Indiana is the first state to walk away from Common Core requirements, with Republican Governor Mike Pence signing a bill Monday that puts the responsibility of developing new standards by July 1 on the State Board of Education.

In a statement, Gov. Pence said that he believed the students in the state were best served through standards developed at a state or local level. So far, Common Core standards have been adopted in 45 states and the District of Columbia but Indiana is the first to withdraw its intentions to continue on the Common Core path.

Common Core was developed by the National Governors Association and Indiana adopted the standards in 2010 under then-governor Tony Bennett, also a Republican.

While conservative groups like the Pioneer Institute support Indiana’s decision, and hope that it inspires other states to take the same action, already a few teachers have come out publicly against the change.

In an interview with the Wall Street Journal, math teacher Joel Gramelspacher called Gov. Pence’s move “slapdash” and said that the quick turnaround for new standards will cause anxiety in teachers and will not serve students well. Teachers, after all, have spent the past few years redrafting lesson plans and adapting their own mindsets to the new standards. They will now be asked to change course, and quickly.

Did Indiana really give the standards enough time to come to fruition? And what does this change mean for other states with leaders who oppose Common Core?

Indiana has drawn a line in the sand – who will be next?
