The purpose of this èßäÊÓƵapp funded research project is to examine the appropriateness of innovative item designs for accurately measuring student knowledge and skills in algebra. Items are designed using the principles of universal design for assessment as well as emerging theories about accommodations to support students with disabilities.

The purpose of this project is to design, develop, and implement a prototype of a maximally accessible assessment system in mathematics. We embed principles of universal design in the development of a middle-school math test targeting algebra skills. We pilot test the items to evaluate item functioning and conduct an experimental study to investigate the comparability of scores under standard and universally designed formats for students with and without disabilities.
