Nationally representative samples of about 187,000 fourth-graders, 170,000 eighth-graders, and 46,000 twelfth-graders participated in the 2013 NAEP mathematics assessment.
See the national/state results for grade 12.
In 2013, representative samples of approximately 4,600 fourth-grade students from 150 public schools and 5,200 eighth-grade students from 120 public schools in Puerto Rico participated in a Spanish-language version of the NAEP mathematics assessment.
See the results of the Puerto Rico mathematics assessment.
Twenty-one urban districts participated in the 2013 NAEP Trial Urban District Assessment (TUDA)
assessments in mathematics and reading. The assessments administered in TUDA are exactly the same as those given nationally and use identical administration procedures. Results in mathematics and reading are based on
representative samples of 1,100 to 2,300 public school students at grade
4 and 900 to 2,100 public school students at grade 8 in each
participating urban district in 2013.
