Increase measurement precision this fall by piloting Computerized Adaptive Testing (CAT) - a form of assessment in which administered items are selected based on the ability levels of the students. Initial item selection is typically based on the assumption that the test taker is of average ability; subsequently selected items are based on ability estimates obtained from preceding responses. This approach optimizes precision by increasing the selection of items that are neither too easy nor too difficult.
The Galileo Computerized Adaptive Testing Pilot is an integral part of ATI’s next generation comprehensive assessment system. Engineered by ATI’s Research and Development and Assessment and Instructional Design teams, Galileo Computerized Adaptive Testing and the entire comprehensive assessment system are completely integrated into ATI’s Galileo K-12 Online Instructional Improvement System.
Integration within Galileo ensures that educators, administrators, and specialists have easy and rapid access to the full range of innovative assessment, reporting, curriculum, and measurement tools provided all within one system. ATI’s comprehensive assessment system is part of our ongoing commitment to “think ahead” so that school districts and charter schools can continuously build their own capacity to lead change in ways that enhance the quality and impact of education on our nation’s children and youth.
ATI's approach to Computerized Adaptive Testing is explored in greater depth in Composition of a Comprehensive Assessment System.
