The charts below allow for comparisons to be made between district science performance and the performance for the nation and large cities nationally.

  • In the Comparison to National Results tab below, performance for public school students in large cities and various districts is compared to the national averages. An up or down arrow for each student group indicates whether scores or percentages in the district were higher or lower than the national average.
  • In the Comparisons to Large City Results tab, an up or down arrow for each student group indicates whether scores or percentages in the district were higher or lower than the average score for public school students in large cities nationally.
  • In the tabs showing performance gaps, click on any "sort" button to rank districts numerically by the data in that column. Click on a jurisdiction to see how other jurisdictions compare in terms of statistical significance.
Average Scores
Percentage at or Above Basic

 The score gap between White and Black students was narrower in Jefferson County (KY) than in large city schools nationally.

Average scale scores and score gaps for White and Black students in eighth-grade NAEP science, by jurisdiction: 2009

Legend
> Score was higher or gap was wider than selected jurisdiction
< Score was lower or gap was narrower than selected jurisdiction
X Not significantly different from selected jurisdiction

The order of jurisdictions is based on numeric precision (up to eight decimal places) rather than the displayed precision and does not take statistical significance into consideration. To see whether there is a significant difference between jurisdictions, consult the column "Cross-jurisdiction significant difference."
