Standard errors are in parentheses. The reference category for college enrollment is no attendance. College enrollment is conditional on high school completion. All models also include main effects for age, sex, number of children under age 18 in the household, 1997 parental education, 1997 household poverty ratio, and 1997 parental marital status. Models 1–3 include adolescents of all ages, and Models 4–5 include only the older adolescents who answered the educational expectations questions. Probabilities in Models 1–3 come from estimates that are adjusted for individual and family characteristics but not educational participation or performance. Model 2 adjusts for educational participation, Model 3 adjusts for educational performance, and Model 5 adjusts for educational expectations. In all columns, the model is a binary logistic regression model.
