In 2018, the average U.S. history scores for eighth-grade students were 6 points lower in the Culture theme and 4 points lower in the Democracy, Technology, and World Role themes compared to 2014.
However, in comparison to 1994, the average U.S. history scores for eighth-grade students were 9 points higher in the Democracy theme, and 8 points higher in the World Role theme. The average score for the Technology theme was 2 points lower and the score for the Culture theme was not statistically different compared to 1994.
In addition to the overall composite average score, NAEP U.S. history results are also reported for the subscale average scores by the four historical themes: Change and Continuity in American Democracy (Democracy), the Gathering and Interactions of Peoples, Cultures, and Ideas (Culture), Economic and Technological Changes (Technology), and The Changing Role of America in the World (World Role). The NAEP U.S. history framework provides the basis for constructing subscales in U.S. history. The subscales are combined into a composite scale used to describe the overall attainment of students in U.S. history. Because subscales were developed separately for each theme, comparisons cannot be made from one subscale to another. Learn more about what the U.S. history themes measured.
