The Nation's Report Card[TM], the National Assessment of Educational Progress (NAEP), is a nationally representative and continuing assessment of what America's students know and can do in various subject areas. NAEP is a sample-based survey assessment that provides periodic reports on student academic performance at the national and state levels. The Trial Urban District Assessment (TUDA), a special project in NAEP, began assessing performance at the district level in selected large urban districts in 2002 with reading and writing assessments, and continued in 2003 and 2005 with reading and mathematics. Eleven large urban school districts participated in the 2005 NAEP reading assessment. This report provides the 2005 NAEP reading results for the participating districts. The report compares results to public school students' performance in the nation and in large central cities, and to results for the previous assessments in 2002 and 2003, where applicable, using a .05 significance level. In this report, NAEP results are presented in two ways: as average scale scores and as the percentage of students performing at or above three standards called achievement levels. NAEP reading scores are reported for grades 4 and 8 on a 0-500 scale. Separate scales are created for other subjects, so even when a subject's scale has the same numerical range (0-500), average scores should not be compared across subjects. The report is divided into the following sections: (1) Executive Summary; (2) Introduction and Overall Performance; (3) Student Group Results; (4) Performance Trends; (5) Framework and Sample Questions; and (6) Technical Notes and Data Appendix.
