The study sites all set out to engage a large share of TANF recipients in program activities, but they did so using different approaches. For instance, one site requires only some TANF recipients to participate in program activities, but those activities must be related to work. Another site requires all TANF recipients to participate in case management, but only some to participate in work activities. And although five sites require virtually all recipients to participate in work activities, the philosophies guiding the programs and the contexts in which they operate differ. This chapter discusses each site's philosophy and general approach to engagement as well as the key TANF policies and program features that put the approaches into practice. Additional information on site-specific policies and program features appears in Appendix A.
