This paper describes the design, development, and technical adequacy of the Reading Inventory and Student Evaluation (RISE) form of the Study Aid and Reading Assessment (SARA) reading components computer-delivered assessment. The RISE form, designed for middle-school students, began through a joint project between the Strategic Education Research Partnership (SERP), ETS, and a large urban school district, where middle-school literacy had been identified as an area needing improvement. Educators were interested in understanding more about the component skills of their middle-school students, particularly their struggling readers, using an efficient and reliable assessment. To date, results from our piloting of the RISE form with middle-school students have established its technical adequacy. In the future, we plan to expand the RISE to create parallel forms for 6th-to-8th graders as well as to explore development of new test forms at other points in the grade continuum.
