US charter schools aren’t stuck with the tenure rules that make firing teachers difficult:
“Known as the CREDOstudy, it evaluated student progress on math tests in half the nation’s five thousand charter schools and concluded that 17 percent were superior to a matched traditional public school; 37 percent were worse than the public school; and the remaining 46 percent had academic gains no different from that of a similar public school. The proportion of charters that get amazing results is far smaller than 17 percent.”
Classic Miranda, 2010: “The most valuable information standardised testing can provide is the difference good teaching makes, allowing the lucky child with a good teacher to improve at a greater rate than her contemporaries stuck with duds or mediocrities. This kind of information is, of course, anathema to a union culture hell-bent on preserving a false “see-no-evil” egalitarianism among its membership, where longevity of service is rewarded over excellence, ingenuity is crushed, and children, especially those without involved, competent parents, suffer.
Classic Miranda, 2010: “But the militant ideologues of the Australian Education Union and the NSW Teachers Federation are determined to boycott the tests, ostensibly because they object to the possibility they might be used to rank schools in ”league tables”. The only logical explanation for this madness is the unions are frightened of information. They don’t want Macquarie Fields to be hailed a success or become a model for other schools in impoverished areas. They want to hide failures and condemn another generation of young Australians to illiteracy.
