This study explored the impact of Advanced Placement and honors course enrollment and high school grade point average (GPA) on first-semester college GPA. Data were collected from 131 college freshmen enrolled at a minority-serving institution who graduated from a public school during the previous academic year. A four-step hierarchical multiple regression analysis indicated that family structure, college status, enrollment in one or more Advanced Placement courses, and enrollment in five or more honors courses accounted for a significant amount of variance explained in first-semester college GPA, both individually and in combination. High school GPA intervened in these variables relationships with first-semester college GPA accounting for a significant amount of variance. Based on these findings, opportunities for future research and implications for K-12 schools and colleges are provided.
