Screening to Assign Accommodations Tool (SAAT) Project
To develop and validate a measure that provides information on accommodation assignment for students with learning disabilities.
The purpose of this project was to develop a measure which identifies students for whom construct irrelevant variance (CIV) might obscure measurement of their knowledge, skills, and abilities in mathematics. This project is a culmination of more than a decade of research. This research has led us to understand that once students are identified as having risk factors that might interfere with accurate measurement of the tested construct, additional information can be collected to determine the most appropriate accommodations that will reduce the impact of construct irrelevant variance on their observed academic performance. Future research will consist of validating the measure through the use of focus groups.

Research in Mathematics Education (RME)
(RME) is located within the Annette Caldwell Simmons School of Education and Human Development on the Southern Methodist University (SMU) campus. RME conducts and disseminates high-quality, evidence-based research to improve students’ mathematics performance in Texas. Currently, RME is under the direction of Dr. Leanne Ketterlin Geller and is focused on developing instructional systems for teachers. These systems include instructional practices and assessments that lead to sound decision-making by teachers as well as administrative leadership at the district, campus and state levels.
