The NAEP 2010 geography assessment was administered nationally to students in grades 4, 8, and 12. More than 7,000 fourth-graders, 9,500 eighth-graders, and 10,000 twelfth-graders participated in the 2010 assessment
NAEP does not, and is not designed to, report on the performance of individual students. Instead it assesses groups of the student population from representative national samples. For example, NAEP reports results for male and female students, black and white students, and students in different regions of the country. Samples are selected using a complex sampling design.
