|Figure 14-1: Percentage of students who performed at or above the proficient achievement level in science, by grade and school poverty level: 2009|
NOTE: The National Assessment of Educational Progress (NAEP) science achievement levels define what students should know and be able to do. Proficient indicates demonstrated competency over challenging subject matter, and Advanced indicates superior performance. The percentage of students at or above Proficient includes students at the Proficient and the Advanced achievement levels. High-poverty schools are defined as public schools where more than 75 percent of the students are eligible for the free or reduced-price lunch (FRPL) program, and mid-high poverty schools are those schools where 51 to 75 percent of students are eligible. Low-poverty schools are defined as public schools where 25 percent or fewer students are eligible for FRPL, and mid-low poverty schools are those schools where 26 to 50 percent of students are eligible for FRPL. For more information on free or reduced-price lunch, see supplemental note 1. For more information on NAEP, see supplemental note 4.
