Under general supervision, performs specialized clerical, office-technical and/or secretarial work of above-average difficulty and complexity in a variety of office settings throughout the County; and does related or other work as required in accordance with Rule 3, Section 3, of the Civil Service Rules.


This is the specialist-level class in the Office Assistant series. Positions must meet specific criteria for allocation to this class and are not multi-allocated with other levels in the series. Incumbents are expected to apply a moderate amount of initiative and independent judgment to perform a limited range of complex duties utilizing specialized procedures within established policies. The specific duties performed by incumbents may be unique to the work area and, depending upon the assignment, usually require an advanced understanding of specialized and/or technical subject matter. Typical job assignments that fit the class concept include, but are not limited to: clerical work that requires in-depth knowledge, interpretation and explanation of complex program policies and procedures; advanced clerical accounting, specialized billing and/or collections work; clerical/technical/financial case management in areas such as law enforcement, probation, or mental health services; preparation of complex legal documents and coordination of legal-clerical activities in a non-legal office setting; and advanced responsibility for coordinating complex services/activities with outside agencies/providers. Although incumbents may perform some repetitive tasks involving complex clerical processes (i.e., advanced clerical accounting, billing, and collections work), duties are usually program-oriented as opposed to task oriented, requiring an in-depth understanding of the unique programmatic functions of the work area in order to establish the basis for decision-making. Such decisions may require quick action and may have significant financial, legal and/or public relations consequences.

This class differs from Senior Office Assistant because incumbents of the latter perform less difficult/complex clerical, secretarial and/or office technical work of a general (not specialized) nature, utilizing well-established and standardized procedures that do not require the degree of program or process-specific knowledge expected of incumbents in this class.
