If you take the 1998 NAEP 8th grade reading scores by race, re-weight them by the new 2024 demographic makeup of American 8th graders, you will find a predicted point decline of 4.6, rather close to the actual 4 point fall over the period.
Over the same period, reading scores actually improved somewhat for each of the 1998 poorly scoring groups (and quite a bit for Asians), but the poorly scoring groups simply make up so much more of the population now that it drags everything else down.
The challenge here is that you're assuming performance by race should be constant over time. Maybe that's true, maybe it's not, I think a richer analysis with wealth, parental education, english as a first language cofounders might be helpful.
Also if you want to entertain the theory that it is racial/genetic, it'd be important to do that analysis on a continuum since a lot of people who are "minority X" may be more than 50% white or there may be trends in that over time.
