This study examines the impact of a federal Teacher Incentive Fund grant award that expanded a partnership between Cross County School District and the National Institute for Excellence in Teaching (NIET) to create systems that support ongoing, continuous improvement for teachers. Through the implementation of the TAP System for Teacher and Student Advancement, the district is implementing a coherent and integrated set of strategies that are rooted in a common vision for instructional excellence. Results from the first three years of the grant indicate progress towards increasing teacher collegiality, improving teacher effectiveness, increasing teacher retention, and impacting student achievement. During the grant period, teachers reported increased levels of collegiality in their school. Additionally, the percentage of teachers rated as effective has increased and retention of these effective teachers has improved. Finally, student performance on state standardized assessments improved in all subjects in Cross County School District, surpassing that in comparison districts.
