The National Assessment of Educational Progress (NAEP) mathematics assessment is given every two years to students at grades 4 and 8, and approximately every four years at grade 12. The assessment measures both mathematics knowledge and the students’ ability to apply their knowledge in problem-solving situations. The results present a broad view of students’ mathematics knowledge, skills, and performance over time. The most recent mathematics assessment was given in 2019 to approximately 149,500 grade 4 students, 147,400 grade 8 students, and 25,400 grade 12 students.
