Early College High Schools (ECs) are growing in popularity as an affordable avenue for students to obtain up to an associate's degree while in high school in Texas. Using Merton's (1966) Anticipatory Socialization Theory, this study investigated how ECs shaped 13 graduates' social behaviors and norms while in high school, and then how they leveraged those behaviors in their transition to college. Results indicate that while ECs proved to be a supportive environment with nurturing teachers, these programs deemphasized social activities, leading to varying preparation of the social skills necessary for college fully. Recommendations for practice and future research are provided.
