Grade 12 students' average reading score declined by 2 points since 2015 according to the 2019 National Assessment of Educational Progress, while their average mathematics score did not change. Scores also declined for lower-performing students in both subjects at grades 4, 8, and 12. The percentage of students performing at or above the proficient level held steady at 37% for reading and 24% for mathematics. The results indicate that gaps are widening between lower- and higher-performing students.
