In the United States, 8th-grade exams typically cover a range of subjects, including mathematics, language arts, science, and social studies. The scores for these subjects vary depending on the specific exam and the standards set by the state or district. For instance, the National Assessment of Educational Progress (NAEP) assesses students in reading, mathematics, science, and writing. In 2021, the average scores for 8th-grade students were as follows: reading - 267 (out of 500), mathematics - 285, science - 262, and writing - 277. These scores reflect the national average and can vary significantly across different states and districts. The scores are used to evaluate student performance, identify areas of strength and weakness, and inform educational policies and practices.
