See other key findings from the report, such as school course titles often overstated course content and challenge and graduates in rigorous algebra I and geometry courses scored higher on NAEP.

- In algebra I courses taken by high school graduates, about 65 percent of the material covered, on average, was devoted to algebra topics (
**figure 1**). About 35 percent of the material focused on elementary and middle school mathematics, geometry, and other high school mathematics topics typically taught in later mathematics courses.

- About 17 percent of the course content of graduates' beginner algebra I courses focused on elementary and middle school mathematics topics, compared to 10 percent for graduates who took rigorous algebra I courses (
**figure 2).** - For graduates who took rigorous algebra I courses about 16 percent of the course content was other high school mathematics topics that are generally taught in higher-level courses, compared to 6 percent for graduates in beginner algebra I courses.

- On average, about 66 percent of the material covered in geometry courses taken by high school graduates focused on geometry topics (
**figure 3**). About 34 percent covered elementary and middle school mathematics, algebra, and other high school mathematics topics.

- About 14 percent of the course content of graduates’ beginner geometry courses covered elementary and middle school topics, compared to 11 percent for graduates who took rigorous geometry courses (
**figure 4**). - For graduates who took rigorous geometry courses, 8 percent of their course content was other high school mathematics topics that are generally taught in higher level courses, compared to 11 percent for graduates who took beginner geometry courses.
