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.

| Group | 1998 NAEP | 2024 NAEP | Change |

|---|---:|---:|---:|

| White | *268* | *266* | −2 |

| Black | *242* | *243* | +1 |

| Hispanic | *241* | *245* | +4 |

| Asian/Pacific Islander | *261* | *280* | +19 |

| All public-school students | *261* | *257* | −4 |

| Race/ethnicity | 1999 Grade 8 | 2023 Grade 8 | Change |

|---|---:|---:|---:|

| White | *64.5%* | *44.0%* | −20.5 pp |

| Black | 16.1% | 14.9% | −1.2 pp |

| Hispanic | *14.3%* | *29.4%* | +15.1 pp |

| Asian/Pacific Islander* | 3.9% | 5.9% | +2.0 pp |

| American Indian/Alaska Native | 1.2% | 0.9% | −0.3 pp |

| Two or more races | not separately reported | 4.8% | — |

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.

  • I don't assume that. See the first table, even better in shagie's nicely reformatted version.

    You are the person in this discussion invoking race genetics. Why does your mind go there?

Does this actually track over time or is it coincidence? I'm a bit confused why 1998 was chosen out of all years

  • Coincidence? Of course not.

    1998? I wanted a quarter century of Grade 8 and that gives me 1998 to 2024 with NAEP. 2000 reading assessment was Grade 4 only. You can do it with any pair of years.

    • The article says that scores began drifting down around 2012. Gemini is telling me that NAEP peaked in 2013. Elsewhere in this thread there's a claim of an inflection point around 2018 in PISA, which eyeballing Gemini's numbers lines up with NAEP.

      Does this correlate with the racial proportion data?
