Study examined the test-retest reliability, intra-test reliability, internal consistency, and construct validity of Compass software for computer access assessment. The software measures user performance in skills needed for computer interaction, such as keyboard and mouse use, navigating through menus, and scanning. The current version of Compass includes 8 skills tests in 3 input device domains. Reports summarize results for each test and provide trial-by-trial detail. Fifteen experienced computer users with physical impairments participated in the Compass evaluation. Overall, the results confirm that the Compass skill tests have an appropriate level of reliability and that they actually do measure the computer skills that they are intended to measure. This paper was presented at the 2007 Annual Conference of the Rehabilitation Engineering & Assistive Technology Society of North America.
