This indicator represents the proportion of a state's eighth grade students in public schools that has met or exceeded the proficiency standard in science.
The National Assessment of Educational Progress (NAEP) provides a federally authorized measure of student performance in science. The National Assessment Governing Board sets performance standards that provide a context for interpreting NAEP results. The standards define "proficiency" as well performance levels that indicate greater ("advanced") and lesser ("basic") accomplishment. For the eighth grade, the proficient level (scores 170–207) represents solid academic performance and demonstrates competency over challenging subject-matter knowledge, its application to real-world situations, and mastery of appropriate analytical skills. The advanced level (208–300) signifies superior performance. The basic level (143–169) denotes partial mastery of knowledge and skills that are prerequisite for proficient work. A National Academy of Sciences panel evaluated the process used to establish the standards for the science assessment and urged that they be considered developmental and interpreted with caution.
Approximately 143,400 eighth grade students in 6,400 schools participated in the 2005 NAEP science assessment. A designation of NA (not available) indicates that the state either did not participate in the assessment or did not have a representative sample of eighth graders that was large enough for reporting state-level results.
