School and Student Participation in the 2005 State Assessment

In all cases in the 2005 state assessment, the weighted response rates for schools in each jurisdiction exceeded the 85 percent standard established by NCES. The one exception was the Bureau of Indian Affairs (BIA) schools at grade 4 (83.4 percent), but this was not a major concern because the BIA sample was not designed as a reportable jurisdiction. 

In 2003, following the introduction of mandated state and district participation in reading and math at grades 4 and 8, substitutes were provided, but none were used in any state. Therefore, as a cost saving measure, no substitutes were provided for these assessments in 2005.

Response Rates of Fourth-Grade School Sample by Participating Jurisdiction

Response Rates of Eighth-Grade School Sample by Participating Jurisdiction

In every NAEP survey, some of the sampled students are not assessed for the following reasons:

  • withdrawn students,
  • excluded students with disabilities (SD),
  • excluded English language learner (ELL) students, and
  • students absent from both the original session and the make-up session (not excluded but not assessed).

Withdrawn students are those who have left the school before the original assessment. Excluded students are those who cannot be assessed even with an accommodation because they are disabled (SD) or are English language learners (ELL). Other students who were absent for the initial session are assessed in the makeup session. The last category includes students who were not excluded (i.e., “were to be assessed”) but were not assessed either due to absence from both sessions or because of a refusal to participate. Assessed students are also classified as assessed without an accommodation or assessed with an accommodation. The latter group can be divided into SD students assessed with an accommodation, ELL students assessed with an accommodation, or students who are both SD and ELL and accommodated (students neither SD nor ELL can only be assessed without an accommodation). Note that some SD and ELL students are assessed without accommodations.

The weighted response rates utilize the student base weights and indicate the weighted percentage of assessed students as a percentage of all students to be assessed. The exclusion rates, in contrast, provide the weighted percentage of excluded SD or ELL students as a percentage of all absent, assessed, and excluded students
