Schools gather, store and use an increasingly large amount of data. Keeping track of everything from bus routes to building access codes to test scores to sports equipment is done with the help of electronic database programs. Large databases designed for budgeting and student record keeping have long been an integral part of the educational landscape. Student information systems such as NCS/Pearson's SASIxp, Skyward, Power-School and other commercial and home-grown programs are primarily designed to hold data, conduct simple searches and create pre-constructed reports. But a continuing trend toward data-driven decision making and educational accountability requires school leaders not to just store data but use it in increasingly sophisticated ways.
