About Us

Our team is passionate about supporting states in building a diverse, talented educator workforce for every student. 

Student-Demographic-Data

From 2012-2019, the Center on Great Teachers and Leaders was a national content center under the federally funded Comprehensive Center Network. Following the grant's conclusion, AIR continues to operate the GTL Center and offer services across a range of core evidence-based talent management strategies.

Passionate, Practitioner-Focused Researchers and Consultants

The GTL Center team has a deep bench of national experts ready to deliver a comprehensive set of services to meet your unique needs. Our team includes former teachers, principals, and teacher leaders, including National Board Certified Teachers. As former practitioners who have worked in classrooms, schools, districts, and state agencies, we know first-hand what it looks like when a school system works, and when it does not. We're passionate about using effective strategies to help states and their districts build diverse, talented teams of educators as the foundation for student success.
