NAEP Technical DocumentationDevelopment of Initial School Nonresponse Cells for the 2010 Assessment

The cells for nonresponse adjustments are generally functions of the school sampling strata for the individual samples. For NAEP 2010, school sampling strata were the same by grade and subject, but differed by school type (public or private). Assessment subjects that are administered together by way of spiraling have the same school samples and stratification schemes. Subjects that are not spiraled with any other subjects have their own separate school sample. In NAEP 2010, the geography and U.S. history assessments were spiraled together, but civics was not spiraled with any other operational subject. 

The description of the initial nonresponse cells for the 2010 NAEP samples is given below.

Public School Samples

For public school samples, initial weighting cells were formed within each grade and subject using the following nesting cell structure:

• census region;

• urbanicity (urban-centric locale) stratum; and
• race/ethnicity classification.

Private School Samples

For private school samples, initial weighting cells were formed within each grade and subject using the following nesting cell structure:

• census region;
• affiliation (Catholic or non-Catholic); and
• collapsed urbanicity (collapsed urban-centric locale) stratum.
