Early murmurs concerning teacher attrition in the United States have risen to an alarming level since the 1990s. Given that half of the 1990s teaching force were/are expected to retire between 2000 and 2010, the cry has been heard loud and clearly throughout the nation. Furthermore, today's fledgling teachers are fleeing at astronomical rates, particularly in economically challenged urban areas. Alternative route certification programmes are one example of states' and cities' attempts to fill urban classrooms with highly qualified teachers. This paper addresses the potential for retaining urban alternative route teachers. What is revealed is that teacher retention, though multi-layered, implicates principals' moral leadership. As such, traditional leadership methods, roles and responsibilities are called into question. The paper addresses the relationships between alternative route urban teacher retention and educational leadership and proposes a discourse in support of moral leadership. Findings suggest that the moral leadership of school building-level principals may favourably impact the potential for retaining alternative route teachers. (Contains 3 notes and 2 tables.)
