No, it doesn’t. It compares each charter school student to a supposed average of equivalent traditional public school students from the traditional public school the charter school student came from. As a result it is ignoring about a third of all traditional public schools. Because it’s measuring improvement from one year to another, it’s ignoring any child in a charter school that has been there only one year including those kicked out after a year or those that didn’t transfer from a traditional public school. The report acknowledges that the feeder schools its comparing is closer in Demographics to the traditional public school system than the students they’re comparing them to.

It’s a report that uses a convoluted system the stack the deck against traditional public schools and excuses that by arguing it’s comparing how particular students would do in public vs charter schools. And I’m not surprised when they say who funded the study.
