Author Diane Ravitch, a hero of unionized teachers, is leading a new politically active national organization whose purpose is to “give voice to the millions of parents, educators, and other citizens who are fed up with corporate-style reform.”

The Network for Public Education, announced Thursday, hasn’t decided whether it will contribute to candidates, but it will promote them, in the hope that its endorsements will mobilize educators and parents to defeat candidates backed by big-dollar groups like former Washington, D.C., chancellor Michelle Rhee’s StudentsFirst and wealthy donors like New York City Mayor Michael Bloomberg. Ravitch and her supporters staunchly oppose what those donors generally back – an expanded use of standardized test scores, including using them to evaluate teachers and principals, an expansion of charter schools and closure of poor-performing neighborhood schools ­– and have accused them of  trying “to elect candidates intent on undermining and privatizing our public schools.”
