OSEP's Results Driven Accountability is designed to assure educators have the supports necessary to address the needs of all children, including children with disabilities. OSEP-funded Centers are encouraged to support state education systems as they take charge in making systemic changes that lead to improved outcomes for students. Data are now available that demonstrate capacity for change can be purposefully developed in complex state education systems by using active implementation science as a change method. The data are based on a standard measure that has been used to systematically assess capacity development within and across states.
