The 2010 manuscript describes an innovative experience-laden curriculum for aspiring school leaders at the University of South Alabama developed between 2005 and 2007. The 2011 manuscript revisits the topic with a completed research study providing data related to responses from mentor principals, cohort members, co-workers, and observers.
