Peninsula School District and its schools are using the school improvement process to increase student achievement. Each school has a leadership team to facilitate their staff through data analysis, goal setting, research, and the implementation of a 3-5 year Action Plan that reflects the needs of their students. The school improvement process is a critical part of each school's work to establish a Professional Learning Community within their school as the foundation for the change process. This is a highly collaborative process requiring a shared commitment to increasing student learning over time.
