US high school students lose ground in math and reading, continuing yearslong decline

A decade-long slide in high schoolers’ reading and math performance persisted during the COVID-19 pandemic, with 12th graders’ scores dropping to their lowest level in more than 20 years, according to results released Tuesday from an exam known as the nation’s report card.

Eighth-grade students also lost significant ground in science skills, according to the results from the National Assessment of Education Progress.
