The Equal Opportunity Schools (EOS) Initiative: Examination of Changes in Participation and Success in AP/IB Courses


In July 2016, MCPS entered into a partnership with EOS to create greater access to and success in Advanced Placement (AP) and International Baccalaureate (IB) courses, especially for underrepresented student groups. This study examined: 1) trends in participation and success of students receiving Free and Reduced-price Meals System (FARMS) services and Black or African American and Hispanic/Latino students in AP/IB courses following the implementation of the Equal Opportunity Schools (EOS) initiative in MCPS schools, 2) the progress toward attainment of school-level equity for enrollment and performance in AP/IB among participating schools, and 3)  student performance (as measured by GPA and college and career readiness measures) for schools implementing EOS and schools without EOS during school years (SY) 2016 to 2019.


  • Explore factors associated with progress toward, as well as barriers to, increasing participation and success in AP/IB courses by traditionally underrepresented students.
  • Examine whether the timing or sequencing of AP/IB courses is associated with rates of participation and success in AP/IB.
  • Examine reasons for the discrepancy of students earning a C or above in course grades and not earning a college-ready score in the AP exams.
