We believe in the possibility of accelerating improvement in education by catalyzing scientific-professional learning communities aimed at solving high leverage educational problems. An essential question follows: What is entailed in developing the technical capacity, social organization, and cultural norms of networked improvement communities so that they function as scientific-professional learning communities? We take up this question by positing a framework for NIC health and development that highlights these dimensions of this organizational form. All of our work is grounded in our Improvement Network Health and Development Framework.
