Common Education Data Analysis and Reporting System (CEDARS) What is CEDARS? The Common Education Data Analysis and Reporting System, known as CEDARS, is North Carolina's PreK-13 State Longitudinal Data System. The system is composed of various DPI source data collection systems, a student and staff identification system, a centralized data repository, and associated reporting and analysis (or "business intelligence") tools. Why is CEDARS important for NC? CEDARS supports NC's efforts to use high-quality data about students, staff, programs, and finances to make policy and service decisions that will improve student outcomes. Specifically, CEDARS will enable state, local, and federal policymakers and service providers to analyze trends and relationships between various educational factors and student performance over time. Establishing the Unique Identifiers (UID) for student and staff was the first step in the NC Department of Public Instruction's (DPI) multi-stage effort to create CEDARS. These identifiers, over time, will enable matching of student and staff data across DPI data collections. The CEDARS Data Warehouse and Reporting System contains various DPI source data in a centralized data repository. CEDARS will, over time, increase local capacity to track student performance and assist local educational leaders in making data-driven decisions.
