This indicator represents the proportion of a state's fourth grade students in public schools that has met or exceeded the proficiency standard in science. The National Assessment Governing Board sets performance standards that provide a context for interpreting National Assessment of Educational Progress (NAEP) results. The standards define "proficiency," as well as "advanced" and "basic" accomplishment. For the fourth grade, the proficient level (scores 167–223) represents solid academic performance and demonstrates competency over challenging subject-matter knowledge. The advanced level (224–300) signifies superior performance. The basic level (131–166) denotes partial mastery of knowledge and skills that are prerequisite for proficient work.
The National Center for Education Statistics has advised that science achievement levels are to be used on a trial basis and should be interpreted with caution. Approximately 156,500 fourth grade students in 9,330 schools participated in the 2009 NAEP science assessment. A designation of NA (not available) indicates that the state either did not participate in the assessment or did not meet minimum guidelines for reporting. NAEP allows students with disabilities or limited English-language proficiency to use certain accommodations (e.g., extended time, individual testing, or small group testing). All data presented here represent scores from tests taken with accommodations offered.
