The Nation's Report Card: Science 2009 Trial Urban District Assessment (TUDA) (NCES 2011-452)

Seventeen large urban school districts participated as independent jurisdictions in the 2009 National Assessment of Educational Progress (NAEP) in science. Representative samples of fourth- and eighth-grade public school students took the assessment. Students responded to questions designed to measure their knowledge and abilities in physical science, life science, and Earth and space sciences. All results are presented in the form of NAEP scale scores and percentages of students at the Basic, Proficient, and Advanced achievement levels.
