1. Vacancies in the classified departmental service, unless among the
places excepted from examination, if not filled by either promotion or
transfer, shall be filled in the following manner:
(_a_) The appointing officer shall, in form and manner to be
prescribed by the Commission, request the certification to him of the
names of either males or females eligible to a certain place then
vacant.
(_b_) If fitness for the place to be filled is tested by
competitive examination, the Commission shall certify the names of three
males or three females, these names to be those of the eligibles who,
standing higher in grade than any other three eligibles of the same sex
on the list of eligibles from which certification is to be made, have
not been certified three times to the officer making the requisition:
_Provided_, That if upon any register from which certification is
to be made there are the names of eligibles who have, under section 1754
of the Revised Statutes, claim of preference in civil appointments, the
names of such eligibles shall be certified before the names of other
eligibles higher in grade. The Commission shall make regulations that
will secure to each of such preference-claiming eligibles, in the order
of his grade among other preference claimants, an opportunity to have
his claim of preference considered and determined by the appointing
officer.
2. Certifications hereunder shall be made in such manner as to maintain
as nearly as possible the apportionment of appointments among the
several States and the Territories and the District of Columbia, as
required by law.
3. If the three names certified are those of persons eligible on the
copyist or the clerk register, the appointing officer shall select one,
and one only, and shall notify the person whose name has been selected
that he has been designated for appointment: _Provided_ That, for
the purpose of maintaining the apportionment of appointments referred to
in clause 2 of this rule, the Commission may authorize the appointing
officer to select more than one of the three names certified.
When certification is made from a supplementary or a special register,
and there are more vacancies than one to be filled, the appointing
officer may select from the three names certified more than one.
4. The Commission may certify from the clerk register for appointment to
a place the salary of which is less than $1,000 per annum any eligible
on said register who has given written notice that he will accept such a
place.
5. When a person designated for appointment shall have reported in
person to the appointing officer, he shall be appointed for a
probational period of six months, at the end of which period, if his
conduct and capacity be satisfactory to the appointing officer, he shall
receive absolute appointment; but if his conduct and capacity be not
satisfactory to said officer he shall be notified that he will not
receive absolute appointment, and this notification shall discharge him
from the service. The appointing officer shall require the heads of
bureaus or divisions under whom probationers are serving to keep a
record and to make report of the punctuality, industry, habits, ability,
and aptitude of each probationer.
6. All persons appointed to or promoted in the classified departmental
service shall be assigned to the duties of the class or place to which
they have been appointed or promoted, unless the interests of the
service require their assignment to other duties; and when such
assignment is made the fact shall be reported to the head of the
Department.
