Arne Duncan, previous U.S. Secretary of Education under President Obama, announced the launch of the Teach to Lead initiative and provides a rationale.
In this speech, Arne Duncan says, "Teacher leadership means having a voice in the policies and decisions that affect your students, your daily work, and the shape of your profession. It means guiding the growth of your colleagues. It means that teaching can't be a one-size-fits-all job—that there must be different paths based on different interests, and you don’t have to end up with the same job description that you started with. It means sharing in decisions that used to be only made by administrators -- and the best administrators know they’ll make better decisions when they listen to teachers."
Duncan also announced the Teach to Lead Initiative, a joint effort of the U.S. Department of Education and the National Board for Professional Teaching Standards.
