Final Collapsed Levels Used for Raking Dimensions
Five variables were used for the raking dimensions. These variables included
Collapsing of levels was done so that no level of a single dimension contained fewer than 30 students for a state and grade.
Control totals were obtained by summing the trimmed nonresponse-adjusted student weights for each level of the collapsed raking dimension. The final collapsed levels that were used for the raking dimensions for each jurisdiction are shown for each assessment population, in the following tables:
After raking, the same trimming procedure as described in Variation in Weights was conducted on the raked student weights. Additional trimming of weights was necessary under the same criteria as discussed in that same section.
The tables below show the distribution of the post-raking trimming factor STUTRIM2 among the 2000 state assessment's participating jurisdictions by grade (fourth and eighth), assessment subject (mathematics and science), and reporting population (non-accommodated and accommodated). Reporting populations differ by whether accommodations were offered to students with disabilities or limited-English-proficient (SD/LEP) students. The non-accommodated reporting population, also known as the R2 reporting population, includes all non SD/LEP students plus SD/LEP students from non-accommodated sessions. The accommodated reporting population, also known as the R3 reporting population, includes all non SD/LEP students plus SD/LEP students from accommodated sessions.
