Columbia, Mo. - Right now, Missouri is one of 44 states using the common core standards to prepare students for college and careers.
The federal government doesn't require the standards, governors and state education leaders pushed their creation.
But in the past few years common core has become controversial across the u.s., just in the last year here in Missouri. Indiana did adopt the standards, but after a push by opposition, lawmakers forced the state to drop them and create its own standards.
Missouri could be the second state to follow. HB 1490 passed both the house and senate Thursday afternoon. Depending on what Governor Nixon decides, Missouri could be back to the drawing board.
ABC 17's Meredith Hoenes talked to both supports and opposition of common core to find out why the controversy.
