The U.S. is stress-testing Herbert Stein's law like never before, but maybe the economist's famous dictum—trends that can't continue won't—is being vindicated in education. Witness the support of America's mayors for "parent trigger," the public school reform that was denounced as radical only a few years ago but now is spreading across the country.
Over the weekend in Orlando, the U.S. Conference of Mayors unanimously approved a resolution endorsing new rules that give parents the running room to turn around rotten schools. At "persistently failing" institutions, a majority of parents can sign a petition that turns out the administrators and teachers in favor of more competent hires, or dissolves the school, or converts it to a charter. Teachers unions loathe this form of local accountability.
The mayors note that this reform is targeted at the 2,000 or so high schools that count as "dropout factories," where more than 40% of the freshman class fails to graduate. Most are in poor or minority zip codes where kids and parents have no other options. These 2,000 schools produce—if that's the word—51% of U.S. dropouts.
The endorsement push was led by Antonio Villaraigosa of Los Angeles—the union bosses are an "unwavering roadblock to reform," he said—as well as Michael Nutter of Philadelphia and Kevin Johnson of Sacramento, liberals all. Most of the mayors are Democrats. Parent trigger was a California inspiration, instituted in 2010 despite opposition from unions, which are suing to stop its implementation in the cities of Compton and Adelanto. It has since spread to Texas and Louisiana and variants are under consideration in 20 states.
