Characteristics and perceptions of participants in the Senior Citizen Tuition Waiver Program at the University of South Florida (USF) were studied, along with factors important to continuation in the program. Questionnaires were mailed to senior citizens (over 60 years old) using the waiver on all four USF campuses during the first two quarters of its implementation, fall 1980 and winter 1981. The general demographic picture of the senior citizen using the tuition waiver at USF is that the majority are married, have a college education, have an income of $15,000 or more, and are fully retired. Of the demographic characteristics, age, sex, and marital status did not make a significant difference in whether a senior returned. The majority of those who had undergraduate and graduate backgrounds did not return. There was a significant difference in the annual income: 53.1 percent of the nonreturnees had an income of $10,000 or more, while only 29.5 percent of the returnees had an income of this amount. Those who did not return worked more often either part- or full-time than those who did return for studies. While self-perception of age varied little between returnees to nonreturnees, the nonreturnees evaluated themselves as higher in physical health, physical activity, mental activity, social activity, and community involvement. This pattern suggests that returning students, as a group, may be more dependent on the educational program for satisfying personal needs, while the nonreturnees have a wider range of outside activities and support. Twice as many of the returnees attended orientation-registration than did nonreturnees. Recommendations concerning publicity and orientation-registration are offered, and a bibliography is appended.
