The Dallas Independent School District (DISD) sits in the heart of a large, diverse and dynamic region with a metropolitan population of 6.5 million people in the 12 counties in North Central Texas. The district is the second-largest public school district in the state, and the 14th-largest district in the nation. In March 2015, the district released theAccelerating Campus Excellence (ACE) initiative to transform campuses that were designated as Improvement Required (IR) by the Texas Education Agency for multiple years. The Accelerating Campus Excellence (ACE) initiative was based on the principle that transforming schools requires strong leadership, effective teachers and an environment of high expectations for students and staff. The ACE program offered competitive stipends to incentivize top teachers and principals to relocate to some of the district’s most challenged schools.
