The Nation’s Report Card: Science 2009
"This report presents results of the 2009 National Assessment of Educational Progress (NAEP) in science at grades 4, 8, and 12. National results for each of the three grades are based on representative samples of public and private school students from all 50 states, the District of Columbia, and the Department of Defense schools. State results are reported separately for fourth- and eighth-grade public school students from 46 states and the Department of Defense schools. Student performance is summarized as average scores and as percentages of students performing at or above three achievement levels: Basic, Proficient, and Advanced. Results for student demographic groups (e.g., race/ethnicity, gender, and type of school location) are included, as well as sample assessment questions with examples of student responses. The Technical Notes and appendix tables provide information on NAEP samples, school and student participation rates, the exclusion and accommodation rates of students with disabilities and English language learners, and additional state-level results..."
