The peak was in 2012

           2012  2020  2023
  Reading   263   260   256
  Math      285   280   271
So people are looking at Covid and that's probably not enough. The scores are closer to those of the 80's than those in the 90's and 00's

My non-controversial theory: It's all the attention-span-shortening stuff.

- tech apps starting with infinite scroll (facebook, 9gag, Instagram, etc.)

- media/tech shortened content: shorter tv shows, short video content, etc.

(Tiktok is the "state of the art" of those 2 trends pushed to the max)

Specifically, we're getting more & more addicted to things that increase the dopamine spikes frequency, making it increasingly difficult to go in deep focus work.

We don't have any NAEP long-term test results for years between 2012 and 2020, because they were canceled due to budget cuts[1], so we can't use the linked data to determine whether the decline started before or during COVID.

We do have the NAEP main series test results[2]. At a first glance at the math results[3][4], it appears they peaked in 2013, then fluctuated through 2019, then dropped significantly in 2022 and somewhat rebounded in 2024, which really does suggest COVID.

Demographic change is the obvious explanation.
