Our research goals are to make the case that parent-student discussions about college planning should be seen as a distinct college-planning activity and to identify and test the relevant predictors of these discussions. Findings from over 4,000 parents and their high school children show that parent-student discussions are enhanced when both the parents and students engage individually in college preparation, have higher college aspirations, and are more involved in the school and community. These activities of parents and students interact significantly to further enhance intergenerational discussions. The findings can inform current models and approaches to college choice as well as policies and programs that strongly emphasize parental involvement. (Contains 3 tables and 1 figure.)
