Student test scores saw precipitous declines in math and reading over the past two years, according to new data from the National Assessment of Educational Progress, commonly known as the nation’s report card.

The 2022 scores, which measure student proficiency in reading and math, are the first edition of the nation’s report to be released since COVID-19 pandemic policies forced schools nationwide to close their doors, in some cases up to a full year.

The biggest score declines were in math, which the National Center for Education Statistics said in a press release was the biggest decline ever recorded. For fourth graders, math scores declined by 5 points to 236 from their 2019 number of 241, while eighth grade scores plummeted 8 points from 282 to 274.

In reading, both fourth and eighth graders saw 3-point declines from 2019. Fourth grade scores fell from 220 to 217 and eighth grade scores from 263 to 260.
