NOTE: The NAEP science scale ranges from 0 to 300. In 2019, the digitally based NAEP science assessment was administered for the first time. The 2019 science report includes results from students who took the digitally based assessment and students who took the paper-based assessment. The 2009, 2011, 2015, and 2019 NAEP science assessments were based on a new science framework introduced in 2009, which replaced the one used for the 1996, 2000, and 2005 assessments. The 2009 framework started a new NAEP science trend line so the results from the 2009, 2011, 2015, and 2019 assessments cannot be compared to those from previous assessment years. The 2011 NAEP science assessment for grade 8 was a special administration to permit comparisons with the Trends in International Mathematics and Science Study (TIMSS). Detail may not sum to totals because of rounding or the omission of categories. Although the estimates (e.g., average scores or percentages) are shown as rounded numbers in the charts, the positions of the data points in the graphics are based on the unrounded numbers. Unrounded numbers were used for calculating the differences between the estimates, and for the statistical comparison test when the estimates were compared to each other. Not all apparent differences between estimates are statistically significant.
