Interesting chart included on the drop in math scores. In 1973 it was 266 and it peaked in 2012 at 285. IMO the pushback by teacher's unions under the Obama administration undermined NCLB and it dropped to 280 by 2020. But it has collapsed to 271 since the pandemic.

“"...It's alarming to us that the academic growth in 2022-23 was actually more sluggish than the previous year,” said Lewis, co-author of the study. “The students are missing those building blocks in their skills that allow them to understand grade level content.”

The consequences for students with learning loss could be serious, affecting everything from lifetime earnings to incarceration rates. In a paper co-authored by Harvard’s Thomas Kane, researchers estimate that K-12 students on average face a drop in lifetime earnings of almost 2 percent, totaling $900 billion.

As learning declined, so did academic standards. More than 40 states eased requirements beginning with the class of 2020, according to a report in Education Week. Graduation tests and required courses were eliminated, and the number of credits needed to graduate was reduced. Schools also backed off on standard grading with credit-no credit scores, limits on low grades and more...."
