Why have student test scores been declining for a decade in America?
It鈥檚 hardly breaking news that American students are behind academically from where they used to be.
But the specifics can get lost in a haze of headlines and data points. reviewed multiple pieces of testing data to find out where U.S. students stand on learning loss and recovery.
In sum: Test scores have been for over a decade. There are some signs of recovery in math, but not many in reading. Learning declines are not a distinctly U.S. phenomenon and are not even limited to schoolchildren. Researchers are only just beginning to wrap their heads around the causes of this.
Confident claims about what鈥檚 going on here are , though policymakers can鈥檛 wait for perfect evidence to act.
鈥淲e should resist the notion of trying to put our finger on the one thing we can change that will solve this problem,鈥 says University of Virginia researcher James Wyckoff, who recently a paper on declining achievement. 鈥淚 think it really results from many things in and out of school.鈥
Here are some key takeaways from the review of the data.
Learning declines have been substantial and pervasive.
Consider one example from the National Assessment of Educational Progress, or NAEP: In 2013, 74% of American eighth graders scored at the basic or above level in math, the highest figure since the test started in 1990. In the most recent round that number fell to 61%, hitting levels last seen in 1996. Scores have fallen in other and , too.
Despite a small handful of , these declines have been remarkably widespread. Eighth grade math scores fell in almost every single state during this period; no states saw increases. Although schools that were closed longer during the pandemic tended to bigger declines, even those that quickly reopened have been by learning loss.
This trend started before the pandemic.
Test scores, particularly in math, had generally been for a few decades until about 2013. Then a and hit. The aftershocks of the Great Recession on families and school budgets an initial cause. Yet even by 2019 there was still no sign of recovery. Then the bottom fell out further after the pandemic.
Two groups have been hit hardest: low performers and girls.
On a wide variety of tests, starting the pandemic, the gap between the lowest- and highest-performing students . That鈥檚 not because high performers have surged ahead but because low performers have fallen further behind.
More recently, since the pandemic, girls鈥 scores have more sharply than boys鈥.
Some good news: Math scores are starting to trend up again.
Every state with consistent testing data that more students are reaching proficiency in math now compared to 2021. Math results have also on the NWEA exam and on the fourth grade (but not eighth grade) NAEP. Still, most data indicates that these scores have not bounced back to pre-pandemic levels.
There鈥檚 been inconsistent recovery at best in reading.
Reading and math results have followed curiously different trajectories. On the most recent NAEP, reading scores actually fell even further. On state exams, reading achievement has been all over the map. Pennsylvania, for instance, has had solid recovery in math, but reading scores have downward.
The U.S. is hardly alone in its achievement woes.
Many other countries are grappling with falling test scores, too. This has shown up on an exam of 15-year-olds known as the , as well as on the , a math and science test of fourth and eighth graders. Relative to the rest of the world, the U.S. trends look a bit worse on TIMSS, but a bit better on PISA.
The U.S. is in its sharply growing gap between the highest- and lowest-performing students.
Also, test scores may be lower among adults and very young children.
Some data that children who are just entering school are doing so with lower levels of readiness in reading and math. Another of adult skills showed drops across the age distribution between 2017 and 2023 in literacy and numeracy.
This adds a new wrinkle. 鈥淔actors outside of school might play a considerable role鈥 in learning declines, writes Nat Malkus of the American Enterprise Institute in a from last year.
How concerned should we be? Pretty concerned!
When children know more, as measured on tests, they lead more productive lives. Countries with higher test scores tend to see stronger economic growth. These scores are of students鈥 skills, but they do matter.
Test scores are not in entirely uncharted territory, though. A long-running test of 13-year-olds that math scores in 2023 were at the lowest point in recent decades but remain comparable to scores from the 鈥80s and early 鈥90s and higher than those in the 鈥70s. Reading scores have dipped to levels last seen in the early 2000s.
So what explains all this? Researchers aren鈥檛 quite sure.
Two detailed analyses, by and , have tried to parse what is driving these trends. Neither concluded with definitive answers. 鈥淭here is remarkably little understanding of the nature of either the sustained achievement gains prior to 2013 or the subsequent losses thereafter,鈥 writes Wyckoff in his paper, titled 鈥淧uzzling Over Declining Academic Achievement.鈥
That said, it鈥檚 very likely that the pandemic and its associated to life in and out of school played a significant role. Another theory is that easing off school accountability pressure 鈥 which drove learning gains in the early 2000s 鈥 has contributed to recent score declines.
Perhaps the leading hypothesis is the proliferation of phones and screens, although Wyckoff notes that 鈥渄irect causal evidence鈥 on this question 鈥渋s limited.鈥 That鈥檚 beginning to change.
One linked school phone restrictions to better test scores.
These learning challenges are not particular to American schools and may not even be largely caused by changes within schools. Yet they remain a challenge that schools and educators must confront.
