Sampling Stages

2000 National Main Assessment

  • Fourth- and twelfth-grade students

    • Selected geographic primary sampling units

    • Selected schools from primary sampling units

    • Assigned sessions to schools

    • Selected students from schools

  • Eighth-grade students

    • Selected schools within the integrated national and state samples

    • Assigned sessions to schools

    • Selected students from schools

2000 State Assessment

  • Sampling began within a participating state/jurisdiction

  • Selected schools from jurisdiction

  • Assigned sessions to schools

  • Selected students from schools

The integrated approach of the 2000 national main and state assessment for eighth-grade school samples combined the national and state samples after data collection. This approach produced a larger sample that yielded more precise estimates. Because the state assessment focused on public schools, no private school students appeared in the 2000 national main assessment eighth grade.
