The aim of this project is to develop the skills of school leaders to establish learning communities where data are used to improve educational outcomes. Specifically, the project will help school leaders develop a vision and strategy for using data to improve educational outcomes; increase the understanding of how to maximize the use of available data among school leaders; build key data, use skills such as assessment literacy, question formulation, data collection, data analysis, action planning, and progress monitoring; and help leaders use data to get informed about decisions regarding the policy, programs, teaching practice, and student placement in schools. The project will provide the framework to establish professional learning communities in each pilot school; document state-of-the-art research on the use of educational data in schools; offer an online school-wide data use survey tool to assess the types and extent the use of educational data in schools; develop online course modules that work in concert to build professional learning communities focused on data use; create data analysis tools, facilitator materials and a course website for administration of the course and dissemination of materials. The project is targeted squarely at educational leaders organized in school-based professional learning communities. Members of the learning community include staff such as student information system managers, guidance/counselling directors, heads of departments, lead teachers, literacy and math coaches, and school administrative leaders (headmasters). In addition to students, other groups that will benefit from the project include educational leadership training institutions/organizations, district/regional administrators and leaders, research institutions (e.g. Universities), and teachers.
