The study presented here is an investigation and comparison of the relationships between the Advanced Placement Program® (AP®) and dual-enrolled high school courses and college outcomes. Previous research provides evidence that participation in AP, and subsequent success on AP Exams, is positively related to various college outcomes including an increased likelihood of graduating from college and better preparation for the academic rigor of the college classroom. This study aims to contribute to the understanding of the value of advanced course work in high school in preparing students for higher education success by investigating the relationships between participation and performance in AP courses and exams, dual enrollment courses, and regular courses and four different college outcomes including first-year subject-specific GPA, final subject-specific GPA, calendar time to bachelor's degree, and credit hours attempted. Results indicated that higher performance on AP Exams was related to higher college performance in the subject area, as well as fewer credit hours taken to bachelor's degree. Most dual enrollment course grades were at a C or higher, and students taking these courses tended to graduate from college in fewer calendar terms than other groups.
