The online interactive NAEP Data Tool provides tables of detailed results from NAEP's national and state assessments.
	The NAEP Data Tool, available on the NAEP web site, provides easy-to-use information at a level of detail sufficient for most users. An online tutorial is available. Released NAEP questions with full item statistics are available on the NAEP web site. Researchers may be interested in more detailed data for complex analysis and research. Access to the full array of NAEP data is available to licensed users through a restricted-use database. Organizations may apply to NCES for a license to use restricted-use data.
