NAEP Analysis and Scaling → Summary Statistics for Scale Scores of Groups → Reporting Groups and Special Variables Reporting Groups and Special Variables
The groups for which subpopulation mean scale scores are available are defined by student, teacher, and school background variables or by variables used in the sampling of schools for NAEP. Some of the background variables are specific to the subject area being assessed and are collected as subject-specific background questions on the questionnaires; others are not specific to a subject area. Variables that are derived from one or more background questions are defined here. Some of the variables used to define groups come from external sources used in the sampling process.
