Results from the National Assessment of Educational Progress, or NAEP, released Tuesday show scores for 12th graders declined in math and reading for all but the highest performing students, as well as widening gaps between high and low performers in math. More than half of these students reported being accepted into a four-year college, but the test results indicate that many of them are not academically prepared for college, officials said.
“This means these students are taking their next steps in life with fewer skills and less knowledge in core academics than their predecessors a decade ago, and this is happening at a time when rapid advancements in technology and society demand more of future workers and citizens, not less,” said Lesley Muldoon, executive director of the National Assessment Governing Board. “We have seen progress before on NAEP, including greater percentages of students meeting the NAEP proficient level. We cannot lose sight of what is possible when we use valuable data like NAEP to drive change and improve learning in U.S. schools.”
Amidst declines, the gap between low and high performers widened for 12th graders

The math test measures students’ knowledge in four areas: number properties and operations; measurement and geometry; data analysis, statistics, and probability; and algebra. The average score was the lowest it has been since 2005, and 45% of students scored below the NAEP Basic level, even as fewer students scored at NAEP Proficient or above.
NAEP Proficient typically represents a higher bar than grade-level proficiency as measured on state- and district-level standardized tests. A student scoring in the proficient range might be able to pick the correct algebraic formula for a particular scenario or solve a two-dimensional geometric problem. A student scoring at the basic level likely would be able to determine probability from a simple table or find the population of an area when given the population density.
Only students in the 90th percentile — the highest achieving students — didn’t see a decline, and the gap between high- and low-performing students in math was higher than on all previous assessments.
This gap between high and low performers appeared before the pandemic, but has widened in most grade levels and subject areas since. The causes are not entirely clear but might reflect changes in how schools approach teaching as well as challenges outside the classroom.
Testing officials estimate that 33% of students from the class of 2024 were ready for college-level math, down from 37% in 2019, even as more students said they intended to go to college.
In reading, students similarly posted lower average scores than on any previous assessment, with only the highest performing students not seeing a decline.
The reading test measures students’ comprehension of both literary and informational texts and requires students to interpret texts and demonstrate critical thinking skills, as well as understand the plain meaning of the words.
A student scoring at the basic level likely would understand the purpose of a persuasive essay, for example, or the reaction of a potential audience, while a students scoring at the proficient level would be able to describe why the author made certain rhetorical choices.
Roughly 32% of students scored below NAEP Basic, 12 percentage points higher than students in 1992, while fewer students scored above NAEP Proficient. An estimated 35% of students were ready for college-level work, down from 37% in 2019.
In a survey attached to the test, students in 2024 were more likely to report having missed three or more days of school in the previous month than their counterparts in 2019. Students who miss more school typically score lower on NAEP and other tests. Higher performing students were more likely to say they missed no days of school in the previous month.
Students in 2024 were less likely to report taking pre-calculus, though the rates of students taking both calculus and algebra II were similar in 2019 and 2024. Students reported less confidence in their math abilities than their 2019 counterparts, though students in 2024 were actually less likely to say they didn’t enjoy math.
Students also reported lower confidence in their reading abilities. At the same time, higher percentages of students than in 2024 reported that their teachers asked them to do more sophisticated tasks, such as identifying evidence in a piece of persuasive writing, and fewer students reported a low interest in reading.
