Educators are constantly looking for the magic bullet--that intervention which will miraculously result in higher achievement scores for students, as well as happier and more productive teachers. The pressure for improvement has caused education to become a "bandwagon" industry. Therefore, educational leaders adopt the latest fad in hopes that it will bring them to the promised land with little or no budget increase. This has been referred to as the LENT-TYNT-NYNT Syndrome, which translates into- Last Year's New Thing -This Year's New Thing-Next Year's New Thing (Markowitz and Elovitz 2001). All too often these "new things" represent a decision-maker's interest, and bear little if any connection to the programs of previous years or to the educational needs of the school or district. However, with the advent of No Child Left Behind and the publics demand for greater accountability, this is no longer acceptable. Thus, the answer lies in the ability of educational leaders to collect, store, analyze and effectively utilize large amounts of data to inform their decision-making. This is where data warehousing can help. A data warehouse is a repository of information collected from multiple sources, stored under a unified scheme, and which usually resides at a single site. In educational terms, all past information available in electronic format about a school or district such as budget, payroll, student achievement and demographics is stored in one location where it can be accessed using a single set of inquiry tools. This article provides 8 basic steps to establishing a data warehouse, and in depth explanations of each step.
