Pre-Kindergarten Education Might Cause Long-Term Disadvantages!

Many educators (and even more politicians) think that getting children into school early produces great educational benefits. However, the data suggest otherwise. Perhaps the most famous results come from the Head Start study by Puma and others. It found that while the Head Start preschool program produced some short-term benefits, those benefits disappeared for most of the students by third grade. Overall, then, the Head Start program had no lasting effect for most students.

To me, this makes perfect sense. After all, if you give a student some education before most of his or her peers, the student will be “ahead” when he or she starts kindergarten. However, since all the students are following the same curriculum, this “head start” doesn’t do much good, because in the end, the students with the advantage are held back. Rather than using the advantage to push them to learn even more, they are taught the same things that are being taught to the other children. As a result, the only real advantage is that the learning is easier at first. Also, since they have already been “socialized” into the group-learning mode used by schools, they don’t have to adjust to it. Once the others have adjusted, however, that benefit also goes away.

My publisher recently made me aware of another study that comes to an even less-promising conclusion. This study comes from the Tennessee Voluntary Pre-K program, a state-run pre-kindergarten (pre-K) program that focuses on children at risk. The authors followed a total of 2,990 students from kindergarten through 3rd grade, and the results weren’t in line with the expectations of the educators and politicians that promote pre-K education.

The students in the study were all applicants to the pre-K program. However, there were only 1,852 spots available. Those spots were randomly assigned to the applicants, resulting in 1,138 who applied but could not get into the program. Those students were the control group, and their educational outcomes (based on state records) were compared to those of the 1,852 students who could get in. Not surprisingly, when kindergarten started, the students who had been in the pre-K program were ahead of those who had not been in the pre-K program. However, those benefits were fairly short-lived.

By the third grade, the control children actually outperformed the children who had been in the pre-K program. While the amount was small, it was statistically significant for both math and science. In other words, from a long-term perspective, enrollment in pre-K programs produced a slight disadvantage, at least in science and math. Please note that the authors also got permission from the parents to evaluate 1,076 of the students in a more detailed fashion than just looking at their school records. They saw nothing in this more detailed analysis that was different from the analysis using just school records.

The authors sum up the situation well in their conclusion:

We are mindful of the limitations of any one study, no matter how well done, and the need for a robust body of research before firm conclusions are drawn. Nonetheless, the inauspicious findings of the current study offer a cautionary tale about expecting too much from state pre-k programs. The fact that the Head Start Impact study – the only other randomized study of a contemporary publicly funded pre-k program – also found few positive effects after the pre-k year adds further cautions (Puma et al., 2012). State-funded pre-k is a popular idea, but for the sake of the children and the promise of pre-k, credible evidence that a rather typical state pre-k program is not accomplishing its goals should provoke some reassessment. (emphasis mine)

I have a suggestion about how to make the gains in pre-K education last longer: Allow students with a pre-K education to learn at their own pace, regardless of what the other students are learning. That way, they can make the most of what they have already learned. The problem, of course, is that individualized learning is very hard to implement in a school, with the possible exception of a Montessori-type school. However, if you are homeschooling, it comes naturally. This is one of the many reasons why homeschooled students excel compared to their publicly- and privately-schooled counterparts. Generally, their parents start their education early, and because they are allowed to learn at their own pace, those early gains continue to pay off in the later years.

    This was an issue with my son, who we had in preschool and pre-k program run by the city parks and recreation. When he got to kindergarten in the K-12 public school system, most of it was basically a repeat. A few of the kids had never been in a classroom. It got better in 1st and 2nd, as his teacher took some interest in him. He’s going into 3rd grade. My son is also ASD1 (what they used to call Asperger’s, and he loves his facts!), so that is another challenge. He’s a grade ahead in math, at least, and is over two grades ahead in Language Arts (English-Reading). What bugged me is that when he went to the library, they seemed to limit his book choices to no more than 2 grades ahead. I told him that while it’s good to respect his teachers, that I disagreed and that he should read whatever he feels he can read. This is a kid who reads the KJV Bible in church when he gets bored with the sermon.

    I’m resisting the temptation to push him more since I fear that he might be bored, but I did give him the Chronicles of Narnia to read over the summer. He’s on the 3rd book and says he likes it.

    His sister, going into 1st, is only a little ahead, but is doing ok. We had her in the same preschool and pre-K program more days per week and it didn’t help her leap frog her brother in any way.

  2. This post reminds me of this one:

    “I don’t know why preschool seems such a stressful time for homeschoolers, but I see this question often: “What curriculum do you use for preschool?” I always just want to reach through the computer screen and give y’all a big hug and let you know it’s going to be OK. They don’t need curriculum. Save what you think you want to spend for high school biology. Believe me. You will thank me when you get there…”
