NAEP Technical DocumentationSummary of Quality Control Error Analysis for NAEP 2009 Data Entry

The following summary tables give the upper 99.8 percent confidence limit for the error rates for each of the instruments as well as the sampling information. The 99.8 percent confidence limit and the selection rates indicated were chosen to make these results comparable to those of administrations since 1983, all of which used the same parameters. There were no teacher questionnaires administered at grade 12.
