We all have had a teacher who's shaped us, inspired us, even scared us, and whom we can credit with having empowered us to become who we are today. In his third documentary to look at education in America, Davis Guggenheim brings us "TEACH," which asks the question: what does it take to be a teacher? Offering a rare glimpse inside four public school classrooms, Guggenheim invites us to follow the struggles and triumphs of America's education system through the eyes, minds and hearts of its most essential resource: teachers. A two-hour special television event presented by Participant Media, "TEACH" is set to debut on the CBS Television Network on September 6th at 8:00 pm ET/PT, and on Participant's new network, Pivot, on September 18th at 8:00 pm ET/PT.
