The sample design for NAEP 2019 included samples for various operational and special studies.
Representative samples were drawn for the following operational assessments:
- national assessment in science in public and private schools at grades 4 and 8; and
- national assessments in mathematics, reading, and science in public and private schools at grade 12; and
- state-by-state assessments and Trial Urban District Assessments (TUDA) in mathematics and reading in public schools at grades 4 and 8.
Representative samples were drawn for the following special studies and pilot assessments:
- national mathematics, reading, and vocabulary initial pilot tests in public and private schools at grades 4 and 8; and
- The National Indian Education Study (NIES) at grades 4 and 8.
The samples for the operational assessments were organized into six distinct groupings and sampled separately. The samples for the special studies were integrated into these various groupings:
- mathematics and reading assessments in public schools at grades 4 and 8;
- mathematics and reading assessments in private schools at grades 4 and 8;
- science assessment in public schools at grades 4 and 8;
- science assessment in private schools at grades 4 and 8;
- mathematics, reading, and science assessments in public schools at grade 12; and
- mathematics, reading, and science assessments in private schools at grade 12.
In 2019, digitally based assessments (DBA) using tablets were administered in addition to paper and pencil assessments (PBA) at the operational level. Specifically, for the mathematics and reading assessments at grades 4 and 8, all students were administered DBA using tablets. For the mathematics and reading assessments at grade 12 and science assessment at grades 4, 8, and 12, students were assigned to either DBA or PBA during student sample selection.
The national assessments were designed to achieve nationally representative samples of public and private school students in the fourth, eighth, and twelfth grades. Their target populations included all students in public, private, Bureau of Indian Education (BIE), and Department of Defense Education Activity (DoDEA) schools, who were enrolled in grades 4, 8, and 12 at the time of assessment.
For the fourth- and eighth-grade mathematics and reading assessments in public schools, the TUDA samples formed part of the corresponding state public school samples, and the state samples formed the public school grades 4 and 8 part of the national sample. Nationally representative samples were drawn for science and for the remaining populations of private school students, DoDEA students, and BIE students in the fourth, eighth, and twelfth grades.
The state assessments were designed to achieve representative samples of students in the respective grade. At grades 4 and 8, the target populations included all students in each participating jurisdiction, which included states, District of Columbia, BIE, DoDEA, and school districts chosen for the TUDA. For each grade and assessment subject, samples were designed to produce aggregate estimates with adequate precision for all the participating jurisdictions, as well as estimates for various student subpopulations of interest.
The figure below illustrates the various sample types and subjects.
