A parent trigger is a legal maneuver through which parents can change the administration of a poorly performing public school—most notably, by transforming it into a charter school. The first parent trigger law was passed by the California legislature in January 2010. Similar laws have been adopted subsequently by Louisiana, Mississippi, Connecticut, Texas, Indiana and Ohio. The law has been invoked by parents in the Compton, Adelanto, Anaheim, and LAUSD school districts of California.
