Stringency of eligibility

In the Table in Appendix A, there is a category for “stringency of eligibility” (people sometimes also refer to this dimension of analysis as “accessibility” of a program). Address the following three questions about this category: a. What does “stringency of eligibility” mean? (Just the basics, no need for long answers) b. What sorts of things (aspects of a program’s design) does stringency of eligibility refer to? c. Why do policy analysts and social workers care about stringency of eligibility?
