The authors used a logit model with partial derivatives to identify which demographic and academic variables are associated with 1st-year attrition and persistence of Hispanic students and to determine the extent to which these factors affect the students' decision to remain or leave the university. The model was able to correctly predict the students' decision to continue or leave the university for 4 of every 5 students participating in a program developed for at-risk students.
