When the National Assessment of Educational Progress (NAEP) program releases its reports on student achievement in various subjects, the data are added to the NAEP Data Explorer (NDE) website. The NDE has been shown to support reflective educational practices in the social studies. Working with assessment data can stimulate ideas for how teachers can critique and evaluate curriculum making and instructional practices. However, there are no published accounts of geography teachers using the NDE for such purposes. To illustrate how NAEP data can address questions of concern to geography educators, this article reports the results of a study that investigated these questions. A discussion of the NDE analysis and how the results highlight the potential of using NAEP data to support reflective educational practices in geography is also provided.
