Rooted in sociological models of educational transitions and tracking, this study examines patterns of stratification in the educational trajectories of low- and high-socioeconomic (SES) students. Utilizing longitudinal data from the Educational Longitudinal Study of 2002, this study describes differences in students' choice sets based on a number of metrics obtained from the Integrated Postsecondary Data System (IPEDS). Additionally, multinomial logistic regression models are used to demonstrate the relative probabilities of attending a low-, moderate-, or high- selectivity undergraduate institution between students of low- and high-socioeconomic statuses. Overall, the results demonstrate the pervasiveness of inequality in the college choice decisions of low- and high-SES students and the continued stratification of opportunity for students based on their family background. The study concludes with implications for policymakers and practitioners working within secondary and postsecondary educational sectors. (Contains 5 tables and 10 notes.)
