Students in the Montgomery County Public Schools (MCPS) Class of 2016 continued to outperform students in the state of Maryland on Advanced Placement (AP) examinations based on AP results released by the Maryland State Department of Education and the College Board. The number and percentage of AP exam participation and performance for the State of Maryland and the nation is different from the AP/IB exam results published in prior reports because Western Interstate Commission for Higher Education changed the projected number of high school graduates in the 9th Edition of "Knocking at the College Door." In 2016, 65.5 percent of MCPS graduates took one or more AP exams, a rate that was 16.2 and 29.3 percentage points higher than the rate for public school graduates in Maryland (49.3 percent) and the nation (36.2 percent), respectively (Figure 1). From 2015 to 2016, the AP exam participation rate remained steady for MCPS, Maryland, and national graduates. The attached tables provide additional information for review. In addition to AP programs, 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 IB course and exam participation. Attached tables provide information for reader review.
