Good for them!
Check it out:

Gov. Mary Fallin (R) of Oklahoma has signed a bill that will repeal the Common Core education standards in her state and replace them with standards to be developed by the state of Oklahoma. The new standards must be proven to be sufficiently unlike the Common Core standards.

Fallin signed HB 3399, which passed with overwhelming bipartisan support. The new law repeals the adoption of the Common Core standards and directs the State Board of Education to create new, more rigorous standards by August of 2016.
