Yesterday I happened to come across a tweet bemoaning the state of reading among fourth graders. Pretty standard stuff. But as things so often do, it got me curious. Here are reading proficiency scores for fourth graders over the past 50 years:
I'm showing this for white kids so it isn't affected by demographic changes over the years. The main problem is that to go back so far I had to look at the NAEP's long-term test, and the LTT doesn't use normal language like proficient or advanced to describe reading ability. It shows only bands of scores, and then describes those scores using incomprehensible gobbledegook. It's truly weird. I did my best to convert this into words that seemed like reasonable translations.
In any case, the thing to notice is that there's been hardly any change—and what there is suggests a slight improvement. Whether it's phonics or whole language; books or iPads; and through all the change from TV to texting to social media—nothing changed. On average, the kids turned out the same no matter what.
And maybe that makes sense. About 25% of kids have an IQ above 110. They're probably all pretty proficient readers. Likewise, about 25% of kids have an IQ below 90. They're probably all either very weak readers or just flatly illiterate. And then you have the 50% in between who end up at various levels of "OK."
And maybe that's that. Maybe the fads and the trends and the quality of teaching only matter at the margins. About a quarter of the population is always going to be barely functionally literate.
The results for Black kids are a little different. Black students score significantly lower than white kids overall, but their proficiency levels have improved somewhat over time. Not a lot, but enough to suggest that changes in teaching have some effect.
With that in mind I began to wonder which states do the best job of teaching Black children to read. Looking at raw scores isn't very helpful since states differ widely on poverty levels and we know that poverty affects school outcomes. But we can control a bit for that by looking at how close Black scores are to white scores in each state:
There's a huge range. Vermont's Black kids are only 9 points behind, which isn't too bad. In Washington DC they're an astonishing 54 points behind.
Even if you remove those two outliers the range is 24 points. That's a helluva lot, roughly equivalent to 2½ grade levels.
Nor does it shake out the way you might think. Plenty of Southern states do fairly well: Texas, Florida, Kentucky, and North Carolina. And plenty of northern states do poorly: Rhode Island, Connecticut, New Jersey, Minnesota, and Wisconsin. It's not clear what the differences are, but it's not much related to ancient patterns of slavery and racism.
