These online Highlights present an overview of results from the NAEP 2019 science report. Highlighted results include key findings for nationally representative samples of fourth-, eighth-, and twelfth-grade students. Results are presented in terms of average scale scores and as percentages of students performing at the three NAEP achievement levels: NAEP Basic, NAEP Proficient, and NAEP Advanced. In addition to the overall average scale score, NAEP science results are also reported as average subscale scores for each of three content areas—Physical Science, Life Science, and Earth and Space Sciences. Highlighted results also include performance data for demographic student groups, scores at five selected percentiles, and responses to NAEP survey questionnaires

The 2019 average science score was lower for grade 4, and not significantly different for grades 8 and grade 12, compared to average scores in 2015. Average science scores were higher for grades 4 and 8, but not significantly different for grade 12, compared to 2009, the first year under the current science framework. Compared to 2015, the average score was lower for grade 4 in two of the three science content areas; there were no significant changes in average content areas scores for grades 8 and 12. Average scores were higher in two of the three content areas for grades 4 and 8 compared to 2009 while there were no significant changes in average scores across the content areas for grade 12.

Reported results include responses of students, teachers, and school administrators to survey questionnaires designed to collect information about student’s educational experiences and opportunities to learn both inside and outside of the classroom. The report includes detailed descriptions of released interactive scenario-based tasks and discrete questions to illustrate the types of science knowledge and scientific inquiry skills that were measured as part of the NAEP science assessment.
