Students in the Montgomery County (Maryland) Public Schools (MCPS) Class of 2012 continued to outperform Maryland and the nation on Advanced Placement (AP) examinations based on the "AP Report to the Nation" released by the College Board on February 20, 2013. In 2012, 67.3 percent of MCPS graduates took one or more AP exams. A striking percentage of MCPS graduates earned at least one AP exam score of 3 or higher (52.3 percent), which was 22.7 percentage points higher than the rate for public school graduates in Maryland (29.6 percent) and more than twice the rate for public school graduates in the nation (19.5 percent). AP exam performance among Black or African American and Hispanic/Latino graduates in the Class of 2012 was notable districtwide. MCPS also provides the International Baccalaureate (IB) program for students at selected high schools as an option of experiencing college-level coursework and earning college credits in high school. The IB program continues to grow and MCPS high school students show a steady increase in taking IB courses and exams. The rate of MCPS graduates who took one or more IB exams in 2012 increased by 1.2 percentage points from the rate for MCPS 2011 graduates. From 2011 to 2012, the percentage of MCPS graduates who earned at least one IB exam score of 4 or higher increased from 5.1 to 6.1 percent. All racial/ethnic groups made improvements on IB participation and performance between 2011 and 2012. The growth in AP and IB exam results for the MCPS Class of 2012, especially for Hispanic/Latino and Black or African American graduates, may be credited to the district's commitment to provide increasing access to the AP and IB programs, and to raise the level of support for underserved students in AP or IB classrooms. The tables included in this memorandum provide data on AP and IB exam participation and performance of 2010 to 2012 public school graduates in MCPS, Maryland, and the nation.
