The document summarizes a study exploring the experiences of principals in South Central Texas whose schools have student populations that are at least 90% minority, at least 90% on free or reduced lunch, and achieve passing rates of 90% or higher on standardized tests. The study found that these "90/90/90" principals provide stable leadership over time by increasing support structures, enhancing trust, and emphasizing relationships while reducing threats to school success. Key themes that emerged included the importance of principal longevity, building trust and relationships, and addressing the needs of the whole child and community.
