A Closer Look at Individual Districts

Use the tabs below to view science performance for each participating district. The profiles present a closer look at results for each district’s student groups by race/ethnicity and by income level (eligibility for free or reduced-price school lunch) and offer comparisons to the nation's public schools and to large central city public schools. In addition, results for a few, selected test questions are provided to give the reader a more concrete sense of how the district’s students performed. To learn more about the educational context in each district, see About Urban Districts.

In the table above, the “score location” of a test question on the scale represents the average scale score attained by students who had a 65 percent probability of successfully answering a constructed-response question, or a 74 percent probability of correctly answering a four-option multiple-choice question.

The scale score ranges for the science achievement levels (Basic, Proficient, and Advanced) are also displayed in the table. For constructed-response questions, the question description represents students’ performance rated as completely correct. The hyperlinked items have been released and are available in the NAEP Questions tool. To find other sample test questions with associated performance results by nation, state, and district, search the NAEP Questions Tool.

Cross-jurisdiction significance results are calculated using a multiple-comparison procedure based on all participating districts.  Results may vary from those obtained using single-district comparisons, such as those in the single-district snapshot reports.
