Computerized Adaptive Testing (CAT) is 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. CAT is efficient and quickly identifies gaps in student learning.
Even better is the fact that ATI automates the construction of computerized adaptive tests. Tests are generated by ATI from an Assessment Planner that defines the item pool to be used in selecting items for the adaptive assessment. Automated construction provides ATI the capability to generate customized computerized adaptive tests to meet unique district needs.
The Galileo Computerized Adaptive Testing Pilot is an integral part of ATI’s next generation comprehensive assessment system and is completely integrated into ATI’s Galileo K-12 Online Instructional Improvement System. Adaptive assessments serve many purposes including guiding instruction, monitoring progress, screening, and assisting in placement decisions.
Integration within Galileo ensures that teaching staff and administrators 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 continuous innovation 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 discussed in greater depth in Composition of a Comprehensive Assessment System.
