Abstract
While the demands of teaching continue to escalate, teacher development has changed relatively little over time, leaving many of today's teachers feeling underprepared, overwhelmed, or demoralized with few opportunities to make real change. Teacher leadership holds promise for both addressing challenges within schools and empowering teachers. Wesley L.C. Henry, Bryan A. VanGronigen, Meredith L. Wronowski, and James L. Olive highlight how a large urban school district in the United States created, resourced, and implemented a program to develop a corps of teacher leaders who used what they were learning to analyze and critique local school improvement plans. They then presented their ideas to administrators and collaborated with their colleagues to implement more responsive improvement efforts.
