How are American students performing in science?
The National Assessment of Educational Progress (NAEP) has assessed the science abilities of students in grades 4, 8, and 12 in both public and private schools since 1996. As of 2009, however, NAEP science assessments are based on a new framework, so results from these assessments cannot be compared to results from earlier science assessments. Scores are based on a scale ranging from 0 to 300.
In 2009, White 4th-graders had a higher average science score (163) than did Black (127), Hispanic (131), Asian/Pacific Islander (160), and American Indian/Alaska Native (135) 4th-graders. The average science score was higher for male 4th-graders (151) than for female 4th-graders (149). In 2009, the pattern of differences in average science scores by students’ race/ethnicity at grade 8 was similar to the pattern at grade 4. The average science score also was higher for male 8th-graders (152) than for female 8th-graders (148). At grade 12, average scores for White (159) and Asian/Pacific Islander (164) students were higher than the scores for Black (125), Hispanic (134), and American Indian/Alaska Native (144) students. The average science score in 2009 for male 12th-graders (153) was higher than the score for female 12th-graders (147). In 2011, a science assessment was conducted at grade 8 only. The average 8th-grade science score increased from 150 in 2009 to 152 in 2011.
While there were no significant changes from 2009 to 2011 in the average scores for Asian/Pacific Islander or American Indian/Alaska Native 8th-graders, average scores increased 1 point for White 8th-graders, 3 points for Black 8th-graders, and 5 points for Hispanic 8th-graders. The average science score of White 8th-graders continued to be higher than the average scores of 8th-graders in all other racial/ethnic groups in 2011, but score gaps between White and Black 8th-graders and between White and Hispanic 8th-graders narrowed from 2009 to 2011. Average scores for both male and female 8th-graders were higher in 2011 than in 2009. In 2011, the average score was 5 points higher for male 8th-graders than for female 8th-graders, which was not significantly different from the 4-point gap in 2009.

‡ Reporting standards not met (too few cases for a reliable estimate).
NOTE: Scale ranges from 0 to 300 for all three grades, but scores cannot be compared across grades. For example, the average score of 163 for White 4th-graders does not denote higher performance than the score of 159 for White 12th-graders. In 2011, only 8th-grade students were assessed in science. Includes students tested with accommodations (7 to 11 percent of all students, depending on grade level and year); excludes only those students with disabilities and English language learners who were unable to be tested even with accommodations (2 to 3 percent of all students). Race categories exclude persons of Hispanic ethnicity.
