This is the second advanced level in the Social Worker series. Incumbents at this level are expected to have an understanding of social services theory and practice that has been gained through either a bachelor's level education combined with four years of work experience or completion of a qualifying master's degree program. Positions are assigned to Child Protective Services or Adult Services, or may provide program oversight in other areas.

The Social Worker IV is also distinguished from the Social Worker V class in that a Social Worker V is the most advanced level in the series and incumbents must possess a master's degree and one year of post-master's to perform social casework with more independent judgment and authority than a Social Worker IV.
