The NAEP 2014 sample design consisted of a nationally representative sample of students for the following assessments:

• social studies assessments in civics, geography, and U.S. history at grade 8; 
• technology and engineering literacy (TEL) assessment at grade 8; and
• a science pilot test at grades 4, 8, and 12.

This was accomplished by designing separate sample components for public and private schools. The selected samples were based on a three-stage sample design:

• selection of primary sampling units (PSUs),
• 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 enrollment in the schools at grades 4, 8, and 12.

The target population included all students in public and private schools, including Bureau of Indian Education (BIE) and Department of Defense Domestic Dependent Elementary and Secondary Schools (DDESS), who were enrolled in grades 4, 8, and 12, respectively, at the time of assessment.

The table below shows the target student sample sizes of assessed students for each sample.
