Who are the students assessed by NAEP?
The national results are based on a representative sample of students in public schools, private schools, Bureau of Indian Affairs schools, and Department of Defense schools. Private schools include Catholic, Conservative Christian, Lutheran, and other private schools. The state results are based on public school students only. The long-term trend assessments report results for age samples 9, 13, and 17 in public and nonpublic schools. In the past, they have measured students’ achievements in mathematics, science, reading, and writing. However, beginning with the 2003–2004 long-term trend assessment, only mathematics and reading are assessed in long-term trend NAEP.
