Historically, low-income seniors ages 60 and older who qualify for Food Stamp Program (FSP) benefits participate at low rates because they feel it is not worth the effort to apply. To identify effective strategies for raising participation among this population, USDA designed three models, each using different techniques to reduce the barriers that seniors face in FSP participation. The techniques involve reducing the time and effort of applying for benefits, aiding seniors in navigating the application process, and giving seniors the option of receiving commodity packages instead of getting benefits through electronic benefits transfer cards. The models were tested as county demonstrations in six States between 2002 and 2004. This report presents the findings of the in-depth process analysis component of an evaluation of the demonstrations. Each of the demonstrations was examined individually for overall design and implementation.
