Michael Kohlhaas, a super investigator of public records in California, discovered that 22 charter schools in Los Angeles were rated “low performing” this year. If they get the same rating for a second year in a row, they must close, under the terms of the recently passed charter accountability law, AB 1505.
Among the low-performing schools are a couple of KIPPS, some Ref Rodriguez charters, and other highly touted but low performing schools.
Thomas Sowell at the Stanford’s Hoover Institution pointed to NYC’s high-scoring, high-attrition Success Avademy as his evidence for the miracle of charter schools. Los Angeles is not far from Palo Alto. Why didn’t he look there?

Beautiful! Finally, a little bit of regulation.
The closing of a California charter is a superficial way to give the appearance of some semblance of accountability, but it is mostly a publicity seeking gesture. When public schools are low performing, they come after them with an ax, not a pair of scissors. My question is how many of the big chains like Kipp get closed, or do they select a small, independent school that is not politically connected to be the sacrificial lamb each year?
GREAT metaphor: when public schools are low performing they come after them with an ax, not a pair of scissors
except Sewell ignore the attrition rate at Success Academies, which makes the results on which he brags effectively meaningless
