Using data from 1,033 freshmen at a public urban university, this study examined the effect of the perceived quality of academic advising on student attrition in a model of the student attrition process. High-quality advising negatively influenced attrition through effects on GPA, satisfaction in the role of a student, the value of a college education for future employment, and intent to leave the university. Low-quality advising was related to greater attrition than was high-quality advising, but, on the other hand, low-quality advising was associated with less attrition than no advising at all. The effect size of the advising variables suggested that a more extensive provision of high-quality advising might be considered as one strategy in a multifaceted institutional effort to reduce freshman attrition.
