President Obama signed into law the Every Student Succeeds Act, the reauthorization of the Elementary and Secondary Education Act, on December 10, 2015. "Learning Forward's focus in this new law is its improved definition of professional learning," said Stephanie Hirsh, executive director of Learning Forward.

We concentrated our advocacy energy on this element of the legislation because that definition applies to the references to professional development that appear throughout the law."
