Over the past five years, the No Child Left Behind Act, with its mandates for collecting and documenting student achievement statistics, has fueled a surge in the volume of data collected by schools, districts, and state education departments. This information explosion has gone hand in hand with technology's growing affordability and availability, and the realization by school officials that they can put data to work to improve both administrative and instructional processes. Yet as the collection and use of data has grown, a subsequent problem has emerged--where to store it all, while ensuring it remains protected yet accessible, usable, and meaningful. This article discusses data warehouse solution and the significant challenges of implementing it. A data warehouse solution allows school officials to not merely store data in one place, but to analyze the data they collect, examine trends and statistics, and put data into the hands of teachers in near real-time. Empowered by that data, teachers and administrators can then identify individual student weaknesses and make the necessary adjustments to address them before it is too late.
