NAEP Long-Term Trend Report for Ages 9 and 13

A new report reveals how a nationally representative sample of 9- and 13-year-old students performed on the 2019–20 National Assessment of Educational Progress (NAEP) long-term trend assessments in reading and mathematics. The report compares overall average scores, selected percentiles, and performance-level results over time. Long-term trend assessments were first administered in the early 1970s; results are available for 13 prior reading assessments dating back to 1971 and 12 prior mathematics assessments dating back to 1973. The previous long-term trend assessment occurred in 2012. Item maps for each age group illustrate skills demonstrated by students when responding to assessment questions. The report also includes results for students by selected background characteristics (for example, race/ethnicity, gender). Responses to the student questionnaire and information on demographic changes in the student population provide additional context for interpreting student performance results.
