Beginning in 2006, Maryland has led the nation as the state with the highest percentage of graduates who earned one or more Advanced Placement (AP) exam scores of 3 or higher. Students in the Montgomery County Public Schools (MCPS) Class of 2013 continued to outperform students in the state of Maryland and the nation on AP examinations, based on "The 10th Annual AP Report to the Nation" released by the College Board on February 11, 2014. Particularly noteworthy is the fact that MCPS' graduates significantly contributed to Maryland's first-place national ranking for AP exam performance. MCPS students account for 51.4 percent of all of the 2013 Maryland graduates who earned a 3 or higher on at least one AP exam. In 2013, MCPS minority graduates maintained the high AP exam participation rate compared with their peers in the state and the nation. MCPS also provides the International Baccalaureate (IB) program for students at selected high schools as an option for experiencing college-level coursework and earning college credits in high school. The IB program continues to grow, and MCPS high school students demonstrate a steady increase in taking IB courses and exams. The increased participation of graduates in IB exams had a corresponding increase in the proportion of graduates who earned at least one IB exam score of 4 or higher--from 5.1 percent in 2011 to 6.4 percent in 2013. A similar trend was observed with regard to IB exam participation and performance for all racial/ethnic groups. The tables included in this memorandum provide data on AP and IB exam participation and performance of 2011 to 2013 public school graduates in MCPS, Maryland, and the nation.
