Final participation, exclusion, and accommodation rates are presented in quality control tables for each grade and subject by geographic domain and school type. School and student-level participation rates have been calculated according to National Center for Education Statistics (NCES) standards as they have been for previous assessments.

At the school level, the overall national private school domain at grades 4 and 8 had participation rates below 85 percent. At the student level, there were two reporting subgroups with participation rates below 85 percent, New York state for both mathematics and reading at grade 8 and the Washington, DC public school TUDA district for mathematics at grade 8. As required by NCES standards, nonresponse bias analyses were conducted on each reporting group falling below the 85 percent participation threshold.
