The 2022 national assessment included operational assessments in mathematics and reading in public and private schools at grades 4 and 8, and operational assessments in civics and U.S. history in public and private schools at grade 8.

The sample designs aimed to achieve nationally representative samples of students in the defined populations who were enrolled at the time of assessment.  

The samples were based on a two-stage sample design:

• selection of schools within strata; and
• selection of students within schools.

The samples of schools were selected with probability proportional to a measure of size based on the estimated grade-specific enrollment in the schools.

For fourth- and eighth-grade public schools, the aggregate of the NAEP state student samples and assessments in mathematics and reading constitute the corresponding NAEP national student samples and assessments.

The samples for the remaining national assessments were organized into three distinct groupings and selected separately:

• mathematics and reading assessments in private schools at grades 4 and 8;
• civics and U.S. history assessments in public schools at grade 8; and
  
• civics and U.S. history assessments in private schools at grade 8.

All of the grade 4 and grade 8 assessments were digitally based assessments (DBA) administered using tablets.
