Comprehensive, reliable, and valid assessment is essential for individually tailored, appropriate, and effective intervention planning and implementation. Research, education, and practice using an Ayres Sensory Integration® (ASI) approach have a long history of prioritizing comprehensive assessment. To meet the need for a set of tests that will fully evaluate the constructs of ASI with psychometrically strong, internationally appropriate, and easily accessible measurement tools, the development of the Evaluation in Ayres Sensory Integration® (EASI) has been initiated. This article introduces the EASI, describes the overarching plan for its development, and reports the results of promising preliminary analyses of discriminative validity data.
