I would love to see the data from the original study, because I think I have an easy explanation for the phenomenon they observed. It is related to, but not quite like "teaching the test".
Public schools teach a core curriculum focused on academics related to those found on standardized tests. Although there are "minor subjects" like music, art, etc. taught in the public schools, most of a public school kid's day consists of math, reading, and when older social studies and science.
A private school might be a fine arts academy or it might be a religious school. I was thinking about a school in Michigan, the Interlochen music school. It's quite famous, and very expensive. They study music. I'm guessing that their average student is quite bright, so they probably have above average math scores. However, they spend a lot of time studying music, and I'm guessing that means they cut back on the math studies. They would be a very high socio-economic class school, and their test scores would be above average, but not as high as the rich suburban public school.
Likewise, a Jewish school that spends an hour a day on Hebrew has to leave an hour a day out of some other subject. Learning a foreign language, even Hebrew, can be quite useful, but it won't show up on a standardized test.
The result is that a "rich" private school might not do as well as a "rich" public school because it might be a specialized school whose subjects aren't tested.
But when considering the implications of the study on schools of choice programs, what has to leap out is that the socio-economic class of the student body is a major contributor to academic success. Moral of the story: If you want your kid in a school with some high-achieving classmates, and you can't afford private school, move out of your lower class neighborhood.
