The Intensive Partnerships for Effective Teaching initiative, which was funded by the Bill & Melinda Gates Foundation, was a multiyear effort to improve student outcomes--particularly high school graduation and college attendance among low-income minority students--by increasing student access to effective teaching. The RAND Corporation worked with the foundation to collect and warehouse data from participating sites and to produce annual data dashboards that presented quantitative information about key indicators of the progress of the reforms. During the course of this project, the RAND data team conducted four key activities: (1) defining the metrics that would be used to monitor and assess annual progress and that would appear in the dashboard, (2) collecting the data from the sites to compute the metrics, (3) managing and standardizing the data, and (4) creating the dashboard and reporting the metrics to the sites and the foundation. This report discusses the challenges in defining metrics and collecting data. It also describes how the RAND data team addressed those challenges. Specifically, the authors examine challenges and recommendations in four areas: (1) issues related to defining metrics used to track system performance; (2) issues related to data collection; (3) issues related to managing and standardizing data across sites; and (4) issues related to data confidentiality, data sensitivity, and partnerships. The authors also draw overarching lessons related to the systematic use of education data for periodic program monitoring.
