Jewish Big Brother and Big Sister Associations affiliate with JSSB. Big Sisters are given course instruction by the agency director and are required to complete a period of training in field work before any assignment are made. One of the benefits of this affiliation is that it provides a “continuous supply of newly trained volunteer workers, who are not only valuable in a supplementary manner in the case work of the agency, but are aides in interpreting accurately the work of the family agency and social work efforts, in general, to the community,” according to the Jewish Federation.
