The MTA supports the opt-out movement — the right of parents to opt their children out of state standardized tests. Opting out, or refusing the test, is a powerful way to protest the misuse of high-stakes tests in Massachusetts public schools. With each year the opt-out movement is growing. Last year, 640,000 students across the country refused to take state standardized tests. The largest number of students to opt out was in New York. In Seattle, the entire 11th-grade class at the Nathan Hale High School boycotted the state test in reading and math.
