The school-level nonresponse adjustment factor for the i th school in the h th class was computed as:
|equals the number of eligible sample schools in class h,|
|is the trimmed school base weight of the i th school in class h,|
|equals the grade enrollment for the i th school in class h,|
Both the numerator and denominator of the nonresponse adjustment factor contained only schools that were determined to have eligible students enrolled.
In the calculation of the above nonresponse adjustment factors, a school was said to have participated if:
it was selected for the sample from the frame or from the lists of new schools provided by participating school districts, and student assessment data were obtained from the school; or
the school participated as a substitute school and student assessment data were obtained (so that the substitute participated in place of the originally selected school).
The nonresponse-adjusted weight for the ith school in class h was computed as:
Fh(1) is the school-level nonresponse adjustment factor for the ith school in the hthclass, and
Whitsch is the trimmed school base weight of the ith school in class h
The following tables show the distribution of the school-level nonresponse adjustment factor SCNRA among the 2000 state assessment's participating jurisdictions by grade (fourth and eighth), assessment subject (mathematics and science), and reporting population. Reporting populations differ by whether students with disabilities or limited-English-proficient (SD/LEP) students were offered accommodations during testing. 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.
