ED's National Center for Education Statistics (NCES) is the main federal organization responsible for collecting and analyzing data related to education.
The NCES FastFacts page provides quick statistical answers to basic questions about education, such as Are American students performing better in reading now than in the past? and How many educational institutions exist in the U.S.?
The Nation's Report Card presents the results of the National Assessment of Educational Progress (NAEP), which measures student achievement in the U.S. in various subjects over time.
The Tables and Figures search lets you search from one location all the tables, figures, and charts published in a number of large data collections and publications.
NCES provides data tools that let you locate schools with certain characteristics, build custom tables from NCES data, and view state and school district profiles.
