"a longtime pre-k skeptic"...
Maybe his mind is already made up, and he gets points from his political base for bashing Pre-k...but I'd be curious to ask Mr. Dunn what he thinks about early childhood development and education for his own 5 children.
from the Pre-K report itself: "Arguably, the greatest limitation of this study is that educational records do not indicate whether students participated in any Pre-K program other than Tennessee’s Pre-K"
So what are we really comparing? We don't know if the other kids went to Pre-k or not. TN Pre-k is providing a number of students with early development and literacy that they otherwise wouldn't have. It's clear from Vanderbilt's study that Pre-K is making a difference.
The Strategic Research Group's report found that some of the gains fade out by 3rd grade, again, not against a control group of kids. Is that more a problem of K-3 and the early elementary teachers?
Also, to emphasize -- we're measuring test scores -- not social/emotional indicators -- and long term indications if that student will graduate high school or how many crimes he or she will commit.
Gets me back to point #1 -- if early literacy and cognitive development is important for Mr. Dunn and his children, why not every child in Tennessee, especially those who might not be as privileged to be in the income bracket of Mr. Dunn?
