The purpose of this case study was to examine policies and procedures used by high school leaders that positively impact the access and participation of African American students in Advanced Placement courses. The research targeted the chronic and persistent problem of underrepresentation of ethnic minorities in secondary school Advanced Placement programs. The study explored the protocols and policies implemented by building leaders who have documented participation in Advanced Placement programs for African American students. This study focused on Sumter High School (pseudonym), one of 15 high schools within a large urban school district with demonstrated AP success for African American students. The data analysis from the semi-structured interviews conducted with the Advanced Placement program's Assistant Principal and the review of documents and observation notes, yielded three themes that were determined to have clear alignment with the theoretical framework; equity, enlistment, and encouragement. The findings of the research explain how the school takes an inclusionary approach in their recruitment efforts and program criteria which removes the barriers and encourages participation from all.
