On April 29, 2015, the National Center for Educational Statistics released the results of the Grade 8 NAEP (National Assessment of Educational Progress) tests in U.S. History, Geography and Civics. Complete results for public and Catholic school results were published; other private school levels of participation did not reach levels required for reporting more than scale scores. Catholic schools performed exceptionally well.
