Championed by California-based Parent Revolution, and adopted first by California in early 2010, more than a half-dozen states now have parent trigger laws. The parent trigger, which allows a majority of parents at a low-performing school to vote to seize control from the local district, has been wielded at four California schools. Is the parent trigger a good idea? Can empowered families transform the system one school at a time? Making the case for the parent trigger is Ben Austin, executive director of Parent Revolution and former deputy mayor of Los Angeles, in his contribution "Empowered Families Can Transform the System." Questioning the merits of the trigger is Michael Petrilli, vice president for policy at the Thomas B. Fordham Foundation and an executive editor of "Education Next," in his contribution "There's a Better Way to Unlock Parent Power."
