This detailed diagnostic data is widely used by districts for universal screening, progress monitoring, and meeting federal requirements for identifying students who need intervention. The accompanying instructional program provides personalized online lessons targeted to each student's diagnostic results.\n\nCurriculum Associates has invested heavily in the research base for i-Ready, publishing studies demonstrating the diagnostic's predictive validity and the learning gains associated with the instructional program. i-Ready competes with Lexia, DreamBox, MAP Growth by NWEA, and STAR assessments by Renaissance Learning in the adaptive assessment and intervention market.
