HSTS 2005 provides results related to NAEP science and mathematics achievement. Why aren results reported for NAEP reading achievement, also a part of NAEP in 2005?
The administration of the HSTS was designed to correspond to the years that NAEP mathematics and science assessments were given. Even though in 2005 NAEP administered assessments in reading, mathematics, and science, transcripts were collected only for students who took the mathematics or science assessments.
