Final participation, exclusion, and accommodation rates were presented in quality control tables for each age and session type by Census region for public schools, and by type of school for private schools. School rates were calculated as they had been calculated for previous assessments and according to National Center for Education Statistics (NCES) standards.

Overall school-level participation rates were below 85 percent for public schools for age 17, and for private schools at all three ages. Overall student-level participation rates were also below 85 percent for 17 year-old students in public and private schools. As required by NCES standards, nonresponse bias analyses were conducted on each student group falling below the 85 percent participation threshold.
