This memorandum provides information on Advanced Placement (AP) and International Baccalaureate (IB) course enrollment, exam participation, and exam performance during the 2021-2022 school year in Montgomery County Public Schools (MCPS). The College Board shifted their testing procedures in 2019-2021 due to the COVID-19 pandemic. During the pandemic, emergency remote learning, problems with access to technology, and reductions in course load for some students may have had unintended consequences on students' enrollment in AP/IB courses and participation in exams. Students returned to in-person testing in 2021-2022 school year because schools were open. In 2022, all 25 comprehensive high schools offered AP courses, and eight offered IB programs. From 2020 to 2022, the AP/IB course enrollment rate decreased by 9.3%. The enrollment rate decreased by 5.2% from 2021 to 2022. Some equity gaps expanded during and in the wake of emergency remote learning due to the pandemic. The number of AP exams taken by high school students was 33,291 in 2022, a decrease of 5,963 tests from 2020 but an increase of 1,541 tests from 2021. The percent of AP exams taken by students with a score of 3 or higher was 72.4 in 2022, a 2.7 percentage-point decrease from 75.1 in 2020 but a 4.3 percentage-point increase from 68.1 in 2021. Participation in IB exams decreased from 3,688 in 2020 to 3,084 in 2021 and 2,992 in 2022. The percentage of IB exams taken by students with a score of 4 or higher was 82.5% in 2022, an increase of 1.4% from 81.1% in 2020 but a decrease of 4.5% from 87% in 2021.
