From New York Times/Associated Press:

On April 28, Indiana became the first state to adopt and then replace the Common Core standards. Indiana’s State Board of Education voted 10 to 1 to endorse new benchmarks for math and English, which were created by a panel of faculty from Indiana universities and representatives from science and technology industries. Indiana adopted the Common Core in 2010, but various individuals argued that the standards were created without adequate local input. The new standards are a hybrid of the Common Core and prior Indiana academic standards, and analysts have remarked that these new standards are in large part very similar to the Common Core in many areas.
