Across the country, educators, parents and students are saying that there is too much testing in our schools and that testing is taking valuable time away from teaching and learning. These concerns are legitimate and merit attention. School district officials have the opportunity to respond to concerns about over-testing by leading a conversation among educators and the broader community that directly addresses the amount of testing -- and points the way toward a more coherent, educationally-sound approach to assessment. This "Student Assessment Inventory for School Districts" is a tool district leaders can use to take stock of their assessments and assessment strategy, and do so from a student perspective. The tool supports a process by which districts evaluate the assessments students are taking, determine the minimum testing necessary to serve essential diagnostic, instructional and accountability purposes, and work to ensure that every district-mandated test is of high quality, is providing the information needed for specific school and district purposes, and is supported by structures and routines so that assessment results are actually used and action steps taken that will help students. We encourage local district leaders who use this inventory to discuss the outcome with parents and the school board. What tests have been eliminated? How will the remaining tests be used, and why are they important?
