Under direction, supervises a unit of employees performing clerical, office technical and/or secretarial tasks; performs complex work within the unit, including duties that may be quasi-administrative/analytical in nature; and does related or other work as required in accordance with Rule 3, Section 3, of the Civil Service Rules.


This is the first full supervisory level in the Office Supervisor series. Positions must meet specific criteria for allocation to this class and are not multi-allocated with other levels in the series. Incumbents in this class usually function as a first-level supervisor over a medium to large-sized unit, applying substantial initiative and independent judgment to their work, which may also include quasi-administrative/analytical duties.

This class differs from the class of Office Technician/Coordinator because the primary role of an incumbent in this class is as a first-level supervisor with limited administrative/technical responsibilities, while an Office Technician/Coordinator performs broader office management duties that require advanced knowledge of multiple specialized programs or functions. This class differs from that of Office Secretary, because the primary role of incumbents in that class is to provide secretarial support for management and supervision of staff is generally an incidental duty. This class differs from the class of Senior Administrative Supervisor because incumbents in that class usually perform second-level supervision as well as highly advanced quasi-administrative/analytical duties.
