This dissertation explores factors that influence high achievement in economically challenged minority schools. The purpose is to identify distinguishing characteristics of high performing schools compared to acceptable performing schools with similar demographics in Texas. Interviews and documents from principals, teachers, and staff from 12 case study schools will be analyzed using Collins' "Good to Great" framework to code for disciplines of leadership, thinking, and action. The results aim to accelerate improvement in accessibility and quality of education for underserved students.
