Knowledge of U.S. History
- From the mid-1990s to 2014, eighth graders’ history achievement improved. The percentage of students in the eighth grade scoring at the proficient achievement level or above in U.S. history increased by a statistically significant margin. In 2014, 18% of all eighth-grade students demonstrated proficiency, up from 14% in 1994. At the other end of the achievement scale, a smaller share of students scored at the below basic level in 2014 than in 1994. However, reflecting the slow upward trend of achievement, there was no statistically significant change from 2010 to 2014 (the two most recent assessments, as of January 2016) in the share of students scoring at either of these levels (Indicator I-05a).
- Fourth and 12th graders were most recently tested in 2010. The share of students demonstrating proficiency in American history increased by a statistically significant margin only among the fourth graders (Indicator I-05b). In 2010, 20% of fourth-grade students demonstrated proficiency, up from 17% in 1994. In both 1994 and 2010, a greater proportion of fourth-grade students demonstrated proficiency in U.S. history than did 12th graders.
- In every testing year, a substantial majority of children in the assessed grades failed to demonstrate proficiency in U.S. history. The absence of long-term trend data prevents a systematic evaluation of how recent a phenomenon this is, but research reveals that young people’s ignorance of U.S. history has been a source of public concern since the beginning of the 20th century.2

Although it was introduced later and is given less frequently than the reading assessment (see the indicators under the topics “Trends in Basic Reading Skills among School-Age Children” and “Reading Proficiency Relative to that in Science and Math”), the NAEP for U.S. history also supplies data describing change over time in students’ knowledge of a core humanities subject. (For information on state policies regarding the teaching of history at the precollegiate level, consult the National History Education Clearinghouse’s Fall 2011 update to its 2010 Report on the State of History Education.) The NAEP history scores are reported here by achievement level.
