See how U.S. fourth-, eighth-, and twelfth-grade students performed in science
Between January and March 2019, the National Assessment of Educational Progress (NAEP) science assessment was administered to a nationally representative sample of fourth-, eighth-, and twelfth-grade students. Results are compared to those from 2015 and previous science assessments back to 2009, the first year under the current science framework.
This Report Card Highlights provides key findings from the 2019 science assessment. See the NAEP Science Report Card to explore the full set of student performance results and information about students’ learning experiences inside and outside of school. You may also download a summary of the science results.
OVERALL SCIENCE PERFORMANCE AT GRADES 4, 8, AND 12
Science scores decrease at grade 4; no significant changes at grades 8 and 12 compared to 2015
Fourth- and eighth-graders score higher compared to 2009; no significant change for twelfth-graders
In 2019, the average science score at fourth grade was lower by 2 points compared to 2015 while the score was higher by 1 point compared to 2009. At grade 8, the average score was not significantly different compared to 2015 but was four points higher compared to 2009. The average score at grade 12 in 2019 was not significantly different in comparison to 2015 and 2009.
Lower scores for fourth-grade students in two of three science content areas; no significant changes in content area scores for eighth- and twelfth-graders compared to 2015

The NAEP science assessment measures students’ knowledge and abilities in three content areas—Physical Science, Life Science, and Earth and Space Sciences. Learn more about the science content areas.
In 2019, average scores at grade 4 declined in Life Science and Earth and Space Sciences compared to 2015, while scores were higher in Physical Science and Earth and Space Sciences than in 2009. At grade 8, there were no significant changes in average scores across the three content areas in 2019 compared to 2015, while Physical Science and Life Science scores were higher than in 2009. There were no significant changes in average scores across the content areas at grade 12 compared to 2015 and 2009.
