A representative sample of 122,000 eighth-graders participated in the 2011 National Assessment of Educational Progress (NAEP) science assessment, which is designed to measure students' knowledge and abilities in the areas of physical science, life science, and Earth and space sciences. This report covers the overall results, achievement level percentages and average score results, comparison of the average scores in 2009 and 2011 to other states/jurisdictions, average scores for state/jurisdiction and nation (public), results for student groups in 2011, and score gaps for student groups. In 2011, the average score of eighth-grade students in Alabama was 140. This was lower than the average score of 151 for public school students in the nation. The average score for students in Alabama in 2011 (140) was not significantly different from their average score in 2009 (139). In 2011, the score gap between students in Alabama at the 75th percentile and students at the 25th percentile was 46 points. This performance gap was not significantly different from that of 2009 (49 points). The percentage of students in Alabama who performed at or above the NAEP "Proficient" level was 19 percent in 2011. This percentage was not significantly different from that in 2009 (19 percent). The percentage of students in Alabama who performed at or above the NAEP "Basic" level was 53 percent in 2011. This percentage was not significantly different from that in 2009 (51 percent). [For the main report, "The Nation's Report Card: Science 2011. National Assessment of Educational Progress at Grade 8.
