International and U.S. Response Rates - Response Rates

Return to Methodology and Technical Notes

Table AB-1 provides information on weighted school participation rates before and after school replacement and the number of participating schools after replacement for each participating education system. Table AB-2 provides information on coverage of the target population, overall exclusion rates, weighted student response rates after school replacement, and the number of participating students after replacement for each participating education system.

One hundred thirty-nine participating original schools and 23 replacement schools participated in the U.S. administration of the Program for International Student Assessment (PISA), for a total of 162 schools. Although all 162 schools were included in the analysis of the U.S. PISA 2012 results, international guidelines stipulated that schools with between 25 and 50 percent of students participating were considered nonparticipating schools for the purposes of calculating response rates (but were eligible to be included in the analysis of results). In the United States, one replacement school had a student response rate between 25 and 50 percent. This resulted in 161 participating schools and an overall weighted school response rate of 77 percent. The overall weighted student response rate was 89 percent and the U.S. overall student exclusion rate was 5 percent.

In Connecticut, there were 50 participating schools (out of 51 eligible schools), resulting in an overall weighted school response rate of 98 percent. The overall weighted student response rate was 87 percent and the overall student exclusion rate was 4 percent. In Florida, there were 54 participating schools (out of 54 eligible schools), resulting in an overall weighted school response rate of 100 percent. The overall weighted student response rate was 90 percent and the overall student exclusion rate was 8 percent. In Massachusetts, there were 49 participating schools (out of 49 eligible schools), resulting in an overall weighted school response rate of 100 percent. The overall weighted student response rate was 90 percent and the overall student exclusion rate was 4 percent.

NOTE: In calculating school participation rates, each school received a weight equal to the product of its base weight (the reciprocal of its probability of selection) and the number of age-eligible students enrolled in the school, as indicated on the sampling frame. Weighted school participation before replacement refers to the sum of weights of the original sample schools with PISA-assessed students and a student response rate of at least 50 percent over the sum of weights of all original sample schools. Weighted school participation after replacement refers to the sum of weights of the original and replacement schools with PISA-assessed students and a student response rate of at least 50 percent over the sum of weights of responding original sample schools, responding replacement schools, and eligible refusing original sample schools. Italics indicate non-OECD countries and education systems. Results for Connecticut, Florida, and Massachusetts are for public schools only. This table corresponds to table B-1 in Performance of U.S. 15-Year-Old Students in Mathematics, Science, and Reading Literacy in an International Context (NCES 2014-024).

NOTE: In calculating student participation rates, each student received a weight (student base weight) equal to the product of the school base weight—for the school in which the student was enrolled—and the reciprocal of the student selection probability within the school. Coverage of 15-year-old population refers to the extent to which the weighted participants covered the target population of all enrolled students in grades 7 and above. Coverage of national desired population refers to the extent to which the weighted participants covered the national population of 15-year-olds under the nonexcluded portion of the student sample. Overall student exclusion rate is the percentage of students excluded for intellectual or functional disabilities, or insufficient assessment language experience at either the school level or within schools. Weighted student participation after replacement refers to the sum of weights of students in original and replacement schools with PISA-assessed students and a student response rate of at least 50 percent over the sum of weights of students in responding original sample schools, responding replacement schools, and eligible refusing original sample schools. Italics indicate non-OECD countries and education systems. Results for Connecticut, Florida, and Massachusetts are for public school students only.
