This study examined the relationship between engaging institutional environments and alumni donor participation rates at 310 colleges and universities. The study found that engaging environments have positive relationships to alumni donor participation rates at Carnegie Baccalaureate institutions, but the relationship is not significant at Masters or Doctoral/Research institutions. Other variables considered in developing a model for the institutional environment included enrollment size, percentage of students who were female, percentage of students who were White, percentage of students who were Pell eligible, institutional selectivity as measured by "Barron's Selectivity Index", and sector (public or private). The level of institutional engagement was based on results from the National Survey of Student Engagement instrument administered in 2005 and 2006 and Voluntary Support of Education Survey data from the same years.
