NAEP Technical DocumentationSummary of Quality Control Error Analysis for NAEP 2000 Data Entry
The following illustrative summary table for 2000 gives the upper 99.8 percent confidence limit for the error rate 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. Since this information is not routinely calculated, this table is not available for 2001.
