service employees or to classified service employees of a certain
class or classes by giving credit for experience and demonstrated
efficiency (not to exceed twenty per centum of all marks) in de-
termining the relative fitness for promotion of such employees.

enlisted army and navy nurses engaged in the service of the
United States at a time when the United States was at war with
another nation and who were residents of this State at the time
of their entry into such service, shall be given special credit for
such service in the experience markings of examinations in which
they may compete, which shall be equivalent to not less than
twenty points on a basis of one hundred.

Promotion is a change from one class to another class with a
higher maximum compensation, and vacancies shall be filled by
promotion as far as is consistent with the best interests of the
classified service, in the judgment of the Commissioner.

The Commissioner shall control all examinations and may
designate as special examiners any officers or employees of this
State or any other person not in the service of this State to con-
duct and hold such examinations as the Commissioner may direct
and to make return and report thereof to him. The Commis-
sioner shall have power to review the findings in all such
reports, and may order new examinations, if he deems such ac-
tion desirable. The Commissioner may at any time substitute
any other person in the place of any person so designated and
may himself conduct such examinations without designating
special examiners.
