This study was designed to assess continuing and potential students' perceptions regarding factors affecting the overall quality of one Osher Lifelong Learning Institute (OLLI) program in the southeastern United States. The study also sought to assess program participants' perceptions of the impact of hypothesized situational, institutional, and dispositional deterrents to program participation. The resulting data indicated that factors such as program location, availability of parking, and variety of course topics and events influenced the attractiveness of the program to both potential and continuing students. The results also indicated that institutional barriers such as course scheduling were among the most influential perceived barriers affecting program participation from continuing students and from potential students.
