An Average Teacher - Really?

Mark Harrington is a 23 year veteran teacher with Dallas ISD since 1999. He chairs the Social Studies Department, has developed curriculum, has lead the Academic Decathlon Team to three straight championships, coaches the mock trial team and is the UIL Activity Coordinator. According to the Teacher Excellence Initiative, known as TEI, he is an average teacher. Mark has not had a salary increase since TEI was implemented three years ago. He was a member of the TEI development committee. But once he began to speak out about some of its flaws, he was asked to leave the committee. He was featured recently by Bill Zeeble on KERA: http://keranews.org/post/teacher-force-behind-seagoville-high
