JEFFERSON CITY, Mo. (AP) -

The Republican-led Missouri Legislature has passed legislation that would task groups of parents and educators with writing new benchmarks for student achievement.

The measure sent to Democratic Gov. Jay Nixon on Thursday could pave the way for Missouri to become the second state to ditch the Common Core Standards, which have been adopted by more than 40 states. Missouri's State Board of Education adopted Common Core in 2010.

Under the bill, state officials would pick teams to develop new school standards for English, math, science and history to be implemented during the 2016 academic year.

Until then, Missouri schools could continue using Common Core in the classroom and for tests that are scheduled to be taken this fall. The Common Core measure is HB1490.
