Average score is higher than U.S. average score at the .05 level of statistical significance.

Average score is lower than U.S. average score at the .05 level of statistical significance.

NOTE: Standard error is abbreviated as s.e. Students taking the TIMSS Advanced physics assessment were categorized based on whether or not they took an AP physics course and the level of AP course they took. Students were categorized based on the highest level physics course taken. The category took an AP Physics C course included students who took mechanics, electricity and magnetism, and combined courses as their highest physics course. The category took an AP Physics B, 2, or 1 course included: (1) students who took Physics B before or during the 2013-14 school year and never took an AP Physics C course; and (2) students who took one or both of two one-year courses designed to replace Physics B after the 2013-14 school year and never took an AP Physics C course. The category did not take an AP Physics course included students who took other courses such as regular or honors second-year physics or International Baccalaureate (IB) physics courses as their highest physics course.
