With more than two decades of on-the-ground experience impacting 300,000 educators and 3 million students, NIET's success is grounded in research. The success of NIET's work is evident in the positive findings from evaluations of impact. In NIET's 2022-23 Research Summary, we summarize findings from five new studies and highlight selected findings from studies of NIET partnerships conducted over the past decade. The five new spotlights include: (1) Building Educator Capacity in Rural School Districts in Arkansas and Tennessee; (2) Supporting Principals and School Leaders in South Carolina; (3) Increasing Equitable Access to Effective Educators in Louisiana High-Need Schools; (4) Improving English Language Arts Achievement in Indiana; and (5) Educator Views of Professional Development and Their Intention to Stay in the Profession.
