and limitations as the civil  service department or municipal commission may  prescribe,  a  candidate  may take more than one such examination; provided, however, that no such  candidate  shall  be certified simultaneously with more than one rank on  the continuing eligible list. With respect to any candidate who  applies  for  and  is  granted  additional  credit  in  any such examination as a  disabled or  non-disabled  veteran,  and  for  the  limited  purpose  of  granting such additional credit, the eligible list shall be deemed to be  established on the date on which his name is added thereto.
