Persistence of reading problems: Research-based fact or urban myth?

Last week, I heard from the Education Writers Association requesting information about what happens to children who don’t learn to read well by third grade… Do they drop out of high school? End up in jail? Become wards of the state? Go into politics? (Okay, they didn’t really ask that last one, I was just checking to see if you were paying attention.) The Writers had checked NAEP reports and the Department of Education, but found no help there. So what really happen to kids who don’t read well early?

Longitudinal studies show that early learning problems tend to be persistent. There are strong correlations between early reading skills and later academic attainment. That means that the kids who are learning well in grades 1 and 2, tend to continue to well right into high school. The studies have been done over various time points, but generally they find a very strong consistency from grade 1 through about grade 11 (see citations below for the evidence).

It shouldn’t be surprising that the past is prologue. Scientists who study children’s learning tend to be naturists or nurturists, but either way the story comes out the same. The naturists claim that learning is governed mainly by genetically-inherited brain functioning (IQ, intelligence, ability, etc.). They would conclude that children who have strong ability to learn early on will continue to exhibit such ability as they get older as long as nothing physiologically goes wrong the brain will keep learning well.

The nurturists tell a very similar story. Some children live in supportive environments with parents who talk with them, read to them, send them to good schools with other nurturing adults, etc. Of course, if kids are in stimulating and supportive environments early on they tend to stay there (the rich kid thrown into poverty without benefit of parents is a staple of Dickensian fiction, but a rather rare event in real life in 21st century America). Kids who start out in lousy schools, tend to stay in lousy schools.

The things that make learning work early on are the same things that make learning work later and so kids who do well early on tend to continue to learn (and, of course, this means that the kids who start out having a hard time continue to have difficulty). With reading, the successful kids get the added benefit of being able to read well, which has a functional benefit later on (so even if they have a bad high school teacher, these students can sometimes even read around this temporary impediment).

However, though early reading success or failure translates into later school success or failure is the pattern more than 80% of the time, there are always a few outliers who manage to overcome their initial limitations (again, because they are really smart or live in really smart environments that are arrayed to address the problem). This last point is really important, because it says that redemption is possible. Just because your child is having trouble with reading does not mean this problem has to persist. Good teaching (in big doses) can solve this problem for most kids. Redemption is possible.

So, what of the more dramatic claims? High school dropouts do tend to have somewhat lower reading scores than other kids, but the correlation between dropping out and reading level is pretty limited. That means, for the most parts, kids leave high school for lots of reasons, low reading scores being only one of the explanations (good readers drop out too—I did, for instance—and poor readers often stick around and graduate—just because they can’t read well doesn’t mean they’re stupid). I’m aware of no studies that look at high school graduation longitudinally so can’t say directly whether early low readers are more likely to drop out (they probably are, but how much the chance of this is increased is unknown—I suspect the increase would be rather small given the low relationship between reading and graduation).

The idea that early reading problems translate into prison terms is urban myth. No such studies exist. Data do show that incarcerated youth suffer startlingly high rates of reading disability (something like 5 times the normal incidence)… but most kids with reading problems DO NOT end up in jail, so a strong relationship between early reading difficulty and later criminal activity is not likely (and people like Bernie Madoff can read very well). Despite the claims that school achievement levels are taken into account by those who plan the building of prisons (they do not), the relationship between prison time and literacy is rather murky.
