Why are there no NAEP trend data included in the 2005 HSTS report?
The NAEP mathematics assessment in 2005 was based on a new assessment framework. Therefore, the 2005 mathematics results cannot be compared with previous mathematics assessments. Because the pattern of results is similar to that found in 2000 for science, it was decided to report NAEP science results only for 2005 in the HSTS report. The only science assessment conducted under the present NAEP framework prior to 2000 was done in 1996, a year in which transcripts were not collected.
