The Illinois House has approved a bill that would protect students and their schools from being "negatively impacted" if they choose not to take state assessment tests.
Lawmakers approved the measure by a 64-47 vote Tuesday. It would allow students to opt out of a test if they have a request in writing from a parent or guardian.
Chicago Public Schools initially refused to implement new standardized tests in schools this year. The Illinois State Board of Education threatened to withhold funding, and CPS ultimately administered the tests. The exams are based on Common Core standards that are under a national debate about their benefit.
Gov. Bruce Rauner's education secretary warns the legislation could cost Illinois $1 billion a year in federal aid.
