Under limited supervision, a Senior Welfare Investigator participates in investigation activities relating to suspected fraudulent receipt of aid, and assists in the supervision of a unit of investigative and clerical staff; conducts the more sensitive or complex assignments; serves as a resource and provides training to unit staff; relieves the supervisor of minor administrative duties; maintains liaison with local agencies; and performs related work as required.

Distinguishing Characteristics

The Senior Welfare Investigator is the advanced journey level class in the Welfare Investigator series, with primary responsibility for functional oversight/evaluation of unit employees, in addition to performing the full range of fraud investigation duties that include the more sensitive or complex investigations. The Senior Welfare Investigator class is only for use in agencies where the organizational structure and scope of unit responsibility is broad enough to require the additional Senior Welfare Investigator level. Most Interagency Merit System agencies use the Welfare Investigator II level to perform lead work duties, when there is a small number of staff assigned to the investigative function and a senior level is not warranted. There is not an automatic progression from the Welfare Investigator II to the Senior Welfare Investigator level. The Welfare Investigator II differs from the Senior Welfare Investigator in that the responsibilities of the latter are much broader than those of a lead Welfare Investigator II, due to the complexity and organization of the department.
