Elementary and Secondary Education

Eighth grade science proficiency



Findings

  • In 2009, 29% of eighth grade public school students nationwide performed at or above the proficient level in science. Among the states, there were significant differences in the percentage of eighth grade public school students who demonstrated proficiency in science. State values for this indicator ranged from 15% to 43%.
  • Nationally, the percentage of eighth grade white students demonstrating proficient performance in science was 41% compared to 12% for Hispanic students and 8% for black students.
  • A gender difference was reported with 32% of male eighth grade public school students scoring at or above the proficient level in science compared to 26% of female eighth grade public school students. The range by state was 17%–47% for males and 13%–38% for females.


Description

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 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 eighth grade, the proficient level (scores 170–214) represents solid academic performance and demonstrates competency over challenging subject-matter knowledge. The advanced level (215–300) signifies superior performance. The basic level (141–169) denotes partial mastery of knowledge and skills that are prerequisite for proficient work. The National Center for Education Statistics has determined that achievement levels are to be used on a trial basis and should be interpreted with caution.

Approximately 151,100 eighth grade students in 6,920 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.
