Although recognized as a highly effective subject-acceleration intervention, accessibility of Advanced Placement (AP) coursework is not equally available to all students. This lack of access may contribute to documented disparities in AP participation between rural schools and their urban and suburban counterparts. The current study explores the effect of an online AP program on AP participation and exam-passing rates, in a single Midwestern state with a sizable rural population. Study results show that increased availability of AP coursework in rural schools increased access to AP in small to middle sized schools; however, the increased availability did not translate into increased AP exam participation. Nevertheless, exam-passing rates for those who took the exam was higher for schools that participated in the online program. Recommendations for building pathways to academic acceleration and achievement for rural students are discussed.
