About NAEP and International Assessments

coordinationCoordination of NAEP and International Assessment Administrations

The NAEP assessments in for mathematics, reading, and science are now coordinated with three NCES international assessments:

  • Progress in International Reading Literacy Study (PIRLS),
  • Program for International Student Assessment (PISA), and
  • Trends in International Mathematics and Science Study (TIMSS).

This coordination will produce complementary results for more useful comparisons between international assessments and NAEP.

See the results of the 2011 NAEP-TIMSS Linking Study, a study that links national and international results and allows a comparison of 2011 state mathematics and science results to the results of other nations. Download the brochure, NAEP-TIMSS Linking Study PDF File (1.2 MB) for more information. Read comparisons between NAEP and TIMSS research reports.

The table below illustrates the years in which NAEP and PIRLS, PISA, or TIMSS have planned coincidence in order to gain comparable information about our nation's students. Also, take a look at the schedule for NAEP and other NCES assessment activities for the current year.

comparisonsComparisons of NAEP and International Assessments

When comparing results of NAEP with those of international assessments, it is important to consider the differences among them in terms of assessment purpose, content, target population, administration, and results.

onlineOnline Tools and Features of NAEP, PIRLS, PISA, and TIMSS

See NAEP results for each subject on the Nation's Report Card website, and NAEPPIRLSPISA, and TIMSS websites each provide public access to released questions, student and school questionnaires, tools for custom analyses such as the NAEP Data Explorer (NDE) and the International Data Explorer (IDE), and micro data for researchers. Get more information about the international assessments on the International Activities Program (IAP) home page.
