This Study Snapshot highlights key findings from a study that seeks to provide Arizona policymakers with national evidence about the education and career planning elements associated with students' college-going behaviors. This correlational study used nationally representative data from the High School Longitudinal Study of 2009 to examine the relationships between students' participation in three education and career planning activities during high school and their application, course-taking, and enrollment behaviors associated with the transition to college. The study explored the extent to which students' self-reported participation in these activities predicted whether they submitted the Free Application for Federal Student Aid (FAFSA), completed a college preparatory curriculum, applied to college, and enrolled in college. In addition, the analyses described the prevalence of education and career planning as a school requirement and a student experience during the study period. [For the full report, see ED615855.
