The North Dakota Department of Public Instruction (NDDPI) and the R11CC have partnered with the Central Regional Education Association (CREA), the North Dakota University System, and more than 20 Targeted Support and Improvement (TSI) schools and districts to support significant, durable, evidence-based changes. Project activities are aimed at testing and refining evidence-based practices to reduce achievement gaps in student subgroup performance. Improvement science is a problem-solving approach centered on continuous inquiry and learning. Changes in practice are tested in rapid cycles, resulting in efficient and practical feedback to inform school and district system improvements. A core principle of improvement science is that a system’s performance is a result of its design and operation, not simply a result of individuals’ efforts within the system. Building from this foundation, the project is focused on helping school and district teams build a shared understanding about how their systems work, where “bright spots” and breakdowns occur, and what actions can be taken to improve overall schoolwide performance. The team is currently working on providing tools for teachers, principals, and district-level leaders to use at each step of the school renewal journey, from clearly defining the root problem to be solved to scaling up bright spots/improvements.
