Number of Bundle Types for the 2008 Assessment
NAEP booklets are spiraled according to the pattern dictated by the NAEP instrument development staff in the bundle maps. Booklets are spiraled in such a manner as to capture the sample size needed for each subject per grade. Each bundle contains the specified number of documents and a bundle slip (or header sheet). This bundle slip indicates the bundle type, bundle number, unique barcode number, the first three digits of each booklet type in the bundle, and the alpha character for those booklets assigned an ancillary item.
The booklets from various subject areas must be handed out in the field according to a booklet distribution map specified by the instrument development contractor. Spreading the booklets for each subject area across almost all of the schools both increases the efficiency of the sampling and simplifies the weighting processes. It also assures that there will be as little waste of materials as possible, while still providing enough booklets for each session to account for unexpected needs for booklets. However, in an assessment year in which there are two or three operational assessments, field tests, and special studies, the spiral plan becomes quite complex. When subject areas have an unequal number of blocks in their booklet designs, they will also have different numbers of booklets. To achieve appropriate sample sizes for each subject area, the spiral must be assembled so that the booklets occur at precise intervals.
Once all bundles pass the bundle quality control process, each bundle is shrink-wrapped and flagged on the system as ready for distribution. Information from the bundle quality control file is then uploaded to the mainframe computer system and used for the preprinting of administration schedules.
