The Boston Globe has the article Charter schools in Boston score higher on key tests. If you are not a Globe subscriber, the only text you get to see is:
Boston charter schools outperform other public schools on three popular barometers of achievement — the MCAS, the SAT, and the Advanced Placement exams — but tend to have lower four-year graduation rates, according to a study being released Wednesday.
If you read the newspaper or have full access to the site, you will see the following about half way through the article:
In Boston, there are 25 charter schools.
The study examined 3,400 students who sought admission to one of the six charter high schools in Boston between fall 2002 and 2008. (The study excluded two charter high schools that closed during that period because of low performance.)
I commented on the article which reported on a study done at MIT.
If there had been more room, the headline might have said “Charter schools score higher on key tests except for the ones that don’t” It is convenient how two schools that would have lowered the averages for the Charter schools were taken out of the study. Perhaps the people conducting the study and doing the statistical analysis could have excluded a similar proportion of low performing public schools from the study.
With MIT accepting huge amounts of funds to build buildings named after the infamous Koch brothers and then this story, perhaps it is true that MIT is selling its soul to the devil in order to raise funds. Now when MIT calls me for an alumnus donation, I just tell them to put it on the Koch brothers’ tab.
