Early college high schools (ECHSs), which combine high school with the first two years of college, have grown in popularity nationwide. Research suggests ECHS participation has positive impacts on college enrollment and completion, but little is known about how ECHS graduates experience university life. Using a framework of college belonging and in-depth interviews with 32 ECHS alumni at Sunshine University, a Hispanic Serving Institution in Texas, this study asked how ECHS alumni experience belonging and how the university facilitates it. Findings indicate that students navigated a "weird gray zone," where age-stage misalignment and time pressure created unique obstacles to belonging that the university did not adequately address. This study cautions that early academic acceleration may increase cost savings and degree completion at the expense of student development, and offers recommendations for universities to foster belonging for high school graduates who matriculate with large numbers of college credits.
