This study examined three high schools in a large urban school district in Texas that achieved an academically acceptable rating after being sanctioned to reconstitute by state agencies. Texas state accountability standards are a result of the No Child Left Behind Act of 2011 (NCLB). Texas state law requires schools to design a reconstitution plan after the second year of receiving an academically unacceptable school rating for failing to meet the required standards on state assessments, dropout rates, and graduation rates. The plan must be implemented by the third year. A mixed methods approach was used to uncover the strategies that were successful during the restructuring initiative. Data was obtained from three sources: interviews, document analysis and surveys. Interviews were conducted with district administrators, campus based administrators and teachers of the three high schools. A sample of core content teachers were surveyed using questions from the MetLife Survey of the American Teacher: Collaborating for Student Success. Results revealed that each school chose to engage in a major form of restructuring that included the formation of a themed based magnet school. A team approach was used to devise, implement, and monitor the reconstitution plan. Common strategies unveiled in the study included the use of common assessments, collaborative planning among core teachers, professional development, continuous monitoring of student absences, extended learning times for students, and a focus on college readiness. Survey data revealed that the majority of teachers believed that collaboration positively impacted student achievement. It is recommended that schools undergoing restructuring choose a reconstitution option that allows for flexibility, use multiple resources to foster school improvement, and develop restructuring plans that serve as living documents. Further research is needed to study the principal's role in achieving an academically acceptable rating. This study could also be expanded to compare restructuring strategies of high schools across the country that has been forced by federal mandates to reconstitute.
