Jersey Jazzman is not only a music teacher; he has been earning his doctorate in statistics at Rutgers University. In this post, he uses his knowledge of classroom and statistics to try to educate the chief editorial writer for the Star-Ledger, Tom Moran, about the difference between the public schools of Hoboken, New Jersey, and the charter school of Hoboken, New Jersey. As you can see from JJ’s graphs, they enroll different children. Moran effusively praises a dual-language charter (which does not have a single student who is an English language learner, has more white students, and fewer impoverished students).

 

 

Jersey Jazzman patiently walks through the data, and in doing so, provides a valuable lesson in why some charters get better results than public schools. Call it canny, call it gaming the system. It always works.
