Annual funds face pressures to contact all alumni to maximize participation, but these efforts are costly. This paper uses a logistic regression model to predict likely donors among alumni from the College of Arts & Humanities at the University of Maryland, College Park. Alumni were grouped according to their predicted probability of donating and then solicited for contributions during the current year's Annual Fund drive. Differences in donation rates between likely and unlikely donors were not statistically significant. Possible reasons for this null result are discussed.
