The National Assessment of Educational Progress (NAEP) is the largest nationally representative and continuing assessment of what America's students know and can do in various subject areas. Assessments are conducted periodically in mathematics, reading, science, writing, the arts, civics, economics, geography, U.S. history, and beginning in 2014, in Technology and Engineering Literacy.

Since NAEP assessments are administered uniformly using the same sets of test booklets across the nation, NAEP results serve as a common metric for all states and selected urban districts. The assessment stays essentially the same from year to year, with only carefully documented changes. This permits NAEP to provide a clear picture of student academic progress over time. 
 
The Trial Urban District Assessment (TUDA) is designed to explore the feasibility of using National Assessment of Educational Progress (NAEP) to report on the performance of public school students at the district level. As authorized by federal law, NAEP has administered the mathematics, reading, science, and writing assessments to samples of students in selected urban districts public schools.
