Ms Varner proudly quotes a study which reports:
"60% of the charter schools performed with similar or better success than the traditional public schools in reading and 53 percnet (sic) of charter schools performed with similar or better success in math compared to traditional schools."Those of us with math skills instantly recognize that this means that 40% of charters had WORSE results than traditional public schools in reading and 47% of them had WORSE results than traditional public schools in math. Rather than using this data to support the creation of charter schools, I would use these results to oppose them.
Note that we don't know what share of the charter schools showed performance that was similar to that of traditional public schools, but, if this study's results were anything like what the CREDO study found, it is likely to be around 50% or so. This leaves a very narrow band of charter schools that actually out-performed public schools. This data is not an endorsement of charters; it is a condemnation.
I'm more than a little troubled that Ms Varner can't see this. She has the loudest voice in the state education issues, and she doesn't appear capable of getting information out of data.
